Description

BACKGROUND

[0001] Fractures along the clavicle are fairly common and can occur along any portion of the clavicle. Current implants are designed to treat only certain portions of the clavicle. For example, there is no practical implant that is specifically designed to treat medial clavicle fractures. Additionally, in some cases, existing clavicle plates can not fit well with a patient’s specific anatomy, resulting in soft tissue irritation, which can lead to pain and / or premature removal of the plate. SUMMARY

[0002] The present disclosure is directed to a medial plate for treating medial fractures of the clavicle, the medial plate comprising a plate body sized and shaped to be positioned along a medial portion of the clavicle. The plate body comprises a longitudinal component extending from a first end to a second end along a longitudinal axis and an extension portion extending from the second end away from the longitudinal axis, the second end configured to be mounted over a medial head of the clavicle, the plate body defining via an upper surface and a lower surface, the upper surface facing away from the clavicle in an operative position, the lower surface facing toward the clavicle in the operative position. A first set of variable angle holes extend through the extension portion and a portion of the longitudinal component including the second end of the longitudinal component, each of the first set of variable angle holes extending through the plate body from the upper surface to the lower surface along a central axis such that a bone screw can be inserted through each of the first set of variable angle holes at a user-selected angle relative to the central axis of the variable angle hole. A plurality of combination holes extend through the longitudinal component transverse to the first set of variable angle holes, each of the plurality of combination holes comprising a first portion configured to receive a bone screw at a user-selected angle relative to a central axis thereof and a second portion configured to receive a compression screw.

[0003] The present disclosure is also directed to a method for treating a clavicle fracture, the method comprising identifying a location of the fracture relative to one of five segments of the clavicle to be treated, and determining a plate type for treating the fracture based on the identified location of the fracture.

[0033] ​​​​​​​​​​​The present disclosure can be understood with reference to the following description and drawings, wherein like reference numerals refer to like elements. The present embodiments relate to treating clavicle fractures, and in particular to a clavicle bone engagement system for treating distal (or lateral), midshaft, and medial clavicle fractures, malunions, and nonunions. Exemplary embodiments describe a fracture-specific plate system comprising a plurality of plates, each plate designed to address a specific fracture site. The size, shape, and configuration of each bone plate is specifically set to treat a particular portion of the clavicle, and there are multiple shapes available for use to fit the clavicle in different sizes based on the patient’s size (e.g., height). For example, a larger sized patient will require a longer and / or larger plate than a proportionally smaller sized patient. Those skilled in the art will appreciate that the terms distal and medial as used herein refer to the distal and medial directions, respectively, with respect to the clavicle.

[0034] As Figure 1 shown, according to the clavicle bone engagement system of the present disclosure, the clavicle can be divided into a plurality of segments such that a fracture along each of the segments can be treated using at least one plate provided by the system. In other words, each plate type is designed to address a specific fracture site. The clavicle extends from a distal end to a medial end, and from the distal end to the medial end can be divided into five segments of equal length (designated as Segment 1 - Segment 5). A fracture occurring in the first segment (i.e., the distal most segment of the bone) can be treated using one of the lateral plates 100-300, while a fracture occurring in the fifth segment (i.e., the most medial segment) can be treated using the medial plate 800. A fracture occurring in the third segment (i.e., the middle portion of the clavicle) can be treated using one of the shaft plates 400-700.

[0035] However, depending on the specific location of the fracture, either a lateral plate 100-300 or a medial plate 800 and a shaft plate 400-700 can be used to treat the second and fourth segments. For example, depending on the location of the fracture, either a lateral plate 100-300 or a shaft plate 400-700 can be used to treat a fracture occurring in the second segment. Depending on the location of the fracture, either a shaft plate 400-700 or a medial plate 800 can be used to treat a fracture occurring in the fourth segment. These specialized plate solutions have multiple shapes available for use such that the plate that best fits the patient’s specific anatomy can be selected.

[0036] As Figure 2As shown, an exemplary implementation compiles and analyzes a database of clavicles from patients of different body sizes to determine the optimal size, shape, and configuration of the lateral, axial, and medial plates described herein. Specifically, in one implementation, bone sizes are categorized into three classes, broadly designated as small bones, medium bones, and large bones. Small bones include clavicles less than 134 mm in length. Medium bones include clavicles ranging in length from 134 mm to 155 mm. Large bones include clavicles longer than 155 mm. Using the bone sizes from the compiled data, polynomial equations are employed to determine the optimal transverse and coronal curvatures, as well as the plate length, for altering the plate shape to best fit patients of different body sizes.

[0037] The side plates 100-300 of the system according to this disclosure may be available in, for example, three sizes, adapted to variations in the length and curvature of the clavicle based on the patient's body size. For example, a smaller patient will have a smaller clavicle with a smaller size but greater curvature compared to a larger patient. In one embodiment, the coronal curvature and / or transverse curvature and / or the length of each side plate in the side plates 100-300 may be correlated with the patient's height. The dimensions of the side plates 100-300, as described below, have been determined based on analysis of the bones of patients of various sizes. A physician or other user may select one of the three side plates 100-300 based on the patient's size and the location of any fracture along the distal portion of the clavicle.

[0038] like Figures 3 to 9 As shown, a first side plate 100 according to an exemplary embodiment of this disclosure includes a plate body 102 extending from a first end 104 to a second end 106, and includes an upper surface 108 and an inner surface 110 facing the bone. When the first side plate 100 is in the operating position, the upper surface faces away from the clavicle, and the inner surface facing the bone faces the clavicle. In the operating position, the first end 104 is positioned above the distal end of the clavicle such that the plate body 102 extends along the upper surface of the clavicle, along at least a portion of its length corresponding to a second segment of the clavicle and the length of the first segment, as described above. Figure 1 As shown, the second end 106 extends toward the medial end of the clavicle. The first side plate 100 is the smallest of the three side plates 100-300 described herein, and the user can select the first side plate to treat simple fractures of the very distal clavicle. As will be described in further detail below, the first side plate 100 includes a plurality of variable-angle holes 112, 114 that extend through a portion of the plate body 102 to select a configuration for optimal treatment of distal clavicle fractures.

[0039] The plate 102 extends longitudinally along a curve corresponding to the curve along the distal portion of the clavicle and has a decreasing width from a first end 104 to a second end 106 (i.e., the distance between the longitudinal sides 132 of the plate 102). The plate 102 may also be curved to extend longitudinally around the clavicle. In one embodiment, the length of the plate 102 ranges from about 40 mm to 70 mm. In another embodiment, the length of the plate 102 ranges from about 45 mm to 65 mm, and in a more specific embodiment, the plate length ranges from about 50 mm to 60 mm. In one embodiment, the plate 102 includes a radius of curvature in the range of 40 mm to 50 mm, and in a particular embodiment, includes a radius of curvature of about 44 mm. According to this embodiment, the width of the plate 102 ranges from about 10 mm to 20 mm at the first end 104, and in a more specific embodiment, its width ranges from about 15 mm to 16 mm. In one embodiment, the first end 104 is curved to extend around the distal head of the clavicle. The second end 106 may include an inclined surface 120 connecting the upper surface 108 to the lower surface 110, wherein the inclined surface 120 is angled to reduce the profile of the plate 102 at the second end 106, thereby facilitating percutaneous insertion. In one embodiment, the inclined surface 120 may extend at an angle between 10 degrees and 30 degrees. In one example, the inclined surface 120 may extend at an angle of approximately 20 degrees relative to the lower surface 110.

[0040] In one embodiment, the first side plate 100 includes a plurality of variable-angle holes 112 extending through the plate body 102 near a first portion 116 of the first end 104. Each of the variable-angle holes 112 extends from the upper surface 108 through the plate body 102 to the lower surface 110. In an operational configuration, the first portion 116 is configured to extend over a lateral segment of the clavicle. Each of the variable-angle holes 112 extends through the plate body 102 along a central axis and is configured to receive a bone screw passing through it at a user-selected angle relative to the central axis within a permissible angular range, such as... Figure 6 , Figure 7 and Figure 8 The triangle in the cross-section is shown. In one embodiment, the first portion 116 includes six variable-angle holes 112 extending therethrough, the variable-angle holes 112 being positioned relative to each other to maximize the number of screws that can be inserted through them to reach the side segment.

[0041] In one example, two of the variable angle holes 112 are positioned along the longitudinal axis of the plate 102. For example... Figure 6As shown, the central axis of these holes extends along a central plane C, which extends perpendicularly to the longitudinal axis of the plate 102 relative to the upper surface 108. In this embodiment, two of the variable angle holes 112 are located near the lateral edge 130 of the plate 102, on opposite sides of the longitudinal axis, and in the transverse direction relative to the farthest of the holes 112 along the longitudinal axis.

[0042] like Figure 7 As shown, the central axes of one or more of these variable angle holes 112 can converge toward the central plane C at an angle of approximately 5 degrees, such that the central axes intersect the central plane at a point distal to the lower surface 110. In one embodiment, as... Figure 7 The latter of the variable angle holes 112 shown extends along a central axis that converges toward the central plane C, while... Figure 7 The first of the variable angle holes 112 shown extends along a central axis that extends substantially parallel to the central plane C. In this embodiment, two of the variable angle holes 112 are positioned on opposite sides of a longitudinal axis, located between the two holes 112 along the central axis.

[0043] like Figure 8 As shown, one or more of these variable angle holes can be separated away from the central plane C, extending along a central axis at an angle (up to 5 degrees) relative to the central plane C, such that the central axis intersects the central plane proximal to the upper surface 108. In one embodiment, as... Figure 8 The latter of the variable angle holes shown extends along a central axis that is substantially parallel to the central plane C, while... Figure 8 The first of the variable angle holes shown extends along a central axis separated from the central plane C. Although plate 100 is specifically shown and described as having variable angle holes 112 positioned relative to each other in a particular configuration, those skilled in the art will understand that the first portion 116 may include any number of variable angle holes 112 positioned relative to each other in any of a variety of configurations, as long as bone screws can be inserted through them into different portions of the distal segment of the clavicle.

[0044] The second portion 118 of plate 102 near the second end 106 includes a plurality of variable angle holes 114, each of the variable angle holes 114 extending through it from the upper surface 108 to the lower surface 110 along a central axis substantially perpendicular to the upper surface 108. The second portion 118 is configured such that... Figure 1The identified portion of the second segment of the clavicle extends above it. In this embodiment, the central axis of the first variable-angle hole in the variable-angle hole near the second end 106 extends along the central plane C through the plate. The remaining variable-angle holes 114 are staggered relative to each other around the longitudinal axis of the plate 102. Figure 9 As shown, in this embodiment, the central axes of these variable-angle holes are at an angle of approximately 5 degrees relative to the central plane C, such that the central axes converge at a point distal to the lower surface 110. In one embodiment, the upper surface 108 may be curved about the longitudinal axis of the plate 102, such that the central axis of the variable-angle hole 114 may be substantially perpendicular to the upper surface 108. As described above, the variable-angle hole 114 may be substantially similar to the hole 112 and, as those skilled in the art will understand, is configured to receive a bone screw passing through it at a user-selected angle relative to the central axis within a predetermined angular range.

[0045] The plate 100 may also include one or more combination holes 122 extending through a central portion 134 of the plate body 102, located between a first portion 116 and a second portion 118. The combination holes 122 extend from the upper surface 108 through the plate body 102 to a distal surface and include a first portion 124 configured as a variable-angle hole and a second portion 126 configured as a clamping hole. The central portion 134 including the combination holes 122 is positioned along a portion of the plate body 102 and is configured to extend above the coracoclavicular ligament when the plate 100 is in the operating position.

[0046] The first side plate 100 may also include a plurality of suture holes 128 extending therethrough from the upper surface 108 to the lower surface 110. The suture holes 128 extend through a portion of the plate body 102, extending along a lateral edge 130 and along a longitudinal side 132. As those skilled in the art will understand, the suture holes 128 are configured to receive needles for suturing the plate to tissue and / or for receiving Kirschner wires for temporarily securing the plate 100 to bone.

[0047] Those skilled in the art will understand that, as described above, the first lateral plate 100 can be inserted via a small percutaneous incision positioned along the clavicle. The first portion 116 can then be positioned over a first (distal) segment of the bone, while the second portion 118 is positioned over a second segment of the bone when the first segment is aligned with the second segment. The plate body 102 is secured to the bone via insertion screws through combination holes 122 and variable-angle holes 112, 114 (as needed). The screws can be inserted through a small incision in the skin.

[0048] like Figures 10 to 12As shown, the second side plate 200 may be substantially similar to the first side plate 100, but its size, shape, and configuration are set to treat a clavicle larger than the first side plate 100, and / or for treating distal fractures extending more distally along a portion of the bone. Except as described below, the second side plate 200 will include the same feature portion 100 as the first side plate. Similar to the first side plate 100, the second side plate 200 includes a plate body 202 extending from a first end 204 to a second end 206.

[0049] A plurality of variable-angle holes 212 extend through a first portion 216 of the plate body 202 near the first end 204, and a plurality of variable-angle holes 214 extend through a second portion 218 of the plate body 202 near the second end 206. However, the plate body 202 may have a length range of approximately 70 mm to 100 mm. In one embodiment, the length of the plate body 202 ranges from approximately 75 mm to 95 mm, and in a more specific embodiment, the length ranges from approximately 80 mm to 90 mm. Since the length of the plate body 202 is longer than that of the plate body 102, the plate 200 may include two combined holes 222 that extend through an intermediate portion 234 of the plate body 202 between the first portion 216 and the second portion 218.

[0050] The first portion 216 includes a variable-angle hole 212, and the middle portion 234 of the plate includes a combined hole 222 extending along a curve corresponding to the distal curve of the clavicle. In one embodiment, the first portion 216 and the middle portion 234 have a radius of curvature of approximately 45 mm. The second portion 218 may extend to the medial end of the second segment of the clavicle in the operating position, such as... Figure 1 As shown, the second portion 218 extends along a curve corresponding to a portion of the inner curve of the clavicle. In one embodiment, the second portion 218 extends along a curve with a radius in the range of approximately 75 mm to 85 mm. In a specific embodiment, the second portion 218 has a radius of curvature of approximately 80 mm. In this embodiment, the second portion 218 also includes a plurality of variable angle holes 214 that are staggered around the longitudinal axis of the plate body 202. In one embodiment, the second portion 218 includes four variable angle holes 214. However, those skilled in the art will understand that the plurality of variable angle holes 214 can vary depending on the length of the second portion 218 and / or the desired configuration of the variable angle holes 214 therein.

[0051] The plate 202 may also include a dedicated area for bending in a plane to optimize the shape and configuration of the plate 200 for specific anatomical structures of the patient. In other words, the plate 202 can be bent in the same plane along which it extends. The area for bending can be configured, for example, as a width-reducing portion 236 of the plate 202 extending between the intermediate portion 234 and the second portion 218, which allows the intermediate portion 234 and the second portion 218 to bend relative to each other. The width-reducing portion 236 may include a pair of recesses 238 that extend into the longitudinal edge 232 of the plate 202.

[0052] like Figures 13 to 15 As shown, the third lateral plate 300 may be substantially similar to the second lateral plate 200, but is sized to accommodate larger patients. Similar to the second lateral plate 200, the plate body 302 is configured to extend to the medial end of the second segment of the clavicle, as... Figure 1 As shown. In one embodiment, the plate 302 may have a length ranging from approximately 80 mm to 110 mm. In another embodiment, the plate 302 may have a length ranging from approximately 85 mm to 105 mm, and in a more specific embodiment, the plate 302 may have a length ranging from approximately 90 mm to 100 mm. The first end 304 of the plate 302 may have a width between 12 mm and 23 mm, and in a specific embodiment, may have a width of approximately 17-18 mm.

[0053] The first portion 316 and the middle portion 334 of the plate 302 are configured to extend along the distal curve of the clavicle, and may have a radius of curvature between approximately 44 mm and 54 mm, and in one embodiment, may have a radius of curvature of approximately 49 mm. The second portion 318 is configured to extend along a portion of the medial curve within the second segment, and in one embodiment, may have a radius of curvature between approximately 91 mm and 101 mm, and in one embodiment, may have a radius of curvature of approximately 96 mm.

[0054] Similar to the second side panel 200, the first portion 316 includes a plurality of variable-angle holes 312. However, the first portion 316 includes more variable-angle holes 312 to accommodate a wider and longer plate body 302. The second portion 318 similarly includes variable-angle holes 314 intersecting the longitudinal axis of the plate body 302. However, the second portion 318 also includes one or more additional combination holes 322 extending through the distal end of the second portion 318, such that a curved region 336 extending between the intermediate portion 334 and the second portion 318 extends between two adjacent combination holes 322.

[0055] Those skilled in the art will understand that one of the three side plates 100-300 as described above can be selected for treating a patient based on the patient's body size (e.g., patient = clavicle size) and / or the location of the fracture along the bone. While exemplary embodiments are specifically described and illustrated with three side plates of different sizes and configurations, the system disclosed herein may include more than three side plates for adapting to different sizes of clavicles.

[0056] The clavicle system disclosed herein also includes axial plates 400-700, which are used to treat fractures along the second, third, and / or fourth segments of the clavicle, such as... Figure 1 As shown. Specifically, each of the three plates 400-600 is designed to treat fractures extending from the medial portion of the second segment to the medial end of the third segment. Each of the three plates 400-600 is different in size and shape to treat axial fractures extending through different sizes of the clavicle. Plate 700 may be specifically configured to treat extended fractures and is configured to extend along the fourth segment of the clavicle. Elongation fractures along small bones may also be treated using, for example, a medium-sized plate (e.g., plate 500), while elongation fractures along medium-sized bones may also be treated using a large plate (e.g., plate 600).

[0057] like Figures 16 to 18 As shown, the first axial plate 400 includes a plate body 402 extending from a first end 404 to a second end 406, and is defined via a proximal surface 408 facing away from the bone in the operating position to a distal surface 410 facing the bone in the operating position. Similar to the second end of the aforementioned side plate, the first end 404 and the second end 406 of the plate body 402 include an inclined surface 420 connecting the proximal surface 408 to the distal surface 410, which reduces the profile of the plate 400 at the second end 406 to facilitate plate insertion through a percutaneous incision.

[0058] As described above, in the operating position, the plate 402 extends along a portion of the second segment of the clavicle to the medial end of the third segment. Specifically, the plate 402 includes a first portion 416 and a second portion 418, the first portion being sized, shaped, and configured to extend along a portion of the distal curve of the clavicle, and the second portion being sized, shaped, and configured to extend over a portion of the medial curve of the clavicle when the plate 400 is in the operating position. As will be described in more detail below, each of the first portion 416 and the second portion 418 includes a first set of variable angle holes 412 and a second set of variable angle holes 414, together with a combination hole 422 extending from the proximal surface 408 through it to the distal surface 410.

[0059] In one embodiment, plate 402 may have a length ranging from approximately 80 mm to 115 mm. In another embodiment, the length of plate 402 may range from approximately 85 mm to 110 mm, and in a more specific embodiment, the length of plate 402 may range from 90 mm to 105 mm. In one embodiment, a first portion 416 extends along a curve having a radius of curvature between approximately 40 mm and 50 mm, and in a specific embodiment, the radius of curvature may be approximately 45 mm. A second portion 418 may extend along a curve having a radius of curvature between approximately 70 mm and 80 mm, and in a specific embodiment, may have a radius of curvature of 74 mm.

[0060] In one embodiment, the first portion 416 includes a first set of variable angle holes 412 extending along the first portion from the first end 404. The first variable angle hole 412 near the first end 404 extends through the plate 402 along its longitudinal axis. Subsequent variable angle holes 412 may be staggered relative to each other about the longitudinal axis. In one embodiment, the first portion 416 includes four variable angle holes 412. Similar to the first portion 416, the second portion 418 may include a plurality of variable angle holes 414 extending along the second portion from the second end 406. The first variable angle hole 414 near the second end 406 extends through the plate 402 along the longitudinal axis. Subsequent variable angle holes 414 may be staggered relative to each other about the longitudinal axis. The first set of variable angle holes 412 and the second set of variable angle holes 414 may be substantially similar to those described above. Figures 3 to 9 The variable angle aperture 114 is shown. Specifically, each of the apertures 412 and 414 extends along a central axis that is angled relative to the central plane, such that the central axis converges with the central plane on the distal side of the distal surface 410.

[0061] The plate 400 also includes a plurality of combination holes 422 extending through the plate body 402 between a first set of variable angle holes 412 and a second set of variable angle holes 414. In one embodiment, the plate 400 may include four combination holes 422. The combination holes 422 extend substantially along a longitudinal axis through the plate body 402. In one embodiment, the configuration of the holes along the first portion 416 and the second portion 418 is substantially mirror-image of each other. Specifically, the second portion 418 may similarly have four variable angle holes. Furthermore, the combination holes 422 extending along the first portion 416 may have variable angle hole portions 424 extending inward toward the clamping hole portion 426, while the combination holes 422 extending along the second portion 418 may have variable angle portions 424 extending laterally toward the clamping hole portion 426. Those skilled in the art will understand that the first screw and the second screw can therefore be initially inserted through the combination holes 422 along the first portion 416 and the combination holes 422 along the second portion 418 to clamp a fracture of bone along which the plate 400 is implanted.

[0062] like Figures 19 to 21 The second axial plate 500 shown may be substantially similar to the first axial plate 400. However, the size, shape, and configuration of the second axial plate 500 are configured to treat a clavicle having a larger size than the first axial plate 400. The second axial plate 500 similarly includes a plate body 502 comprising a first portion 516 configured to extend along a portion of the distal curve of the clavicle and a second portion 518 configured to extend along a portion of the medial curve of the clavicle. In this embodiment, the plate body 502 has a length range of approximately 95 mm to 125 mm. In another embodiment, the length range of the plate body 502 is approximately 100 mm to 120 mm, and in a more specific embodiment, the length of the plate body 502 extends approximately 105 mm to 115 mm.

[0063] The first portion 516 extends along a curve, which in one embodiment has a radius of curvature in the range of approximately 45 mm to 55 mm, and in a specific embodiment has a radius of curvature of approximately 50 mm. The second portion 518 extends along a curve, which in one embodiment has a radius of curvature of approximately 82 mm to 92 mm, and in a specific embodiment has a radius of curvature of approximately 87 mm. A first set of variable angle holes 512 and a second set of variable angle holes 514 pass through and extend along the first portion 516 and the second portion 516, which are substantially similar to the plate 400, together with the combination hole 522.

[0064] like Figures 22 to 24The third axial plate 600 shown may be substantially similar to the first axial plate 400 and the second axial plate 500, but may be particularly suitable for patients with larger clavicle sizes. Similarly, the third axial plate 600 includes a plate body 602 comprising a first portion 616 configured to extend along a portion of the distal curve of the clavicle, and a second portion 618 configured to extend along a portion of the medial curve of the clavicle. In this embodiment, the plate body 602 may have a length range of approximately 110 mm to 140 mm. In a specific embodiment, the length of the plate body 602 may be in the range of approximately 125 mm to 135 mm, and in a more specific embodiment, in the range of approximately 120 mm to 130 mm.

[0065] The first portion 616 extends along a curve, which in one embodiment has a radius of curvature in the range of approximately 54 mm to 64 mm, and in another more specific embodiment has a radius of curvature of approximately 59 mm. The second portion 618 extends along a curve, which in one embodiment has a radius of curvature of approximately 93 mm to 103 mm, and in another more specific embodiment has a radius of curvature of approximately 98 mm. The third shaft plate 600 similarly includes a first set of variable angle holes 612 and a second set of variable angle holes 614, which, together with a combination hole 622, extend through the first portion 616 and the second portion 618. However, the third shaft plate 600 includes additional holes 612, 614, 622 to cover a longer length of the plate body 602.

[0066] like Figures 25 to 26 The fourth axial plate 700 shown can be substantially similar to axial plates 400-600. Specifically, the fourth axial plate 700 includes a plate body 702, which is similar in shape to plate body 602 and has substantially similar radii of curvature along the first portion 716 and the second portion 718. However, plate body 702 has a longer length and is specifically designed to accommodate elongated axial fractures. In one embodiment, the fourth axial plate 700 is configured to extend along a portion of the second segment of the clavicle to the medial end of the fourth segment of the clavicle, as shown in the figure. Figure 1 As shown. In this embodiment, the plate 702 may have a length ranging from approximately 130 mm to 160 mm. In another embodiment, the length of the plate 702 may be in the range of approximately 135 mm to 155 mm, and in a more specific embodiment, in the range of approximately 140 mm to 150 mm.

[0067] As mentioned above, the standard clavicle system does not include a designated medial plate. Currently, an appropriate outer plate (e.g., the distal humeral plate and distal radius plate) is frequently used to treat medial fractures, which in some cases does not provide an optimal fit to the clavicle. Figures 27 to 29As shown, the size, shape, and configuration of the medial plate 800 are specifically designed for treating medial fractures of the clavicle. The medial plate 800 includes a plate body 802 extending from a first end 804 to a second end 806, and is defined by a proximal surface 808 facing away from the clavicle in the operating position to a distal surface 810 facing the clavicle in the operating position.

[0068] The size and shape of the plate 802 are such that, in the operating position, the second end 806 extends on the anterior surface of the medial end of the clavicle, and the length of the plate 802 extends through the fifth segment of the clavicle and along a portion of the fourth segment of the clavicle towards the superior surface. Therefore, as... Figure 29 As shown, the first end 804 of the plate 802 rotates about the longitudinal axis of the plate 802 relative to the second end 806. In this embodiment, the first end 804 includes an inclined surface 820 connecting the proximal surface 808 and the distal surface 810 to form a low profile, thereby facilitating the insertion of the plate 800 through a percutaneous incision.

[0069] In this embodiment, the plate body 802 includes a longitudinally extending assembly 840 and an extension portion 842 extending from a second end 806 such that, when the plate 800 is in the operating position, the extension portion 842 extends toward the superior surface of the clavicle. The extension portion 842 extends laterally from the longitudinally extending assembly 840, away from the longitudinal axis of the longitudinally extending assembly 840. Along the distal surface 810 of the plate body 802, the plate 800 also includes a groove 844 extending between the extension portion 842 and the longitudinal assembly 840, such that the extension portion 842 can be bent relative to the longitudinal assembly 840 along the groove 844, thereby better adapting the plate 800 to the specific anatomy of the patient.

[0070] A second end 806 of a plate 802, including an extension 842, defines a second portion 818 of the plate 802, along which a first set of variable-angle holes 812 extends. In one embodiment, the first pair of variable-angle holes 812 extends from a proximal surface 808 to a distal surface 810 near the medial edge 807 of the longitudinal assembly 840. Another variable-angle hole 812 also extends through the extension 842, such that the variable-angle hole 812 extending adjacent to the medial edge 807 and the extension are substantially aligned. In this embodiment, a second pair of variable-angle holes 812 is located adjacent to the first pair of variable-angle holes 812 in its lateral direction. These variable-angle holes 812 are configured to allow insertion of bone screws into the medial portion of the clavicle.

[0071] A second set of variable angle holes 814 extends along a first portion 816 of a plate 802 including a first end 804. A first variable angle hole 814 extends through the plate 802 near the first end 804. The central axis of the first variable angle hole 814 passes through the longitudinal axis of the plate 802 and extends along a central plane that passes through a longitudinal axis substantially perpendicular to the proximal surface 808. Similar to variable angle holes 114-714, the remaining variable angle holes 814 are staggered relative to each other along the first portion 816 of the plate 802, about the longitudinal axis of the plate 802. A combination hole 822 extends along a portion of a longitudinal assembly 840 of the plate 802, which extends between the first portion 816 and the second portion 818.

[0072] Similar to side plates 200-300, the medial side plate 800 includes a bending region 836 to facilitate bending of the plate body 802, thereby better adapting to specific patient anatomy. In this embodiment, the bending region 836 is positioned between adjacent combination holes 822 and is formed as a width-reduced portion, for example, defined by a pair of recesses 838 extending along the longitudinal assembly 840 into the longitudinal side 832. Although a single medial side plate 800 has been described and shown, those skilled in the art will understand that the systems disclosed herein may include more than one medial side plate, each with different dimensions, shapes, and / or configurations suitable for treating patients with different bone sizes.

[0073] According to an exemplary method of the system disclosed herein, a user identifies the location of a clavicle fracture relative to one of five segments, as described above. Figure 1 As shown. Based on the identified segment, the user determines which type of plate (e.g., lateral plate, axial plate, and / or medial plate) to use to treat the fracture. Once the user has determined the type of plate to be used, the size of the identified plate type (e.g., lateral plate 100-300) can be selected based on the patient's body size. To help identify the size of the plate to be used, the user can use a template whose size and shape are set according to the size of each available plate to determine whether the size of the selected plate fits the patient well.

[0074] Those skilled in the art will understand that although exemplary embodiments show and describe plates of a specific size, the systems disclosed herein may include additional plates designed to include sizes corresponding to the bone dimensions of patients with different body types. For example, although exemplary embodiments describe plates based on a clavicle database broadly categorized into three classes, those skilled in the art will understand that the system may include plates based on bone dimensions categorized into more than three classes.

[0075] Those skilled in the art will understand that modifications and variations can be made to the structure and method of the embodiments without departing from the spirit or scope of the embodiments of the present invention. Therefore, the embodiments of the present invention are intended to cover various modifications and variations of these embodiments, provided that they fall within the scope of the appended claims or their equivalents.
