Abstract
A system for reconstructing a patient's distal ulnar joint includes a prosthetic ball joint having elements for implanting, respectively, in a distal ulnar bone fragment and a distal ulnar stump from which the fragment has been separated, a bone screw by which the fragment is fused to the distal radius also serving to anchor the corresponding joint element. Also disclosed is a method for implanting by excising the segment of the ulnar neck, implanting the ball member, fusing the ulnar fragment in fixed relation to the distal radius with the first bone screw extending through the ball member for anchoring same with the fragment, implanting the socket member on the ulnar stump, and snapping the ball member into engagement with the socket member 28.
