Abstract
An elbow prosthesis having a humeral component which substantially replicates the natural trochlear and capitellum convex bearing surfaces has been generated by computer analysis and may be fabricated by a computer controlled cutting and polishing device or may be made by precision casting from a 'best-fit' type generalized series of moulds. The prosthesis may be inserted from the medial side of the elbow after preparing the distal humerus to provide a smooth convex surface which fits closely to an inside concave surface of the prosthetic element. The centroidal longitudinal axis of said convex bearing surfaces is coincident with the centroidal longitudinal axis of the concave surface.
