Arthroplasty components include an articular surface and a bone-facing surface. The bone-facing surface includes a concave arrangement of planar surfaces which converge as they approach a middle portion of the articular surface. Instruments and implantation methods are also disclosed.
Claims20
An arthroplasty prosthesis comprising:
- an articular surface;
- and
- a bone-facing side opposite the articular surface;
- wherein the bone-facing side comprises a concave arrangement of at least three planar surfaces, wherein the at least three planar surfaces converge toward the articular surface.
1 more element
An arthroplasty prosthesis comprising:
- an articular surface;
- and
- a bone-facing side opposite the articular surface, wherein the bone-facing side comprises a first planar surface, a second planar surface, and a third planar surface, wherein the first planar surface intersects the second planar surface along a first line, wherein the second planar surface intersects the third planar surface along a second line, wherein the first and second lines intersect.
An arthroplasty prosthesis comprising:
- an articular surface;
- and
- a bone-facing side opposite the articular surface, wherein the bone-facing side comprises a socket with at least three planar side walls, wherein the at least three planar side walls taper inwardly as the socket extends from the bone-facing side toward the articular surface.
