Abstract
A wrist joint prosthesis comprises a metal radial component and a metal metacarpal component connected by a metal axle and providing triaxial motions that are comparable to those of the anatomical wrist joint and restraint of excessive motions. Energy is absorbed and shock loads are minimized by the interposition of a bearing member between the radial and metacarpal components and a bearing sleeve of polymeric material over the axle.
