Description

Technical Field

[0001] (Cross - reference to Related Applications) This application claims priority to U.S. Patent Application No. 18 / 351983, filed with the United States Patent and Trademark Office on July 13, 2023, the content of which is hereby incorporated by reference in its entirety.

[0002] (Field of the Invention) Various exemplary embodiments disclosed herein relate to an outer proximal tibial plate having an extension arm.

Background Art

[0003] Tibial plates have been developed to address fractures of the tibia, including fractures of the proximal tibia. Specifically, treating fractures at the posterolateral corner of the proximal tibia is challenging because surrounding soft tissues, such as arteries and nerves, make it difficult to approach such fractures. The outer proximal tibial plate can include a head and a body. The body can extend along the tibia and includes screw holes to enable attachment of the tibial plate to the tibia. The head can include a row of screw holes at the end of the tibial plate. When screws are placed in these holes, the screws can be used to capture, reduce, and fix fractured bone fragments.

Embodiments for Carrying Out the Invention

[0028] Various aspects of this disclosure will be fully described below with reference to the accompanying drawings. However, since this disclosure can be embodied in many different forms, it should not be construed as being limited to any particular structure or function presented throughout this disclosure. Rather, these aspects are provided to make this disclosure thorough and complete and to fully convey the scope of this disclosure to those skilled in the art.

For example, an apparatus may be implemented or a method may be carried out using any number of aspects described herein. Furthermore, the scope of this disclosure is intended to cover any other structure, function, or such apparatus or method carried out using other structures, functions, or structures and functions in addition to the various aspects of the disclosure described herein. It should be understood that any aspect of the disclosure disclosed herein may be embodied by one or more elements of the claims.

[0029] Several embodiments of tibial plate systems are presented below with reference to various devices and techniques. Treatment of fractures at the posterolateral angle of the proximal tibia is challenging because surrounding soft tissues such as arteries and nerves make it difficult to access such fractures. However, the incidence of these fractures is continuously increasing, for example, due to the rising number of scooter accidents, in which the distal femoral component of a flexed knee strikes the posterior portion of the proximal tibia. Experienced surgeons may use other plates, such as a general T-plate or oblique T-plate, which can be applied as a direct posterior buttress on the fracture fragment when the patient is treated in the prone position. However, these fractures often occur simultaneously with other proximal tibial fractures, including bicondylar fractures and compound fractures, and it is preferable to treat all fractures in the supine position as they are easily accessible.

[0030] The novel tibial plate disclosed herein is a lateral proximal tibial plate having a posterolateral extension arm. The plate is intended to be positioned near the articular margin so that screws can be inserted just below the articular surface to obtain the necessary support. The extension arm is an extension from the most proximal row of screw holes to the posterior horn, for example, including three to four additional screw holes. The shape of the extension arm allows for the adaptability of the extension arm to take into account the variation in tibial morphology between subjects, depending on its shape, material, and / or thickness. The tibial plate disclosed herein is intended to be a flexible and adaptable buttress plate that provides a valuable addition / improvement in the treatment of complex fractures of the proximal tibia in patients.

[0031] Figures 1A to 1D show perspective views, magnified perspective views, top views, and lateral views of a tibial plate on the tibia. Figures 1A to 1D show the tibia 2 and fibula 4, with the tibial plate 6 attached to the tibia 2. The tibial plate 6 includes an extension arm 18 extending from a head 14. The extension arm 18 wraps around the posterior horn to engage with the posterior part of the tibia. The extension arm 18 may extend along the articular margin near the articular surface of the tibia 2.

[0032] Figures 2A to 2F show perspective views, top views, first lateral views, second lateral views, bottom views, and end views of the tibial plate 6. The tibial plate 6 has a body 16 and a head 14. As shown in the figures, the tibial plate 6 is generally L-shaped, but may have a head 14 that extends beyond both sides of the body 16, giving it a T-shape. An extension arm 18 extends from the head 14 and curves back toward the head 14 of the tibial plate 6.

[0033] The extension arm 18 may have one or more plate screw holes 10. The plate screw holes 10 can be of various types, namely, threadless, threaded, variable angle, set screw, etc. The plate screw holes 10 of the extension arm 18 are shown as threaded in Figures 2A to 2F.

[0034] The head 14 of the tibial plate 6 extends along the articular edge of the tibia 2 near the articular surface of the tibia 2. Although the head 14 is shown having four plate screw holes 10, the head 14 may have fewer or more plate screw holes 10. As described above, the plate screw holes 10 can be of various types, i.e., threadless, threaded, variable angle, set screw, etc.

[0035] The head 14 may also include a plurality of plate guide holes 12. The plate guide holes 12 may be used to guide the placement of the K-wire within the tibial plate 2. This may be done, for example, during the initial placement of the tibial plate 6. Furthermore, the plate guide holes 12 may be used as suture holes.

[0036] The main body 16 generally extends along the length of the tibia 2, away from the head 14. The main body 16 can include various different types of holes. Plate guide holes 12 may be included near the tip of the main body 16, away from the head 14. These may be used to help secure the tibial plate 6 during initial placement. The main body 16 may include any number (including zero) of plate screw holes 10. Furthermore, the main body 16 may include combination screw holes 24. The combination screw holes 24 accept both standard screws and set screws. The number and location of the combination screw holes 24 may vary depending on the specific clinical needs to be addressed. The combination screw holes 24 provide the flexibility to use either standard screws or threaded screws to secure the tibial plate 6 to the tibia 2. The main body 16 may include elongated holes 22, which are elongated holes along the length of the main body 16 and therefore along the length of the tibia 2. These elongated holes 22 allow for some flexibility and adjustment when securing the tibial plate 6 to the tibia 2. The plate screw 8 can be positioned in the elongated hole 22 but not fully tightened. This can help to initially secure the tibial plate 6 to the tibia 2. Because the plate screw 8 is not fully tightened, the tibial plate 6 can move along the elongated hole 22, allowing for adjustment of its position on the tibia 2. When the tibial plate 6 is in its final position, the plate screw 8 in the elongated hole 22 can be tightened to help securely fix the tibial plate 6 in place.

[0037] The main body 16 also includes a transverse hole 20. The transverse hole 20 is an elongated hole extending across the width of the main body 16, and is therefore elongated laterally. This transverse hole 20 may be used during surgery to generate the necessary posterior-to-anterior compression of the posterolateral fragment against the tibia after the cortical bone screws have already been pre-positioned within the transverse hole 20 during preliminary plate positioning. Thus, the tibial plate 6 can slide anteriorly under the cortical bone screws. After the plate screws 8 are positioned in the transverse hole 20, a reducing force can be applied to the tibia to reduce the fracture. Such reduction can be performed using various known techniques. One method of reducing the fracture is by using a clamping tool 100, which will be further described below. Once the fracture site is reduced and compressed, additional screws may be placed in other plate screw holes 10 of the head 14 to fix the reduced fracture site. Once the fracture site is reduced, the plate screw holes 10 in the transverse hole 20 can be tightened.

[0038] Figures 3A to 3D show perspective views, magnified perspective views, end views, and side views of a clamp tool applied to a tibial plate on the tibia. To apply a reducing force to the fracture site of the tibia, the clamp tool 100 can be applied to engage one of the plate screw holes 10 of the extension arm 18 with the tibia 2 on the opposite side of the extension arm 18. Furthermore, the clamp tool 100 can be bent to fit the articular edge of the tibia 2.

[0039] Figures 4A and 4B show perspective and side views of the clamp tool 100. The clamp tool 100 includes two arms 102 connected by a pivot fastener 116 that allows the arms 102 to pivot. One arm 102 includes a slotted projection 108 having a slot for receiving a screw 104. One end of the screw 104 is connected to the other arm 102. A nut 106 is fitted onto the screw 104 and tightened to engage with the slotted projection 108, thereby maintaining the clamp tool 100 in a clamped state on the tibia 2. The extension head 104, extension body 106, and interface surface 108 function as a locking mechanism for locking the clamp tool in a specific position. The screw 104 can swing away from the slotted projection 108, releasing the clamp tool 100. The arms 102 may include a handle 114 that allows the user to hold and apply the clamp tool 100.

[0040] The ends of the arm 102 curve inward toward each other and have sharp tips 112 for engaging with the tibia 2. Furthermore, although the ends are shown to be symmetrical, they may be asymmetrical and may have other shapes including multiple bends. In addition, a ball interface 110 is located at the end of the arm 102. The ball interface 110 is configured to engage with the plate screw hole 10 of the extension arm 18 of the tibial plate 6. The ball shape of the ball interface 110 allows for easy positioning of the ball interface 110 within the plate screw hole 10, even when the plate screw hole 10 is not visible. The tip 112 extends outward from the ball interface 110 to grasp the tibia 2. During use, one ball interface 110 on the first arm 102 engages with the plate screw hole 10 of the extension arm 18, and the tip 112 on the second arm 102 engages with the tibia 2 on the opposite side of the extension arm 18. The surgeon can apply a reducing force to the fracture site in order to reduce the fracture. Furthermore, this force can bend the extension arm 18 to fit the articular edge of the tibia 2.

[0041] Next, the method of using the tibial plate 6 and clamp tool 100 will be described. First, the surgeon can make an incision in the tibia 2 to apply the tibial plate 6. If a simple fracture of the joint or an extra-articular fracture is present, a transverse "S" shaped incision may be used. If a complex intra-articular fracture is present, an anterolateral approach is used to make an anterolateral incision. Next, an arthrotomy is performed to expose the joint for reduction. If necessary, the incision may be extended to fully expose the joint for reduction and anatomical fixation. Regardless of the surgical incision used, care should be taken to minimize the dissection of soft tissue.

[0042] The next step involves reducing the articular surface of tibia 2. Note that applying an external fixator or stretcher before reduction can facilitate reduction and visualization of the joint. Reduce the fractured fragments of the joint and confirm the reduction using image enhancement and direct visualization if possible. After reduction, the fragments can be temporarily fixed using independent K-wires. The independent K-wires are positioned coplanar with the lateral plateau cortex, thereby preventing collision with plate insertion. Plate guide holes 12 are also provided in the tibial plate 6 to maintain the temporary reduction and help establish the temporary position of the plate.

[0043] Next, the surgeon determines the type of plate to use to treat the fracture. It should be noted that fractured bone can spread, potentially leading to the selection of the wrong plate type. In this case, X-ray images of the other limb may be useful for comparison and planning.

[0044] Next, the tibial plate 6 and its extension arm 18 are contoured as needed to fit the specific fractured tibia 2. The tibial plate 6 with the extension arm 18 is anatomically pre-contoured, although the extension arm 18 may require contouring to achieve some preloading on the posterolateral bone fragment.

[0045] The surgeon then inserts a K-wire into the plate guide hole 12 of the plate head to pre-fix the tibial plate 6 to the tibia 2. Before proceeding, the surgeon confirms the placement of the tibial plate 6 through clinical examination and fluoroscopy, and readjusts the position of the tibial plate 6 if necessary.

[0046] Next, the tibial plate 6 is pre-secured to the anterior side of the transverse hole 20 in the neck of the tibial plate 6 using screws such as cortical bone screws. Then, a drill bit is inserted into a universal drill guide. In this example, the drill bit may be 2.5 mm, but other sizes may be used as well. The drill bit is then advanced until the desired depth is reached. Next, the drill bit and drill guide are removed. At this point, the surgeon measures the length of the plate screw 8 using a depth gauge, either by reading or using a calibrated drill bit. The surgeon then inserts a plate screw 8 of the appropriate length into the drilled hole. This may be, for example, a 3.5 mm cortical bone screw, but other lengths and types of screws may be used as well.

[0047] Before final tightening, the surgeon uses a clamping tool 100 to apply compression between the plate screw hole 10 of the extension arm 18 (for example, the plate screw hole 10 at the end of the extension arm 18) and the anterior surface of the tibia 2. The inserted plate screw 8 is then tightened to maintain the compression.

[0048] After compression by the clamp tool 100 is applied to the posterolateral bone fragment, the compression must be maintained by a screw-plate fixation system. One way to achieve this is to insert a cortical bone screw into the first hole of the extension arm in a trajectory from posterolateral to anteromedial. This pushes the extension arm toward the fragment. Since this cortical bone screw can be angled distally, its trajectory does not collide with a rafting screw from the lateral side located beneath the articular surface.

[0049] For final tightening, the screwdriver shaft may be assembled with a handle for manually tightening the screws. Before proceeding, use clinical examination and fluoroscopy to confirm that the plate is properly oriented on the tibial plateau, that the trajectory of the plate screws 8 within the proximal plate screw holes 10 is parallel to the joint in transverse plane (this may vary slightly based on individual anatomical structures and any bending that occurs in the tibial plate 6 during tightening of the plate screws 8), and that the alignment of the plate with respect to the tibial diaphysis is correct when viewed from both the anterior-posterior (AP) and lateral directions.

[0050] The K-wire inserted for preliminary fixation may be removed. It should be noted that proper positioning of the tibial plate 6 is crucial for the successful treatment of a tibial fracture. If the tibial plate 6 is positioned too distally, it will not provide sufficient rafting support to the joint surface, and if the plate is positioned too proximal, the proximal threads may damage the joint area. To avoid screw collision between the plate threads 8 in the extension arm 18 and the plate threads 8 in the head (i.e., in the plate thread holes 10 at the end of the head 14 of the tibial plate 6), a long drill guide may be inserted to check the trajectory.

[0051] Finally, the plate screws 8 are inserted into the plate screw holes 10 of the proximal rafting row (i.e., the plate screw holes 10 at the end of the head 14 of the tibial plate 6). These screws may be 3.5 mm variable angle set screws, but other screw sizes and types may also be used. Next, the plate screw holes 10 are positioned on the shaft of the tibial plate 6. These screws may be 3.5 mm cortical bone screws, but other sizes and types of screws may also be used.

[0052] Optionally, an incision can be made to create an additional posterolateral approach window, and a screw can be placed in a hole at the end of the extension arm.

[0053] The Tibial Plate 6 is intended to be a flexible and adaptable buttress plate that provides a valuable addition / improvement in the treatment of complex fractures of the proximal tibia in patients.
