Abstract
A humeral implant configured for implantation at a distal end portion of a humerus. The humeral implant can be configured to articulate with a portion of an ulna. The humeral implant may include a body portion having a first end, a second end, and a side surface that extends between the first end and the second end, where the side surface includes a concave region that defines a first cross-sectional diameter that is a minimum cross-sectional diameter of the body portion.
Claims25
A humeral implant configured for implantation at a distal end portion of a humerus, the humeral implant comprising:
- a body portion that is made entirely of pyrocarbon and comprises:
- a first end and a second end;
- a side surface that extends between the first end and the second end, wherein the side surface comprises a concave region that defines a first cross-sectional diameter that is a minimum cross-sectional diameter of the body portion;
- wherein the first end having a second cross-sectional diameter that is larger than the first cross-sectional diameter;
- and
- wherein the second end having a third cross-sectional diameter that is larger than the first cross-sectional diameter.
An elbow prosthesis comprising:
- a spool-shaped body extending along a longitudinal axis configured to be positioned at a trochlea portion of a distal humerus, the spool shaped body is made entirely of pyrocarbon and comprises:
- a first end;
- a second end;
- and
- a concave surface extending between the first end and the second end, the concave surface configured to receive a trochlea groove of an ulna.
The elbow prosthesis of claim 19, wherein the first end of the spool-shaped body is at a first end of the elbow prosthesis and the second end of the spool-shaped body is at a second end of the elbow prosthesis.
