Abstract: A tibial support structure includes a platform portion and a medullary portion that are monolithically formed as a single piece. The medullary and platform portions of the augment component are adapted to accommodate and mechanically attach to a tibial baseplate, and are individually shaped and sized to replace damaged bone stock both within the tibia, as well at the tibial proximal surface. The monolithic formation of the tibial support structure provides a strong and stable foundation for a tibial baseplate and facilitates restoration of the anatomic joint line, even where substantial resections of the proximal tibia have been made. The tibial support structure may be made of a bone-ingrowth material which facilitates preservation and rebuilding of the proximal tibia after implantation, while also preserving the restored joint line by allowing revision surgeries to be performed without removal of the tibial support structure.

Abstract: A bone augment adaptor is configured to be inseparably coupled to a bone augment. A first end of the adaptor is configured to be connected to an epiphyseal replacement portion of a modular joint replacement prosthesis. A second end of the adaptor may be configured to be connected to a diaphyseal anchoring portion of the prosthesis.

Abstract: Porous spacers (100) are provided for foot and ankle fusion. The porous spacers disclosed herein may be implanted between separate bones of a joint or between two segments of a single bone following an osteotomy procedure. Such spacers may be used in conjunction with an ankle resection system which includes a resection frame (150) and a resection guide (170). The resection frame can be anchored to the distal tibia and/or the talus and provides an opening (155) through which a bone cutting element can pass for cutting underlying bone. The resection guide can include one or more cutting slots (169, 171, 172) and the resection guide can be coupled to the resection frame with the one or more cutting slots positioned over the opening in the resection frame so that the bone cutting element can pass through the one or more cutting slots and through the opening in the resection frame for cutting the distal tibia and/or the talus.

Abstract: An apparatus for removal of a femoral implant may include a handle portion and a cutting blade opposite the handle portion. The cutting blade may include a cutting edge, wherein the cutting edge includes a non-linear shape to substantially match at least a portion of a profile of the femoral implant to be removed.

Abstract: An orthopedic device holder and related system and method are disclosed. The orthopedic device holder can include a body member, a cannulated plunger, and a resilient member. The body member can include a longitudinal main body and an extension portion. The cannulated plunger can be slidably mounted inside the body member and movable between a first position and a second position. The plunger can be configured such that in the second position, a plunger distal end extends past a main body distal end, and in the first position, the plunger distal end assumes a more proximal position. The resilient member can be positioned adjacent a plunger proximal end and can be configured to urge the plunger towards the second position. The extension portion of the body member can project distally from the main body distal end and can include a locking member, which can be configured to fit into a mating recess of an orthopedic device.

Abstract: An orthopedic system according to one embodiment of the disclosure comprises a first trial member capable of forming a broach cavity in a first bone of a patient. A second trial member is removeably coupleable to the first trial member in a fixed alignment with respect to the trial member. An alignment member is removeably coupleable in a fixed alignment with respect to the first trial member. The alignment member comprises indicia configured to provide for alignment of the alignment member with respect to at least one of the first bone and a second bone of the patient. The alignment of the second trial member with respect to the first trial member when coupled to the first trial member corresponds to the alignment of the alignment member with respect to the first trial member when coupled with the first trial member.

Abstract: An implant can comprise a porous region including a plurality of interconnecting interstitial cells configured to receive bone or biological tissue ingrowth. The porous region can be formed of a first portion, including a first plurality of the interconnecting interstitial cells and having a first density, and a second portion, including a second plurality of the interconnecting interstitial cells and having a second density different than the first density. The plurality of interconnecting interstitial cells can form a framework onto which a material can be disposed in different amounts to provide the first and second densities of the first and second portions, respectively. The second density can be selected and configured to provide greater bone or biological tissue ingrowth than the first density. The first and second density can be selected and configured to substantially match an anisotropic property of a body component the implant is intended to replace or augment.

Abstract: A trochanter attachment device can include a plate for attachment to an inner portion of a greater trochanter of a femur, a collar for attaching the plate to a hip implant, and a fastener for securing the collar to a hip implant. The trochanter attachment device can include a groove or other feature for receiving a reinforcing material, such as a wire or a cable, such as to reinforce an attachment of the device to the greater trochanter and/or the hip implant. The trochanter attachment device can include an insert attachable to the plate and configured to attach the plate to the greater trochanter. All or a portion of the plate and/or the insert can include a porous material, such as to promote bone ingrowth of the greater trochanter.

Abstract: The present disclosure relates, in some aspects, to orthopaedic implants for securing soft tissue to bone and methods for using the same. One particular implant comprises a first exposed porous surface region, having pores for promoting bone ingrowth, and a second exposed porous surface, having pores for promoting soft tissue ingrowth. At least some of the pores of the first exposed porous surface region may be seeded with osteocytic factors and at least some of the pores of the second exposed porous surface region may be seeded with fibrocytic factors. Such orthopaedic implants can advantageously facilitate regeneration of the soft tissue to bone interface.

Abstract: A conical burr template is indexed to the intramedullary canal of a tibia, such that a burr may trace the periphery of the template to define a correspondingly shaped cavity in the bone which is properly sized, shaped, and positioned to receive a cone-shaped tibial augment component. Advantageously, use of the burr template promotes expedient surgery while maintaining optimal fit characteristics and proper spatial placement of the tibial cone augment.
