  • Patent number: 12274455
    Abstract: A distal femoral joint replacement system includes a femoral component having condylar articular surfaces, a stem extending from the femoral component, and a void filler for filling a bone void within a femur. The void filler includes a body and a plurality of legs extending from the body. The body has a sidewall defining an opening for receipt of the stem which extends along a length of the body and extends through the sidewall so as to form a side-slot in the sidewall that extends along an entire length of the sidewall. The plurality of legs each have a first end connected to the body and a second end remote from the body. The legs each have an outer surface that tapers between the first and second ends and is configured to register with a corresponding inner surface of a bone void when implanted in an end of the femur.

  • Publication number: 20240315849
    Abstract: A hinge knee system includes a tibial assembly having a baseplate component and an axle component. The baseplate component has an opening that extends therein from a proximal end toward a distal end thereof. The axle component has a shaft portion receivable within the opening of the baseplate component and an axle connected to the shaft portion that extends in a direction transverse to a longitudinal axis of the shaft portion. The system also includes a femoral assembly that includes a distal femoral component. The distal femoral component includes condylar portions and an intercondylar portion disposed between the condylar portions. The intercondylar portion includes a bearing surface that defines a recess configured to rotatably receive the axle for articulation therewith.

  • Publication number: 20240299178
    Abstract: A modular implant system includes a baseplate, a bearing insert and a latch. The baseplate is adapted to receive the bearing insert. The bearing insert has an articular surface and a plate-contacting surface opposite the articular surface and the latch is adapted for disposal through a hole in the bearing insert. The system is adapted so that when the plate-contacting surface of the bearing insert is disposed on the baseplate and the latch is disposed through the hole in the bearing insert, the latch is rotatable from a first position to a second position. In the first position, the bearing insert is removable from the baseplate. In the second position, the bearing insert is held in place on the baseplate.

  • Publication number: 20240032946
    Abstract: A system is disclosed to support installation of a prosthetic joint or a prosthetic component. The system includes at least one sensor to measure a parameter. The system uses one or more patient specific instruments in conjunction with a tensor to make one or more bone cuts. The patient specific instruments and tensor make the bone cuts such that an installed prosthetic joint is aligned, balanced, loaded correctly, and positioned optimally for performance and reliability. The use of the tensor simplifies the workflow required when using the patient specific instruments. In one embodiment, the patient specific instruments are bone cutting jigs configured for the patient anatomy.

  • Publication number: 20230310033
    Abstract: A tool for implanting an orthopedic implant upon a bone includes a body defining an implant socket for releasably retaining an implant and a drill guide opening into the implant socket. The body is an insert receivable in an insert socket of a movable end of the tool. The tool also includes a tip toward which the implant socket faces and opposedly movable relative to the body. The tool is usable in a process that includes clamping a bone between the tip and the implant while the implant is retained in the implant socket. While the bone is clamped, a drill is driven through the drill guide to produce a hole in the bone.
