Description

Technical Field

[0001] The present disclosure relates to surgical devices, and more particularly to a stabilization system for trauma applications.

Background Art

[0002] A trauma plate is an orthopedic device used to stabilize and fix a fracture site in bone. For a fracture site in the foot, a special plate can be used to address fracture sites and bone fragmentation in the foot, ensure proper alignment, and promote healing. The foot and ankle have over 25 bones and 33 joints. The foot can be divided into three main regions: the forefoot, midfoot, and hindfoot. These parts cooperate with the ankle to provide support, balance, and mobility to the body. The forefoot region can include fracture sites in the metatarsal and phalangeal bones. The midfoot region can include fracture sites in the tarsal bones including the navicular, cuboid, and cuneiform bones. The hindfoot region can include fracture sites in the tarsal bones including the talus and calcaneus (heel bone). For complex fracture sites or fracture sites of bones with complex three-dimensional geometries, a repair plate can be used for correction and bone stabilization. Various plates can be used to treat fracture sites and damaged segments in different parts of the body. However, there is still a need for improved plate styles and plating systems that can treat a very large number of fracture patterns and accommodate multiple deformations.

Summary of the Invention

[0003] To meet this need and other needs, and considering its purpose, this application provides devices, systems, and methods for promoting healing and stabilization of fracture sites. Specifically, the plates may include a comprehensive offering of plate forms capable of treating a wide range of fracture patterns. The plates can be used for both final permanent fixation and temporary or supplemental fixation, according to other systems. Specific plate forms can accommodate multiple fracture patterns. The plates can be cut and contoured to accommodate extreme patient anatomical structures. A wide range of screw and plate sizes can accommodate multiple anatomical structures and regions.

[0028] Embodiments of this disclosure generally relate to devices, systems, and methods for fracture healing and stabilization. Plates may include a comprehensive provision of plate forms for stabilizing fractures, dislocations, or repairing deformities. Bone plates may be used to create highly rigid structures with permanent fixation to promote primary healing and stabilization. Alternatively, plates may also be used as temporary or auxiliary fixation.

[0029] A series of trauma and / or repair plates may be used to fix fractures and bone fragments in forefoot, midfoot, and hindfoot applications. Foot fracture plates may be used to address fractures and fragmentation in the foot to ensure proper integration and promote healing. The foot includes three main anatomical regions: the forefoot, midfoot, and hindfoot.

[0030] The forefoot includes the five toes, also known as phalanges, and the long bones or metatarsals that connect them. Several smaller bones together form a phalanx or toe. Four of the five toes have three phalanges, each connected by two joints. The big toe, or hallux, has two phalanges distally and proximally, with a joint called the interphalangeal joint between them. The big toe articulates with the head of the first metatarsal bone at the first metatarsophalangeal (MTP) joint, and there are two tendons on the plantar side of the metatarsal head. The phalanges connect to the metatarsals at the ball of the foot. The forefoot balances the pressure on the ball of the foot and supports a considerable amount of body weight.

[0031] The bones of the midfoot, from medial to lateral, are the first to third cuneiform bones, the cuboid bone, and the crescent-shaped navicular bone posterior to the cuneiforms. The navicular bone articulates with the talus and establishes the foundation for the ankle joint, where the tibia, fibula, and foot converge at the hinge joint. The five tarsal bones of the midfoot work together to form the transverse and longitudinal arches, which help absorb shock.

[0032] The hindfoot, the most posterior part of the foot, includes three joints that connect the midfoot to the ankle: the subtalar joint, the calcaneal cuboid joint, and the talonavicular joint. The calcaneus, also known as the heel bone, is found on the sole of the foot near the ankle, just below the talus, tibia, and fibula of the lower limb. The calcaneus joins the talus at the subtalar joint, which allows the foot to rotate.

[0033] Referring here to Figure 1, a set of plate types 10 configured for the fixation of fractures and bone fragments in the forefoot, midfoot, and hindfoot is shown. 17 different foot plate types may be used in the treatment of various fractures of the foot, including: (a) fifth metatarsal hook plate, (b) fifth metatarsal tab plate, (c) first and second tarsometatarsal plates with joined Lisfrancs, (d) second and third tarsometatarsal plates with joined Lisfrancs, (e) cuboid plate, (f) flower plate, (g) navicular plate, (h) navicular plate with plantar fascicle, (i) utility plate, (j) H plate, (k) tarsal wave plate, (l) tarsal tongue type plate, (m) rafting periplate, (n) talus T plate, (o) talus L plate, (p) talus butterfly plate, and (q) pericalcaneal plate.

[0034] Each bone plate 10 is configured to be positioned, for example, against the outer surface of the bones and / or joints of the foot. The bone plates 10 hold together bone fragments across the fracture site and / or joint, allowing the bone to heal in proper alignment. These plates 10 may be supplied in several variations in surgical trays, including various types, sizes, and configurations. The selection of trays allows the surgeon to select the desired plate during surgery after opening the wound and considering the patient's plating needs. While the set of plates 10 is generally described in relation to stabilizing the foot, it will be understood that the stabilization systems described herein may be used, or adapted for use, for the fixation of other parts or other bones, including the femur, tibia, humerus, clavicle, fibula, ulna, radius, bones of the hand, or other suitable bones or joints. The bone plates 10 may be available in various lengths, widths, and styles based on the patient's anatomical structure and the type of fracture site. The system may be adapted to fix small or large bone fragments, one or more bone fragments, or otherwise to fix one or more fracture sites or joints.

[0035] Referring here to Figure 2, four different screw types 12 are shown that can be used with or without plate 10 in the treatment of various fracture sites, including (a) locking screws, (b) non-locking screws, (c) cancellous screws, and (d) speed screws. Each plate 10 may be configured to receive one or more bone fasteners or screws 12. The screws 12 may be configured to pass through plate 10 and enter the bone, thereby fixing plate 10 to the bone. Although screws are exemplified, fasteners 12 may also include other fasteners or anchors configured to be fixed to or engage with bone, such as nails, spikes, staples, pegs, barbs, and hooks. The fasteners 12 may be cannula-inserted so that they can be guided into position on a guidewire or K-wire.

[0036] Each screw 12 may include a head portion configured to engage with a plate and a threaded shaft portion configured to engage with bone. Screws 12 may have locking and non-locking options. For locking screws of screw type (a), the head portion may include a threaded or textured portion configured to lock the screw 12 to the plate 10. For non-locking screws of screw type (b), the head portion may be substantially rounded and smooth to allow for dynamic compression of the bone. For cancellous screws of screw type (c), screw 12 is a non-locking screw designed to be inserted into cancellous bone. Cancellous screws may have wider threads than cortical screws to allow for better engagement in softer cancellous bone. For speed screws of screw type (d), the screw may have a sharp self-perforating tip with a narrower shaft diameter designed for rapid insertion. Plate 10 may be configured to accept multiple screw sizes representing the outer diameter of the threads of screws offered for each screw type (e.g., 2.0 mm, 2.5 mm, 3.0 mm). In some cases, a screw may be a hybrid screw having one main diameter (e.g., 3.0 mm) on the threads but a head size that matches another diameter (e.g., 2.5 mm). This may provide surgeons with a wider selection of screws to use and may also serve as a bail-out option.

[0037] Referring here to Figure 3, the plate 10 may include one or more openings or hole types 14, 16, 18, 20. The fastening openings 14, 16 may include cylindrical openings, conical openings, elongated openings, threaded openings, textured openings, non-threaded and / or non-textured openings, etc. The openings 14, 16 extending through the plate 10 are configured to accept locking fasteners, non-locking fasteners, or a combination of both locking and non-locking fasteners, which can dynamically compress the bone and / or attach the plate 10 to the bone. For example, a first opening type may include an elongated opening or a dynamic compression slot 14, which allows compression along the bone (between 0.5 and 2 mm, e.g., 1 mm compression) through static insertion of a non-locking screw 12 into the bone and / or eccentric insertion of a non-locking screw 12. A second opening type may include a multi-axis locking hole 16 having a textured portion configured to engage with the head portion of a locking fastener. The locking screw 12 may include a thread or textured portion configured to deform the locking hole 16 and / or engage with the locking hole 16, thereby locking the fastener 12 to the plate 10. A third opening type may include a K-wire hole 18 configured to receive a K-wire guide wire through it. A fourth opening type may include an elongated K-wire slot 20 that allows compression by the guide wire or K-wire. Further details on these and other types of openings are provided in more detail in U.S. Patent No. 11,432,857, which is incorporated herein by reference in whole for all purposes. The plate 10 may have any preferred number of openings 14, 16, 18, 20 in any preferred configuration. These openings allow the surgeon flexibility in positioning fasteners based on preference, anatomical structure, and fracture site. Surgeons may have differing opinions regarding the number, location, and type of fasteners 12. The complexity of the fracture site's location and shape may make it desirable to have as many fastener locations as possible to treat the fracture.

[0038] The bone plate 10 may consist of titanium, stainless steel, cobalt-chromium, carbon composites, plastics or polymers such as polyetheretherketone (PEEK), polyethylene, ultra-high molecular weight polyethylene (UHMWPE), resorbable polylactic acid (PLA), and polyglycolic acid (PGA), combinations or alloys of such materials, or any other suitable material that has sufficient strength to fix to and hold the bone, and is also biocompatible enough to be implanted in the body. Similarly, the fastener 12 may consist of titanium, cobalt-chromium, cobalt-chromium-molybdenum, stainless steel, tungsten carbide, combinations or alloys of such materials, or other suitable biocompatible material. The above list of materials includes many typical materials from which bone plates and bone fasteners are made, but it should be understood that bone plates and fasteners made from any suitable material are intended.

[0039] Referring here to Figures 4A to 4D, a fifth metatarsal hook plate 100 according to one embodiment is shown. Figure 4A depicts the anatomical structure of the foot 4, contoured such that the fifth metatarsal hook plate 100 is positioned on the lateral surface of the base of the fifth metatarsal. The hook plate 100 has a body that extends from a first end or proximal end 102 configured to be positioned on the rough surface of the fifth metatarsal to a second end or distal end 104 configured to be positioned on the body of the fifth metatarsal. The plate 100 includes an upper surface 106 and an opposite bottom surface 108 configured to be in contact with the adjacent bone. The upper surface 106 and the bottom surface 108 are connected by lateral surfaces extending from the first end 102 to the second end 104 of the plate 100. The plate 100 may be separated into three sections: a distal portion 110, a flexed portion 112, and a proximal hook 114. The distal portion 110 may generally have an elongated longitudinal body with a flat outer shape. The curved portion 112 may be angled relative to the distal portion 110, and the proximal hook 114 may extend from the curved portion 112. Although one version of the plate 100 is shown, it is understood that any preferred shape and contour of the plate 100 may be provided depending on the location and type of fracture site to be plated.

[0040] As further highlighted in Figure 4C, the proximal end 102 of plate 100 extends to a prominently curved hook 114 configured to grasp or fix to the rough surface of the fifth metatarsal bone. The proximal hook 114 may define a double hook end terminating as a pair of separate curved projections 116 having sharp or pointed ends 118. The curved projections 116 may be separated from each other by a gap or spacing. The pair of projections 116 may be aligned in parallel or otherwise configured. The curved hook 114 and projections 116 may curve downward in an arc or crescent shape such that the pointed ends 118 curve back toward the distal end 104. The hook 114 may be used to capture an avulsion fracture or Jones fracture at the base of the fifth metatarsal bone.

[0041] The hook plate 100 may be provided with any preferred number and type of openings 14, 16, 18 in any preferred configuration. In the shown embodiment, a number of multiaxial locking holes 16 are positioned along the body of the plate 100. For example, one multiaxial hole 16 may be positioned near the distal end 104, and several multiaxial holes 16 may be positioned toward the proximal end 102. One multiaxial hole 16 may pass through a curved hook 114 and be defined adjacent to a projection 116. The curvature of the hook 114 allows for different orientations of screw insertion. Specifically, the hole axis of the multiaxial hole 16 defined in the hook 114 may be aligned and configured to position the screw 12 intramedullarily through the canal of the fifth metatarsal bone. The remaining multiaxial holes 16 may be used to fix the plate 100 to the bone. Three K-wire holes 18 are provided along the length of the plate 100. The K-wire holes 18 provide additional fixing points for the plate 100. By driving the K-wire through the appropriate holes 18 within the plate 100, the plate 100 can be held on the bone while the adjacent bone screws 12 can be inserted through the multi-axis holes 16.

[0042] As best seen in Figure 4D, the plate 100 may have two dynamic compression slots 14 toward its distal end 104. The dynamic compression slots 14 may be aligned with the central axis of the implant 100 and positioned between opposing K-wire holes 18. The dynamic compression slots 14 of the plate 100 may be useful for compressing an avulsion fracture or Jones fracture of the fifth metatarsal bone. The outer edge of the plate 100 may be scalloped or wavy to follow the hole pattern and minimize potential soft tissue irritation. The fifth metatarsal hook plate 100 may be available in small and large sizes as well as in left and right configurations. Larger plates may feature a slight flexion distally to match the curvature of the fifth metatarsal bone.

[0043] Referring here to Figures 5A to 5C, a fifth metatarsal tab plate 200 according to one embodiment is shown. The tab plate 200 is similar to the hook plate 100 except that a curved tab 214 replaces a curved hook and projection on the proximal end. Figure 5A depicts the anatomical structure of the foot 4 having a fifth metatarsal tab plate 200 having the same contour as the fifth metatarsal hook plate 100 so as to be located on the base of the lateral surface of the fifth metatarsal. The tab plate 200 extends from a proximal end 202 configured to be located on the rough surface of the fifth metatarsal to a distal end 204 configured to be located on the body of the fifth metatarsal. The plate 200 includes an upper surface 206 and a bottom surface 208 having openings 14, 16, and 18 that extend through it. The plate 200 may include a distal portion 210, a curved portion 212, and a proximal tab 214. As further highlighted in Figure 5C, the proximal end 202 of the plate 200 includes a curved tab 214 configured to grip or fix to the rough surface of the fifth metatarsal bone. The curved tab 214 may be curved in an arc or crescent shape. The curved tab 214 may be used to capture an avulsion fracture or Jones fracture at the base of the fifth metatarsal bone. One multiaxial hole 16 may be defined through the curved tab 214. The curvature of the tab 214 allows for different orientations of screw insertion. Specifically, the hole axis of the multiaxial hole 16 defined in the tab 214 may be aligned and configured to position the screw 12 into the medullary cavity through the canal of the fifth metatarsal bone. The tab plate 200 may be available in small and large sizes and in left and right configurations.

[0044] Referring here to Figures 6A to 6E, a combined Lisfranc first and second tarsometatarsal plate 300 according to one embodiment is shown. Figure 6A depicts the anatomical structure of the foot 4 having a combined Lisfranc first and second tarsometatarsal plate 300, contoured to be positioned on the dorsal surfaces of the medial cuneiform, intermediate cuneiform, first metatarsal, and second metatarsal, respectively. The combined plate 300 has a bifurcated body extending from a first end or proximal end 302 configured to be positioned on the medial cuneiform and intermediate cuneiform, to a second end or distal end 304 configured to be positioned on the bodies of the first and second metatarsal bones, respectively. The plate 300 includes an upper surface 306 and an opposite bottom surface 308 configured to be in contact with the adjacent bone. As best seen in Figure 6B, the coupling plate 300 includes first legs 310 and second legs 312 connected by a proximal crossbeam 314. The crossbeam 314 is a transverse beam or connector for the legs 310, 312 at the proximal end 302 of the plate 300. The plate 300 may also include a bridge 316 that connects the two legs 310, 312 of the plate 300 together to increase strength.

[0045] As highlighted in Figure 6C, the proximal end 302 of plate 300 includes a cluster of three multi-axis holes 16 configured to accommodate one or more screws 12 in the intermediate cuneiform bone. The three-hole cluster may be defined at the nearest intersection of the leg portion 312 and the crossbeam 314. The three-hole cluster may be aligned in a symmetrical pattern at the vertices of a triangle, such as an equilateral triangle. The K-wire hole 18 may be positioned at the center between the clusters. As shown in Figure 6D, two additional multi-axis holes 16 may be positioned adjacent to the cluster of multi-axis holes 16, configured to accommodate one or more screws 12 in the medial cuneiform bone. The two additional multi-axis holes 16 may be defined along the intersection of the leg portion 310 and the crossbeam 314. The K-wire hole 18 may be positioned between them. The two additional multi-axis holes 16 may be spaced apart or separated to create space for Lisfranc independent screws that may be located outside plate 300.

[0046] As shown in Figure 6E, the distal end 304 of plate 300 includes the free ends of two legs 310, 312 that provide a series of multiaxial holes 16 for fixing the first and second metatarsals. For example, three multiaxial holes 16 may be provided within each leg 310, 312 in a linear arrangement. The legs 310, 312 may be angled so that the free ends of the legs 310, 312 are furthest apart, mimicking the normal inter-metatarsal (IM) angle between the first and second metatarsals. Each leg 310, 312 may also define a dynamic compression slot 14 to assist in joint compression. The dynamic compression slot 14 may be positioned between the second and third multiaxial holes 16. A K-wire hole 18 may be provided between the first and second multiaxial holes 16. Some portions of the outer edge of plate 300 may be scalloped or wavy, following the perforation pattern, to minimize potential soft tissue irritation.

[0047] The coupling plate 300 may further include a fixture connection interface 318, which allows a separate fixture (not shown) to be connected to the plate 300 for use in arranging Lisfranc independent screws. The fixture connection interface 318 may include a threaded connector having multiple recesses. For example, three circular recesses may be spaced apart around a threaded through-hole. The fixture connection interface 318 may be positioned on the upper surface 306 of a leg 312 adjacent to the bridge 316. The coupling plate 300 may be available in small, medium, and large sizes, as well as in left-hand and right-hand configurations.

[0048] Referring here to Figures 7A to 7D, a jointed Lisfranc second and third tarsometatarsal plate 400 according to one embodiment is shown. The jointed plate 400 is similar to plate 300, having an additional cluster of multiaxial holes 16 at its proximal end 402. As shown in Figure 7A, the jointed Lisfranc second and third tarsometatarsal plates 400 are contoured to be positioned on the dorsal surfaces of the intermediate cuneiform, lateral cuneiform, second metatarsal, and third metatarsal, respectively. Similar to plate 300, the jointed plate 400 has a bifurcated body extending from a first end or proximal end 402 configured to be positioned on the intermediate and lateral cuneiform bones, to a second end or distal end 404 configured to be positioned on the bodies of the second and third metatarsal bones, respectively. Plate 400 includes an upper surface 406 and an opposite bottom surface 408 configured to be in contact with the adjacent bone. As best seen in Figure 7B, the coupling plate 400 includes first legs 410 and second legs 412 connected by a proximal crossbeam 414. The crossbeam 414 may be a horizontal or transverse beam for the legs 410, 412 at the proximal end 402 of the plate 400.

[0049] As best seen in Figure 7C, the proximal end 402 of plate 400 may include two symmetrical clusters of three multiaxial holes 16 designed to accommodate one or more screws 12 in the intermediate and lateral cuneiform bones, respectively. Each hole cluster may be arranged with its hole axes aligned in an equilateral triangle. A bridge 416 may include a thin, curved connector that connects the two legs 410, 412 of plate 400 together to add strength to plate 400. As shown in Figure 7D, the distal end 404 of plate 400 includes the free ends of the two legs 410, 412, which provide multiaxial hole options for fixing the first and second metatarsals, respectively. The holes in a given leg 410, 412 may be aligned with each other in a linear manner. The legs 410, 412 may be substantially parallel to each other and may be narrower than the proximal end 402 of plate 400. Each leg portion 410, 412 may define a dynamic compression slot 14 to assist in compressing the joint and / or K-wire opening 18 for temporary fixation of the plate 400. The outer edges of the distal legs 410, 412 may be scalloped or wavy to follow the hole pattern and minimize potential soft tissue irritation. These plates 400 may be available in small, medium, and large sizes and can be used on either the left or right foot.

[0050] Referring here to Figures 8A and 8B, a cuboid plate 500 according to one embodiment is shown. As shown in Figure 8A, the cuboid plate 500 is contoured to be positioned laterally on the cuboid bone, which is substantially cubic in shape. Depending on its orientation, the plate 500 may extend generally from a first end 502 that is aligned dorsally and superiorly to a second end 504 that is aligned generally solely and inferiorly on the cuboid bone. The plate 500 may have an outer trapezoidal shape to match the general shape of the cuboid bone. For example, the first end 502 may be wider than the second end 504, and the first and second ends 502 and 504 may be substantially parallel to each other. The plate 500 includes an upper surface 506 and an opposite bottom surface 508 configured to contact the bone.

[0051] The cubic frame plate 500 defines a plurality of multiaxial holes 16 between its upper surface 506 and its bottom surface 508. Each hole 16 may be surrounded by a thin ring 510. One or more rings 510 may be connected together via columns 512 that form a lattice-like structure. For example, the cubic frame plate 500 may include eight multiaxial holes 16 connected to thin columns 512. Seven of the multiaxial holes 16 may be connected around a trapezoid, and an eighth hole 16 may be interconnected near the center of the plate 500. Larger openings or through spaces 514 may remain between the connections. Thinner configurations of the rings 510 and columns 512 along the through spaces 514 may allow the plate 500 to be molded or contoured. The network of rings 510 and columns 512 maintains plate strength and provides some flexibility to the plate 500. The cuboid plate 500 can be used on either the left or right foot.

[0052] Referring here to Figures 9A and 9B, a flower plate 600 according to one embodiment is shown. As shown in Figure 9A, the flower plate is contoured to be positioned laterally on the cubic bone. Due to its symmetrical design, the plate 600 looks the same in any direction. The plate 600 includes an upper surface 606 and an opposite bottom surface 608 configured to contact the bone. The flower plate 600 has petal-like or projection-like extensions 610 that radiate outward from a central circular region 612. Each projection extension 610 may begin with a narrower end connected to the central circular region 612 that radiates outward toward a rounded free end. In one embodiment, the flower plate 600 has six petal-like or projection-like extensions 610 that radiate outward from the central circular region 612. The central circular region 612 surrounds a single central multiaxial hole 16 located in the core of the plate 600. Each of the projections or extensions 610 also defines a multi-axis hole 16, for example, as a rim or ring surrounding the hole 16. The flower shape is configured to better conform to the shape of the cuboid bone and to fix the fracture site of the cuboid bone. The flower plate 600 can be used on the left or right foot.

[0053] Referring here to Figures 10A to 10E, a navicular plate 700 according to one embodiment is shown. As shown in Figure 10A, the navicular plate 700 is contoured to be positioned dorsally on the navicular bone. The navicular bone is one of the seven bones that make up the ankle and tarsal root of the foot. The navicular bone is located in the upper medial part of the metatarsal bone, adjacent to the cuboid bone, anterior to the head of the talus bone, and posterior to the cuneiform bones. As shown in Figure 10B, the navicular plate 700 has a body that extends from a first end or upper dorsal end 702 configured to be positioned on the upper part of the navicular bone to a second end or lower medial end 704 configured to be positioned toward the medial and / or bottom part of the navicular bone. The plate 700 includes an upper surface 706 and an opposite bottom surface 708 configured to be in contact with an adjacent bone. The navicular plate 700 defines a plurality of multiaxial holes 16 between its upper surface 706 and its bottom surface 708. Each hole 16 may be surrounded by a thin ring 710. One or more rings 710 may be connected together via supports 712. One or more larger openings or through spaces 714 may remain between some of the connections. The plate 700 may be divided into a dorsal lateral section 716, a main section 718, and an optional plantar bundle extension 720.

[0054] As shown in Figure 10C, the dorsal lateral section 716 of plate 700 may include a three-hole cluster that laterally wraps around the intrinsic shape of the scaphoid bone. The cluster of three multiaxial holes 16 is configured to position one or more screws 12 on the upper dorsal surface of the scaphoid bone. The three-hole cluster may be a symmetrical pattern at the vertices of a triangle having struts 712 that connect each ring 710 in a triangular shape. The triangle may be an equilateral triangle, and the rings 710 may be curved or contoured so that the axes of each hole 16 point together into the bone at their centers. The dorsal lateral section 716 may be bent or contoured to mimic the convex dorsal surface of the scaphoid bone. The dorsal lateral section 716 may be attached to the main section 718 using a single strut 706.

[0055] The main section 718 of plate 700 may include two rows of multiaxial holes 16 for fixing a fracture site of the scaphoid bone. The main section 718 may include a second central three-hole cluster connected to the dorsal-lateral section 716 by a single support 706. Similar to the dorsal-lateral section 716, the three-hole cluster may have a symmetrical pattern at the vertices of a triangle with support 712 connecting each ring 710 in a triangular shape. K-wire holes 18 may be positioned in the center between the clusters of multiaxial holes 16. A pair of support 712, which are of unequal length and define an open space 714 between them, separate the second central three-hole cluster from the third hole cluster. The open space 714 may have an irregular shape defined by the outside of the rings 710 and the support 712. In the case of the scaphoid plate 700, the third cluster forms the lower medial end 704 of plate 700. The third cluster may have a support 712 connecting each ring 710 together, and multi-axis holes 16 in an asymmetrical pattern having one or more K-wire holes 18 positioned within the cluster. For example, as best seen in Figure 10B, the third cluster may include an asymmetrical triangle of three multi-axis holes 16 with a single K-wire hole 18. When aligned with the second three-hole cluster, two rows of multi-axis holes 16 are available to receive one or more screws 12 on the medial surface of the scaphoid bone. The main section 718 may be curved or contoured to mimic the convex medial surface of the scaphoid bone, including the scaphoid tuberosity. The outer edge of the plate 700 may be scalloped or wavy to follow the hole pattern, minimizing potential soft tissue irritation.

[0056] Figure 10D shows a navicular plate 700' having a plantar fasciculus extension 720 according to one embodiment. The navicular plate 700' having a plantar fasciculus extension 720 is identical to the navicular plate 700, except that it includes a plantar extension 720 that encloses the plantar and medial aspects of the navicular bone. In the case of the navicular plate 700', the plantar extension 720 forms the lower plantar end 704 of the plate 700. As best seen in Figure 10E, the plantar extension 720 includes a fourth cluster of three multiaxial holes 16 configured to position one or more screws 12 on the inferior medial side of the navicular bone. The plantar extension 720, like the dorsal lateral section 716, includes a three-hole multiaxial cluster having a symmetrical pattern at the vertices of a triangle with supports 712 that connect each ring 710 in a triangular shape with a central K wire hole 18. The clusters may be arranged as an equilateral triangle, but the ring 710 may be curved or contoured so that the axes of each hole 16 point into the bone in different directions. The plantar extension 720 connects to the main section 718 and adds additional K-wire holes 18 to the main section 718. The plantar bundle extension 720 may be bent or contoured to mimic the convex plantar surface of the navicular bone. The navicular plates 700, 700' may be supplied in left and right configurations.

[0057] Referring here to Figures 11A and 11B, a utility plate 800 according to one embodiment is shown. The utility plate 800 is configured to fit multiple bones and / or span joints in the forefoot, midfoot, and hindfoot. For example, the utility plate 800 may be used to fix and / or fuse together the naviculo-cuneiform (NC) joint, the talo-navicular (TN) joint, the calcaneocuboid (CC) joint, or the tarsometatarsal (TMT) joint. Figure 11A shows the utility plate 800 positioned medially over the naviculo-cuneiform joint. Other fractures of bones in the foot or elsewhere may also be fixed using the utility plate 800.

[0058] As shown in Figure 11B, the utility plate 800 may have an H-shaped body extending from a first end 802 configured to be positioned on one bone (e.g., the navicular bone) to a second end 804 configured to be positioned on another bone (e.g., the cuneiform bone). The plate 800 includes an upper surface 806 and an opposite bottom surface 808 configured to be in contact with an adjacent bone. The H-shape may be formed by four projections or tabs 810 defining the four corners of the H-shape. In this case, the plate 800 may be oriented so that the tabs 810 generally point to the top / bottom or dorsal / sole of the bone. The ends 802, 804 may have a concave or inward curve between the tabs 810.

[0059] The utility plate 800 defines a plurality of multiaxial holes 16 between its upper surface 806 and bottom surface 808 to receive one or more screws 12 for fixing the plate 800 to bone. For example, one multiaxial hole 16 may be located within each projection or tab 810 that straddles the joint. The plate 800 may include multiaxial holes 16 and dynamic compression slots 14 aligned along the central axis between the first end 802 and the second end 804. The dynamic compression slots 14 are incorporated into the plate 800 in which compression through the plate 800 may be beneficial. For example, one multiaxial hole 16 may receive one screw 12 in one bone (e.g., the scaphoid bone), and the dynamic compression slots 14 may receive another screw 12 in an adjacent bone (e.g., the cuneiform bone). This allows for compression of bone fragments and / or the joint to reduce joint space, improve stability, and promote joint surface fusion, for example. The second pair of central multiaxial holes 16 may be aligned along a transverse axis horizontal to the central axis. These central holes 16 can generally be aligned with interosseous joints. However, it will be understood that the utility plate 800 may be oriented in any preferred manner for fixing joints and / or bones. The utility plate 800 may be supplied in small, medium, and large configurations that can be used on the left or right foot.

[0060] Referring here to Figures 12A and 12B, an H-plate 900 according to one embodiment is shown. Similar to the utility plate 800, the H-plate 900 may have an H-shaped body configured to span the joints of the forefoot, midfoot, or hindfoot. The H-plate 900 is configured to fit across multiple joints in the forefoot, midfoot, and hindfoot. For example, the H-plate 900 may be used to fix or fuse the navicular-cuneiform (NC) joint, the talus-navicular (TN) joint, the calcaneal-cuboid (CC) joint, or the tarsometatarsal (TMT) joint, or other joints or fracture sites. Figure 12A depicts an H-plate 900 positioned laterally over the calcaneal-cuboid (CC) joint.

[0061] As shown in Figure 12B, the H-plate 900 may have a solid H-shaped body extending from a first end 902 configured to be positioned on one bone (e.g., the calcaneus) to a second end 904 configured to be positioned on another bone (e.g., the cuboid). The plate 900 includes an upper surface 906 and an opposite bottom surface 908 configured to be in contact with an adjacent bone. The H-shape may be formed by four projections or tabs 910 defining the four corners of the H-shape. In this case, the plate 900 may be rotated and oriented so that the tabs 910 generally point proximal / distal and extend away from the joint. Each tab 910 may define a single multiaxial hole 16. The plate 900 may be shaped like an H to provide two threaded holes 16 per bone along the joint line. The threaded holes 16 may be positioned on the tabs 910 to allow for easier bending. This allows the surgeon to bend the screw holes to bones that may be located out of plane relative to adjacent bones across the joint line. This plate configuration can be offered in small, medium, and large sizes for the left and right feet.

[0062] Referring here to Figures 13A-13C, a tarsal sinus plate 1000 according to one embodiment is shown. The tarsal sinus plate 1000 is contoured to be positioned laterally on the calcaneus below the talus. The tarsal sinus approach is used for minimally invasive reduction and percutaneous fixation of displaced intra-articular calcaneal fractures. As shown in Figure 13A, the tarsal sinus plate 1000 is positioned on the lateral surface of the calcaneus just on the sole of the foot of the subtalar joint and follows the natural wave shape created by this joint line. The plate contour may conform to Gissane's critical angle (e.g., between approximately 130 and 145 degrees) to provide screw hole locations for rafting the subtalar joint surface to prevent collapse.

[0063] As shown in Figure 13B, the tarsal wave plate 1000 may have an elongated body extending from a first anterior end 1002 configured to be located on the anterior surface of the calcaneus to a second posterior end 1004 configured to be located on the lateral surface of the calcaneus below the subtalar joint. The plate 1000 includes an upper surface 1006 and an opposite bottom surface 1008 configured to be in contact with the adjacent bone. The tarsal wave plate 1000 may be divided into an anterior section 1010, a main body 1012, and a posterior section 1014.

[0064] As further highlighted in Figure 13C, the anterior portion 1010 of plate 1000 provides threaded holes 16 for any fracture site on the anterior surface of the calcaneus. The three anterior threaded holes 16 may be offset from the main body 1012 of plate 1000 by two tabs 1016 connecting them. The anterior portion 1010 may be separated from the main body 1012 by irregular spacing 1018. The tabs 1016 may be angled toward each other when connecting to the main body 1012. These tabs 1016 can be easily cut off if the anterior portion of the calcaneus is intact.

[0065] The main body 1012 may include, for example, a 3-hole multiaxial cluster having a symmetrical pattern. The axis of each hole 16 within the 3-hole cluster may be located at the vertices of an equilateral triangle. A central K-wire hole 18 may be located within the cluster. The posterior section 1014 may include a tail portion extending posteriorly from the main body 1012. The posterior section 1014 may include a plurality of multiaxial holes 16 following the wave of the subtalar joint. For example, five holes 16 may be provided in succession, mimicking the curvature of a wave or undulation. The troughs of the wave may begin in the main body 1012, and the ridges of the wave may peak toward the posterior end 1004. The outer edge of the plate 1000 may be scalloped or wavy to follow the hole pattern, minimizing potential soft tissue irritation. Additional K-wire holes 18 may be located, for example, between the posterior hole 16 and the adjacent hole 16, and between the 3-hole cluster and the next adjacent hole 16 along the posterior section 1014. The tarsal tunnel plate 1000 can be supplied in small and large sizes, with left and right configurations.

[0066] Referring here to Figures 14A to 14D, a tarsal sinus tongue plate 1000' according to one embodiment is shown. The tarsal sinus tongue plate 1000' is the same as the tarsal sinus wave plate 1000, but with the addition of a posterior extension 1020 and a plantar offset extension 1022. The tarsal sinus tongue plate 1000' is contoured to be positioned laterally on the calcaneus below the talus and subtalar joint. Similar to the tarsal sinus wave plate 1000, the tarsal sinus tongue plate 1000' is positioned plantarly on the subtalar joint and rafts the subtalar joint.

[0067] The tarsal sinus tongue plate 1000' includes an anterior section 1010, a main body 1012, and a posterior section 1014. The anterior section 1010 includes the same three-hole anterior portion 1010 which can be easily cut and removed. The main body 1012 includes a three-hole cluster, and the posterior section 1014 includes waves that follow the contour of the subtalar joint. As best seen in Figure 14C, the posterior extension 1020 extends posteriorly from the free end of the posterior section 1014. The posterior extension 1020 may include a first linear continuity of the posterior section 1014. The posterior extension 1020 may include, for example, a series of multiaxial holes 16 aligned in a linear arrangement. The outer edge of the posterior extension 1020 may be scalloped or wavy to follow the hole pattern. The multi-axis holes 16 within the posterior extension 1020 can act as posteriorly extending rafting screw holes to capture bone fragments that may have been displaced in the tongue-type fracture site of the calcaneus.

[0068] As further highlighted in Figure 14D, the plantar offset extension 1022 may extend posteriorly and plantarly from the free end of the posterior section 1014. The plantar offset extension 1022 may include a second shaped continuity of the posterior section 1014 angled with respect to the posterior extension 1020. The plantar offset extension 1022 may have a solid linear body terminating in a three-hole cluster. The three-hole cluster may define holes 16 having axes of a symmetrical pattern at the vertices of a triangle. Additional extensions 1020, 1022 may create another three-hole cluster at the intersection of the posterior section 1014 and the extensions 1020, 1022. One or more K-wire holes 18 may be positioned along the length of the extensions 1020, 1022. The posterior plantar offset 1022 defines a screw hole 16 capable of receiving a screw 12 configured to capture a bone fragment that can be displaced in the plantar region within the calcaneus. Either or both of the plate extensions 1020, 1022 may be cut off by the surgeon if they are not needed. The tarsal sinus tongue plate 1000' may be supplied in small and large sizes, with left and right configurations.

[0069] Referring here to Figures 15A and 15B, a pericalcaneal plate 1100 according to one embodiment is shown. As shown in Figure 15A, the pericalcaneal plate 1100 is contoured to be positioned laterally on the calcaneus. The pericalcaneal plate 1100 may be used in severe fractures of the calcaneus where multiple fracture sites and displaced bone fragments are present. The pericalcaneal plate 1100 is configured to align around the calcaneus to screw into the cortical bone for structural stability and to join the calcaneus together to be as close as possible to its original shape. The pericalcaneal plate 1100 may act as a backboard to hold the calcaneal bone fragments until the bone begins to heal.

[0070] The calcaneal periplate 1100 extends from a first anterior end 1002 configured to be positioned laterally on the anterior surface of the calcaneus to a second posterior end 1004 configured to be positioned laterally on the posterior surface of the calcaneus. The plate 1100 includes an upper surface 1106 and an opposite bottom surface 1108 configured to be in contact with the bone. The calcaneal periplate 1100 defines a plurality of multiaxial holes 16 between the upper surface 1106 and the bottom surface 1108. Each multiaxial hole 16 may be surrounded by a ring 1110. One or more rings 1110 may be connected together via supports 1112 that form a lattice structure. Larger openings or through spaces 1114 may remain between the connections. In one embodiment, the periphery of 13 periphery rings 1110 may be connected together with the periphery supports 1112. The periphery may mimic the outer surface of the calcaneus, for example, having a smaller quadrilateral shape at the anterior end 1102 and a larger, more rounded shape at the posterior end 1104. In exemplary embodiments, the periphery ring 1110 conforms to the periphery of the calcaneus so that the screw 12 can be directly inserted into the cortical bone of the calcaneus, ensuring structural stability.

[0071] Additional screw holes 16 and internal supports 112 may be located internally around the periphery of the plate 1100. In one embodiment, three internal rings 1110 may be connected together, and having a surrounding periphery ring 1110. The internal rings 1110 and internal supports 112 may provide cross bracing to maintain plate strength and provide some flexibility to the plate 1100. The internal holes 16 provide additional anchoring points for displaced bone fragments and surfaces for pulling the bone. The calcaneal periplate 1100 may be available in small, medium, and large sizes, as well as in left and right configurations.

[0072] Referring here to Figures 16A and 16B, a rafting periphery plate 1200 according to one embodiment is shown. The rafting periphery plate 1200 provides a hybrid approach that rafts the subtalar joint like the tarsal joint plate 1000 and provides periphery to the calcaneus like the calcaneal periphery plate 1100. This gives surgeons options for fixing severe calcaneal fractures circumferentially while providing a choice of rafting screws and support for the subtalar joint. The rafting periphery plate 1200 also features a strut that helps contain displaced bone fragments within the fracture site. As shown in Figure 16A, the rafting periphery plate 1200 is positioned laterally on the calcaneus with rafting and periphery screw hole locations.

[0073] Referring here to Figure 16B, the rafting periphery plate 1200 extends from a first anterior end 1202 configured to be positioned laterally on the anterior surface of the calcaneus to a second posterior end 1204 configured to be positioned laterally on the posterior surface of the calcaneus below the subtalar joint. The plate 1200 includes an upper surface 1206 and an opposite bottom surface 1208 configured to contact the adjacent bone. The components of the rafting periphery plate 1200 may include an anterior section 1210, a main body 1212, a posterior section 1214, a posterior extension 1220, a plantar offset extension 1222, a cross member 1224, and a posterior connecting extension 1226.

[0074] Similar to the tarsal wave plate 1000, the anterior section 1210 of plate 1200 may include three anterior threaded holes 16 offset from the main body 1212 of plate 1200. A pair of angled tabs 1216 may connect the three anterior threaded holes 16 to the main body 1212, and since the anterior portion of the calcaneus is intact, that portion of plate 1200 can be easily cut off if it is not needed. The main body 1212 of plate 1200 may include a three-hole multiaxial cluster having a symmetrical pattern with, for example, a central K-wire hole 18. The axis of each hole 16 in the three-hole cluster may be positioned at the vertices of an equilateral triangle. The posterior section 1214 may include a wavy tail extending posteriorly from the main body 1212. The posterior section 1214 may define a plurality of multiaxial holes 16 following the wave of the subtalar joint.

[0075] Similar to the tarsal sinus tongue plate 1000', the plate 1200 includes a posterior extension 1220 and a plantar offset extension 1222. The posterior extension 1220 extends posteriorly from the free end of the posterior section 1214. The posterior extension 1220 may include a first linear continuity of the posterior section 1214. The posterior extension 1220 may include a series of multiaxial holes 16 aligned, for example, in a linear arrangement. The multiaxial holes 16 within the posterior extension 1220 may act as rafting screw holes extending posteriorly to capture bone fragments that may have been displaced during a tongue-type fracture of the calcaneus.

[0076] The plantar offset extension 1222 may extend posteriorly and plantarly from the free end of the posterior section 1214. The plantar offset extension 1222 may include a second linear continuity of the posterior section 1214 angled with respect to the posterior extension 1220. The plantar offset extension 1222 may have a solid linear body terminating in a multi-axis hole 16. The posterior plantar offset 1222 defines a screw hole 16 that can receive a screw 12 configured to capture a bone fragment that can be displaced in the plantar region within the calcaneus.

[0077] The sole offset extension 1222 is connected to the rear extension 1220 by a cross member 1224. The cross member 1224 may be a linear beam connecting the free end of the sole offset extension 1222 to the free end of the rear extension 1220. Multiaxial holes 16 may be provided at the corners or ends of the cross member 1224. Additional multiaxial holes 16 may be provided along the length of the cross member 1224. Three holes 16 in the cross beam 1224 may be aligned in a straight line.

[0078] The rear extension 1226 can connect the main body 1212 to the sole offset extension 1222 and the cross member 1224. The rear extension 1226 may be a linear beam connecting the main body 1212 to the free end of the sole offset extension 1222. The rear extension 1226 may be aligned substantially parallel to the rear extension 1220. A series of multi-axis holes 16 defined through the rear extension 1216 may be aligned in a straight line. For example, a pair of holes 16 may be positioned toward the main body 1212, and another pair of holes 16 may be positioned together with the sole offset extension 1222.

[0079] The posterior section 1214, posterior extension 1220, cross member 1224, and posterior extension 1226 of plate 1200 may form a substantially rectangular outer shape. A planar offset extension 1222 may be a diagonal dividing the rectangle into two triangles with an internally open space 1228. The posterior section 1214 and posterior extension 1220 provide a row of rafting screw options below the subtalar joint, which may act as a raft for supporting the subtalar joint shard. The numerous screw options around the implant 1200 target the cortical bone around the calcaneus, which improves structural stability. Screw holes 16 located medially and at the bottom of plate 1200 provide additional fixation points for displaced shards that may be displaced in the plantar. The rafting periphery plate 1200 may be available in small and large sizes as well as in left and right configurations.

[0080] Referring here to Figures 17A and 17B, a talus T-plate 1300 according to one embodiment is shown. As shown in Figure 17A, the talus T-plate is contoured to be positioned laterally on the neck of the talus. Most talus fractures occur in the neck, and the plate 1300 is configured to provide fixation to anterior and posterior fracture fragments. Referring here to Figure 17B, the talus T-plate 1300 extends from a first anterior end 1302 configured to be positioned laterally on the neck of the talus to a second posterior end 1304 configured to be positioned laterally on the body of the talus. The plate 1300 includes an upper surface 1306 and an opposite bottom surface 1308 configured to contact the adjacent bone.

[0081] The talus T-plate 1300 has a body having a substantially T-shaped outline. The T-plate 1300 has an elongated posterior portion or leg 1310 and a transverse anterior crossing portion 1312. The leg 1310 may be bent or angled relative to the crossing portion 1312. The posterior portion 1310 or leg of the T-shape may be contoured to mimic the natural anatomical structure of the talus. The anterior portion 1312 or upper part of the T-shape may be contoured to slightly wrap around the neck. The transverse crossing portion 1312 may include one or more wings or extensions extending outward from the leg 1310. The crossing portion 1312 may be substantially perpendicular to the leg 1310 of the plate 1300. The plate 1300 may include a plurality of multiaxial holes 16 and / or K-wire holes 18. The outer edge of plate 1300 may be scalloped or wavy to follow the perforation pattern, minimizing potential soft tissue irritation. The talar T-plate 1300 may be available in various lengths with various perforation options. The talar T-plate 1300 may be supplied in both left and right configurations.

[0082] Referring here to Figures 18A and 18B, a talar L-plate 1300' according to one embodiment is shown. The talar L-plate 1300' is identical to the talar T-plate, except that one wing or extension of the intersecting portion 1312 is removed. As shown in Figure 18A, the talar L-plate 1300' is contoured to be positioned laterally on the neck of the talus. Similar to the talar T-plate 1300, the L-plate 1300' provides fixation on the anterior and posterior fracture fragments. Figure 18B shows a talar L-plate 1300' having a substantially L-shaped outline. The L-plate 1300' provides fewer anterior thread holes when additional fixation is not needed or when the T-plate 1300 is too large to fit the anatomical structure. The L-plate 1300' may be provided in both left and right configurations.

[0083] Referring here to Figures 19A and 19B, a talus butterfly plate 1400 according to one embodiment is shown. As shown in Figure 19A, the talus butterfly plate 1400 may be contoured to be positioned laterally on the neck of the talus. The talus butterfly plate 1400 is configured to provide fixation to anterior and posterior fracture fragments and provides two rows of threaded holes for a more stable construct. As shown in Figure 19B, the talus butterfly plate 1400 extends from a first anterior end 1402 configured to be positioned laterally on the neck of the talus to a second posterior end 1404 configured to be positioned laterally on the body of the talus. The plate 1400 includes an upper surface 1406 and an opposite bottom surface 1408 configured to contact the adjacent bone.

[0084] The talus butterfly plate 1400 may have a symmetrical butterfly-like shape with opposing wing portions 1410. The wing portions 1410 may include projections defining each multiaxial hole 16. For example, each wing portion 1410 may have an upper projection and a lower projection. The upper projection may be slightly larger than the lower projection. One wing portion 1410 with two holes 16 may be provided at the anterior end 1402, and a mirror-image wing portion 1410 with two holes 16 may be provided at the posterior end 1404. The wing portions 1410 may be mirror images and may be bent around a centerline. The outer edge of the plate 1400 may be scalloped or wavy to follow an outer hole pattern. A central K-wire hole 18 may be provided through the plate 1400. The talus butterfly plate 1400 may be used on the left or right foot and may be provided in small and large configurations. As shown in Figure 20, the larger talar butterfly plate 1400' may have an extended wing or projection and provide four additional holes for fixation.

[0085] Referring here to Figure 21, a series of repair plates 10' can be used for fixing the anatomical structure of bone after anatomical correction. Plate 10' can be used in the treatment of various fracture sites of the foot in the forefoot, midfoot, and hindfoot. Nine different plate types in the treatment of various repairs include (a) metatarsophalangeal (MTP) plates, (b) low-profile MTP plates, (c) Rapidus plates, (d) tarsometatarsal (TMT) plates, (e) navicular-cuneiform (NC) plates, (f) medial column plates, (g) Evans osteotomy wedge plates, (h) Cotton opening wedge plates, and (i) calcaneal slide plates.

[0086] Referring here to Figures 22A and 22B, a metatarsophalangeal (MTP) plate 1500 according to one embodiment is shown. As shown in Figure 22A, the MTP plate 1500 is contoured to be positioned on the dorsal surface of the first MTP joint. The MTP plate 1500 has a body that extends from a first end or proximal end 1502 configured to be positioned on the first metatarsal bone to a second end or distal end 1504 configured to be positioned on the first proximal phalanx. The plate 1500 includes an upper surface 1506 and an opposite bottom surface 1508 configured to be in contact with the adjacent bone. The plate 1500 may include three sections: a proximal section 1510, a bridge section 1512, and a distal section 1514.

[0087] As shown in Figure 22B, the proximal section 1510 defines at least two holes 16 proximally for fixation to the metatarsal bones. The proximal section 1510 further defines compression holes 14 for achieving compression. The plate 1500 also defines a K-wire slot 20 for achieving further compression with a guidewire or K-wire. The bridge section 1512 may be a linear beam extending over the MTP joint. The distal section 1514 defines three distal holes 16 for fixation to the phalanges. A K-wire hole 18 may also be provided distally. The compression slot 14, K-wire slot 20, K-wire holes 18, and the most distal multiaxial hole 16 may be aligned along the central longitudinal axis of the plate 1500. The outer edges of the proximal section 1510 and the distal section 1514 may be scalloped or wavy to follow the hole pattern. Plate 1500 may include one or more markings 1520, indicators, notches, radiopaque markers, etc., indicating the general location of the joint. For example, a single line 1520 may indicate the location of the MTP joint across the upper surface 1506 of plate 1500. This marking 1520 may help the surgeon to optimally fit plate 1500 to the joint. MTP plates 1500 may be left / right specific in small, medium, large, extra-large, and modification options, providing more holes and longer bridge lengths to fit larger sections of the population.

[0088] Referring here to Figures 23A and 23B, a metatarsophalangeal (MTP) narrow plate 1500' according to one embodiment is shown. The MTP narrow plate 1500' is identical to the MTP plate 1500, except that it is a narrower version of the MTP plate, having only two screw holes distally for a lower profile over the phalanges. As shown in Figure 23A, the MTP narrow plate 1500' is contoured to be positioned on the dorsal surface of the first MTP joint. Similar to the MTP plate 1500, the proximal end 1510 of the plate 1500' includes two multiaxial locking holes 16, one compression slot 14, and a K-wire slot 20 to assist in compressing the joint. The distal end 1504 includes a linear extension separate from the bridge section 1512. The distal section 1514 defines two multiaxial locking holes 16 for fixation to the phalanges. The K-wire hole 18 can be positioned between the distal holes 16. The width of the distal section 1514 may be the same as that of the bridge section 1512, thereby forming a narrow and low profile.

[0089] Referring here to Figures 24A and 24B, a Rapidus plate 1600 according to one embodiment is shown. As shown in Figure 24A, the Rapidus plate 1600 is contoured to be positioned on the medial surface of the first tarsometatarsal joint. The Rapidus plate 1600 has a body that extends from a first end or proximal end 1602 configured to be positioned on the medial cuneiform bone to a second end or distal end 1604 configured to be positioned on the first metatarsal bone. The plate 1600 includes an upper surface 1606 and an opposite bottom surface 1608 configured to be in contact with the adjacent bone. The plate 1600 may include three sections: a proximal section 1610, a bridge section 1612, and a distal section 1614.

[0090] The proximal section 1610 includes multiaxial locking holes 16 configured to fix the plate 1600 to the medial cuneiform bone. The proximal section 1610 may include an upward projection or tab. The bridge section 1612 is angled or inclined downward toward the distal end 1604. The distal section 1614 includes multiaxial locking holes 16 configured to fix the plate 1600 to the first metatarsal bone. The distal section 1614 may include a downward projection or tab. Compression slots 14 may be provided along the inclined central axis of the plate 1600 toward the distal end 1604. In one embodiment, the Rapidus plate 1600 includes four multiaxial locking holes 16, two for the metatarsals and two for the cuneiform bones, and one compression slot 14 is located laterally to the metatarsal bone. In another embodiment, a more robust plate offering may include six multiaxial holes 16 for receiving screws 12, three located within the metatarsal bones and three within the cuneiform bones. The plate 1600 may be left / right specific, with short and long options, where the bridge length varies proximal and distally.

As shown in Figure 25A, the TMT plate 1700 is contoured to be positioned dorsally on the second tarsometatarsal (TMT) joint. The TMT plate 1700 may be configured to fit the first, second, and third TMT joints or Lisfranc joints. The TMT plate 1700 has an elongated body extending from a first end or proximal end 1702 configured to be positioned on the cuneiform bone to a second end or distal end 1704 configured to be positioned on the metatarsal bone. The plate 1700 includes an upper surface 1706 and an opposite bottom surface 1708 configured to be in contact with the adjacent bone. The plate 1700 may include three sections: a proximal section 1710, a bridge section 1712, and a distal section 1714.

[0092] The head of the proximal section 1710 or plate 1700 may be provided with a plurality of threaded hole configurations, including left-facing and right-facing T, L, oblique T, oblique L, and claw-shaped holes. In the shown embodiment, two multi-axis holes 16 are defined off-axis in the proximal section 1710, and K-wire holes 18 are provided between them. The bridge section 1712 may be a linear solid beam spanning the TMT joint. The distal section 1714 may include two or four multi-axis holes 16 with compression slots 14, thereby providing compression to the joint. The holes 16 and slots 14 may be aligned with the central longitudinal axis of plate 1700. In the shown embodiment, the compression slots 14 are positioned between the holes 16, and two K-wire holes 18 are positioned between the slots 14 and adjacent holes 16. It will be understood that plate 1700 may have any preferred arrangement of holes 16 for optimal mounting. Plate 1700 may include one or more markings 1720 or other indicators to indicate the general location of the joint. For example, a pair of parallel lines 1720 may indicate the location of the TMT joint across the upper surface 1706 of plate 1700. These markings 1720 may help the surgeon to optimally align plate 1700 with the joint.

[0093] Referring here to Figure 26, a scaphoid-cuneiform (NC) plate 1800 according to one embodiment is shown. The NC fusion plate 1800 is contoured to cover the scaphoid-cuneiform (NC) joint and be positioned dorsally. The NC plate 1800 is configured to stabilize the medial and central cuneiform bones relative to the scaphoid bone, and also allows inter-scaphoid screws 12 to be fed through the plate 1800 through the use of recessed holes 22.

[0094] The NC plate 1800 has an elongated body extending from a first end or proximal end 1802 configured to be located on the scaphoid bone to a second end or distal end 1804 configured to be located on the cuneiform bone. The plate 1800 includes an upper surface 1806 and an opposite bottom surface 1808 configured to be in contact with the adjacent bone. The plate 1800 may include three sections: a proximal section 1810, a bridge section 1812, and a distal section 1814.

[0095] The proximal section 1810 includes a pair of multiaxial locking holes 16 configured to fix the plate 1800 to the dorsal side of the scaphoid bone. The proximal holes 16 may be located within a projection or ear at the proximal end 1802 of the plate 1800. The proximal section 1810 may further define a recessed hole 22. The recessed hole 22 may be a multiaxial locking hole that functions as a proximal cortex for a lag screw. The recessed hole 22 may be located along the central axis of the plate 1800, but the axis of the hole may be angled so that the lag screw 12 is inserted distally. The recessed hole 22 is located in the plate 1800, and the surgeon may use a reamer to create a pocket in the bone to fit the plate 1800.

[0096] The bridge section 1812 may include a solid section that is angled or inclined downward toward the distal end 1804. One or more K-wire holes 18 may also be aligned along the central axis of the plate 1800. The distal section 1814 includes a multiaxial locking hole 16 configured to fix the plate 1800 dorsally to the cuneiform bone. The distal hole 16 may be located within a projection or ear portion of the distal end 1804 of the plate 1800. One of the distal projections may be extended toward the other projection. The NC plate 1800 may be provided in both left and right configurations.

[0097] Referring here to Figures 27A and 27B, a medial post plate 1900 according to one embodiment is shown. The medial post plate 1900 extends from the medial surface of the talus to the first metatarsal bone. As shown in Figure 27A, the medial post plate 1900 is contoured to bridge across the metatarsal region, covering the talus, navicular bone, medial cuneiform bone, and first metatarsal bone. The medial post plate 1900 has a rigid structure for holding the bones in place, while allowing at least three screws to be positioned in each of these bones.

[0098] The medial column plate 1900 has an elongated body extending from a first end or proximal end 1902 configured to be located on the talus to a second end or distal end 1904 configured to be located on the metatarsal bones. The plate 1900 includes an upper surface 1906 and an opposite bottom surface 1908 configured to be in contact with the adjacent bone. The plate 1900 may include four sections: a proximal talus section 1910, a navicular section 1912, a cuneiform section 1914, and a distal metatarsal section 1916.

[0099] The proximal talus section 1910 includes three multiaxial holes 16 in the nearest end 1902 of the plate 1900, configured to fix a screw 12 to the talus. One of the multiaxial holes 16 in the proximal talus section 1910 may protrude dorsally via a tab 1918. The scaphoid section 1912 includes an arrangement of three multiaxial holes 16 configured to fix a screw 12 to the scaphoid bone. The multiaxial holes 16 may be arranged in a triangular pattern having a first K-wire slot 22 configured to achieve compression by a guide wire or K-wire. The cuneiform section 1914 includes a triangular arrangement of three multiaxial holes 16 configured to fix a screw 12 to a cuneiform bone, having a second K-wire slot 22 for receiving a K-wire for further compression. The first and second K-wire slots 22 may be centrally located along the longitudinal axis of the plate 1900.

[0100] The distal metatarsal section 1916 includes a plurality of multiaxial holes 16 configured to fix screws 12 within the metatarsal bone. For example, six multiaxial holes 16 are arranged in two rows: two dorsally and four plantarly. However, it will be understood that any preferred arrangement of holes 16 may be used to fix the metatarsal bone. K-wire holes 18 may be provided in the distal metatarsal section 1916 to provide guides or additional fixation points for the plate 1900. The plate 1900 may include one or more markings 1920 or other indicators to indicate the general location of joints. For example, a pair of parallel stripes 1920 may indicate the location of the tarsometatarsal joint across the upper surface 1906 of the plate 1900. These markings 1920 may help the surgeon to optimally align the plate 1900 with the tarsometatarsal joint. It will be understood that additional markings may be added for other joints as well.

[0101] Referring here to Figures 28A and 28B, an Evans osteotomy wedge plate 2000 according to one embodiment is shown. As best seen in Figure 28A, the Evans osteotomy wedge plate 2000 is configured to fit a calcaneal osteotomy. The Evans procedure may include creating an osteotomy on the lateral surface of the calcaneus and inserting a wedge 2012 to lengthen the lateral column of the foot. The process of inserting the wedge 2012 fixes the valgus deformity by mediating the posterior portion of the calcaneus at the osteotomy site. The plate portion is positioned above the osteotomy site and fixes the implant to the calcaneus.

[0102] As shown in Figure 28B, the Evans osteotomy wedge plate 2000 extends from a first proximal end 2002 configured to be located proximal to the calcaneus to a second distal end 2004 configured to be located distal to the calcaneus. The plate 2000 includes an upper surface 2006 and an opposite bottom surface 2008 configured to contact the adjacent bone. The plate 2000 may have a symmetrical dogbone-like shape, wider at both ends and narrower in the center. The ends include projections 2010, each defining one multiaxial hole 16. The projections 2010 may be curved or contoured to mimic the shape of the calcaneus. The outer edges of the projections 2010 may be rounded to follow the hole pattern. A stationary wedge 2012 protrudes from the bottom surface 2008 and is configured to fit into the osteotomy cut into the calcaneus. The wedge 2012 includes one or more inclined planes or surfaces configured to spread the bone at a certain angle. The plate 2000 can then be fixed to both sides of the osteotomy with two multi-axis screws 12. The plate 2000 may include, for example, a bone graft window 2014 that penetrates the surface of the plate 2000 and enters the wedge 2012, which may be filled before or after implantation.

[0103] Referring here to Figures 29A and 29B, a Cotton opening wedge plate 2100 according to one embodiment is shown. As best seen in Figure 29A, the Cotton opening wedge plate 2100 is configured to fit a medial cuneiform osteotomy. The Cotton procedure may include creating an osteotomy on the medial surface of the cuneiform bone and inserting a wedge 2112 to lengthen the upper part of the medial cuneiform bone and create an arch in the foot. This procedure is generally performed to help correct a condition of arch collapse or flatfoot. The plate portion is located on the dorsomedial surface of the medial cuneiform bone at the osteotomy site and fixes the implant to the cuneiform bone.

[0104] As shown in Figure 29B, the cotton opening wedge plate 2100 extends from a first proximal end 2102 configured to be located proximal to the wedge bone to a second distal end 2104 configured to be located distal to the wedge bone. The plate 2100 includes an upper surface 2106 and an opposite bottom surface 2108 configured to be in contact with the adjacent bone. The plate 2100 may have a symmetrical shape with projections 2110 at four corners, each defining one multiaxial hole 16. The plate 2100 may be substantially flat or planar. The outer edges of the projections 2110 may be rounded or contoured to follow the hole pattern. A stationary wedge 2112 protrudes from the bottom surface 2108 and is configured to fit into the osteotomy cut into the wedge bone. The wedge 2112 includes one or more inclined planes or surfaces configured to spread the bone at a certain angle. The plate 2100 can then be fixed to both sides of the osteotomy with two multi-axis screws 12. The plate 2100 may include, for example, a central bone graft window 2114 that penetrates the surface of the plate 2100 and enters the wedge 2112, which can be filled before or after implantation.

[0105] Referring here to Figures 30A and 30B, a calcaneal slide plate 2200 according to one embodiment is shown. As best seen in Figure 30A, the calcaneal slide plate 2200 is positioned on the lateral surface of the calcaneal osteotomy site. The calcaneal slide plate 2200 is configured to fix the calcaneal osteotomy after being moved to correct the deformity. A calcaneal slide osteotomy alters the alignment of the calcaneus or heel bone. This procedure involves cutting the calcaneus, adjusting or shifting the posterior part of the bone, and stabilizing the bone with an implant. A calcaneal slide osteotomy may be used to correct problems such as flat feet or abnormally high arches.

[0106] As shown in Figure 30B, the calcaneal slide plate 2200 extends from a first proximal end 2202 configured to be located proximal to the calcaneus to a second distal end 2104 configured to be located distal to the calcaneus. The plate 2200 includes an upper surface 2206 and an opposite bottom surface 2208 configured to be in contact with the adjacent bone. The plate 2200 may include a plate portion having a projection 2210 defining a multiaxial hole 16 and a wedge portion 2212 defining the multiaxial hole 16. The plate portion and the wedge portion 2212 may be bent or angled relative to each other. The wedge portion 2212 may include one or more inclined planes or surfaces. The wedge portion 2212 may be configured to project laterally. The plate 2200 may be available in several different sizes to account for slide compensation based on the height of the implant. Plate 2200 allows two multi-axis screws 12 to be placed on either side of the osteotomy site. The screws 12 fix the two halves of the calcaneus so that the calcaneus can heal in the corrected position.

[0107] The foot plate assembly 10 includes a comprehensive proposal for treating a wide range of fracture patterns in the forefoot, midfoot, and hindfoot. Plate 10 can be used for both final fixation, permanent fixation, and temporary or supplemental fixation, according to other systems. Specific plate configurations can accommodate multiple fracture patterns. Plates can be cut and contoured to accommodate extreme patient anatomical structures. A wide range of screw and plate sizes can accommodate multiple anatomical structures and regions.
