ABSTRACT:
The prosthesis includes two components having biocompatible metal balls at one end thereof. The radial component is secured by an affixation to the distal radius. The metacarpel component is implanted by a pair of affixation stems into the second and third metacarpel bones of the hand. The balls are rotatably captured between a pair of cutout plastic spheroidal blocks clamped together by a biocompatible metal shell, which is spacially compatible within the wrist area.
