Abstract
A femoral head arthroplasty system can comprise a femoral prosthesis comprising a mounting plate having a first side and an opposed second side. An adapter can extend from the second side of the mounting plate. An implant body can extend from the first side of the mounting plate. The implant body can extend from the mounting plate by a distance no greater than 90 mm. The femoral head arthroplasty system can further comprise a femoral head replacement having a generally spherical surface and comprising a recess that is shaped to complementarily receive the adapter of the femoral prosthesis.
Claims20
A femoral head arthroplasty system comprising:
- a femoral prosthesis comprising:
- a mounting plate having a first side and an opposed second side, wherein the mounting plate is configured to couple to mounting hardware, and
- an implant body extending from the first side of the mounting plate, wherein the implant body extends from the mounting plate by a distance no greater than 90 mm;
- and
- a femoral head replacement having a generally spherical surface,
- wherein one of the femoral prosthesis and the femoral head comprises an adapter, and wherein the other of the femoral prosthesis and the femoral head defines a recess that is complementarily shaped to receive the adapter.
A kit comprising:
- a femoral prosthesis comprising:
- a mounting plate having a first side and an opposed second side;
- mounting hardware that is configured to couple to the mounting plate;
- an adapter extending from the second side of the mounting plate;
- and
- an implant body extending from the first side of the mounting plate, wherein the implant body extends from the mounting plate by a distance no greater than 90 mm;
- and
- a plurality of femoral head replacements, each femoral head replacement having a generally spherical surface and comprising a recess that is shaped to complementarily receive the adapter of the femoral prosthesis, wherein each femoral head replacement of the plurality of femoral head replacements differs from every other femoral head replacement of the plurality of femoral head replacements in size or material.
