ABSTRACT:
A hingeless elbow prosthesis including humeral and ulnar implants, in which the head of the humeral implant has a convex medial condylar formation presenting a smooth curved trochlear groove in the shape of part of a helix and providing a bearing surface for a head of the ulnar implant and in which the ulnar implant presents a condylar head contoured to fit into the trochlear groove, so that as the ulnar implant pivots around the humeral implant, with the condylar head mating with the trochlear groove, the ulnar implant moves along the pivotal axis and the ulnar performs the required valgus in extension and varus in flexion.
