Claim:
A joint prosthetic component comprising: a proximal arm and a distal arm; and a joint member interposed between the proximal arm and the distal arm, the joint member configured to permit flexion motion between the proximal arm and the distal arm, the joint member including a concave dorsal surface and a concave palmar surface, wherein the concave dorsal surface has a proximal arcuate portion and a distal arcuate portion defined therein, wherein the concave dorsal surface further has a planar bottom wall interposed between and connecting the proximal arcuate portion and the distal arcuate portion, wherein the concave palmar surface has only a single arcuate portion, and wherein the single arcuate portion of the concave palmar surface is positioned between the proximal arcuate portion and the distal arcuate portion of the concave dorsal surface in the proximal-distal plane.
