The stem extends from the base perpendicular to the bone support surface and is configured for insertion in a medullary canal (23) of an amputated bone (20), the bone support surface (4) being configured for abutment against a severed end (22) of said amputated bone. A diameter (d1) of the base is configured to be larger than an average diameter of a shaft (21) of said severed bone, the soft tissue load bearing surface (5) comprising a generally planar or slightly curved central portion (10) and a convexly curved radially outward portion (11) with a curvature greater than the central portion, the central portion (10) being oriented at an angle of between 4° to 8° to the bone support surface.

A method and system provide and use a patellar implant. The patellar implant includes a superior portion, an inferior portion opposite to the superior portion, and an anterior portion. The superior portion being configured to reside below a patellar tendon and to elevate and/or tilt the patellar tendon. The inferior portion is configured to be seated in proximity to a tibia. The anterior portion is between the superior portion and the inferior portion. The anterior portion is placed in proximity to a patella. In one aspect, the method includes inserting the implant beneath the patellar tendon and between the patella and a position at which the patellar tendon is affixed to the tibia. In this aspect, the method also includes affixing the implant.

An intercalary prosthesis for spanning portions of a long bone includes a first intramedullary component that has a first stem and a first connector disposed at one end of the first stem. The first stem is configured to be received within an intramedullary canal of a long bone. A second intramedullary component has a second stem and a second connector disposed at one end of the second stem. The second stem is configured to be received within an intramedullary canal of the long bone. The prosthesis also includes a connector component. The connector component has a body that includes opposing ends each with a connector configured to respectively connect to the connectors of the first and second intramedullary components. The body also has an outer shell and an inner lattice structure disposed within and connected to the outer shell.

Implants and related methods for achieving dynamic fixation are disclosed. The implant comprises a head portion at a proximal end of the implant comprising external threads and a first axial through hole, and an anchor portion extending from the head portion at a distal end of the implant comprising external threads and a second axial through hole in communication with the first axial through hole. The implant further comprises a flexible constraint member extending within the first and second axial through holes comprising a first end portion coupled to the head portion and a second end portion coupled to the anchor portion. At least one of the head portion and the anchor portions forms a breakaway portion with aligned internal and external circumferential grooves configured to concentrate stress thereat such that the breakaway portion fractures via forces acting on the implant to separate the head and anchor portions.

An orthopaedic prosthetic component comprises a fixation peg including a porous three-dimensional structure configured to permit bone in-growth. The porous three-dimensional structure has an outer surface boundary. The fixation peg includes a plate attached to the porous three-dimensional structure at the outer surface boundary. The plate includes a tapered body having an outer wall that faces away from the porous three-dimensional structure and is devoid of any openings.

A method for treating arthritis of a joint includes identifying a bone lesion in a bone adjacent to the joint; and implanting in the bone a reinforcing member in or adjacent to the bone lesion. A kit for conducting the method includes: (a) at least one reinforcing member having a proximal face adapted to face the joint, a distal face adapted to face away from the joint, and a wedge-shaped edge adapted to pierce bone, wherein the at least one reinforcing member is planar and sterile; and (b) a container adapted to maintain the at least one reinforcing member sterile. Another kit includes: (a) a sterile fluid; (b) a syringe for injecting the fluid into a bone; (c) a curing agent adapted to cure the fluid to polymerize and/or cross-link; and (d) a container adapted to maintain the sterility of contents of the container.

Orthopedic implants and related surgical methods for using same. The implants have suture bore geometries that facilitate performance of the surgical methods, thereby providing for improved optimal biomechanical force application in various anatomies. The implants include suture bores that have an angled/diagonal, or skewed, orientation within the anatomical planes (lateral/sagittal and frontal/coronal). The suture bores have the skewed orientation so that the adjacent soft tissues (i.e., tendons or ligaments) can be advanced via the suture therethrough in superior-inferior and inferior-superior directions. Openings, or holes, at the ends of the suture bores are configured to approximate the adjacent associated soft tissue to the implant.

A method for treating a bone includes cutting away a portion of the bone, including cutting non-planar features into the bone for engagement by implant components. The method further includes fitting the multiple implant components to the bone, with at least some of the multiple implant components engaging the non-planar features cut into the bone. The implant components interlock such that later added implant components secure earlier added implant components in place on the bone.

Implants, devices, systems, and methods for achieving ligament fixation are disclosed. An implant is disclosed that includes a head member, a breakaway portion, and an anchor member. The anchor member may be coupled to the head member by the breakaway portion. The implant may be designed to fail in fatigue at the breakaway portion. The breakaway portion may thereby extend between a first end of the anchor member and a second end of the head member. The breakaway portion may comprise a circumferential groove. The groove may be configured to concentrate stress forces in situ such that a fatigue failure/fracture occurs at the groove. Insertion instruments for inserting an implant for ligament fixation are also disclosed. Methods of using an implant for achieving ligament fixation are also disclosed.

A bone void forming assembly includes a support member having a head portion and an elongate portion extending therefrom. A guide member is connected to the support member and has a guide body including a channel extending therethrough. The channel defines an axis offset and obliquely angled relative to an axis of the elongate portion. The assembly also includes reamer having a cutting head and a stop member. A bushing is slidably connected to the reamer between the stop member and cutting head and is slidably connectable to the guide body via the channel.
