The first concave surface has a plurality of arcuate portions defined therein. The first and second concave surfaces are located on opposing sides of the joint member.
Claims19
A joint prosthetic component comprising:
- first and second arms;
- and
- a joint member interposed between the first and second arms, the joint member configured to permit flexion motion between the first and second arms, the joint member including a first concave surface and a second concave surface, the first concave surface having a plurality of arcuate portions defined therein.
A joint prosthetic component comprising:
