A multi-component wrist joint assembly incorporated into reconditioned end surfaces established between an upper radius bone and at least opposing lower scaphoid and lunate bones. A first component is anchored into the upper radius reconditioned end surface and exhibiting a first exposed support surface. A second component is anchored into the lower scaphoid and lunate reconditioned end surfaces and exhibiting a second exposed support surface. A spherical shaped intermediate component is supported in at least one of eccentric or rotational fashion between the first and second anchored components.
