Abstract: Prosthetic replacement of an elbow joint is accomplished using a humeral component having an articular surface comprising a concave surface in the coronal plane and a convex surface in the sagittal plane with such component being cemented along a superior U-slot to a surgically prepared humeral bone. The prosthesis also comprises an ulnar component having an articular surface defined by a convex surface in the coronal plane and a concave surface in the sagittal plane, its undersurface having a longitudinal keel and a dependent stem by which it is cemented to the surgically prepared ulnar bone. Optionally, the prosthesis may include a radial head component in the form of a dished button that can be cemented to the surgically prepared radial bone by a depending stem.

The prosthesis also comprises an ulnar component having an articular surface defined by a convex surface in the coronal plane and a concave surface in the sagittal plane, its undersurface having a longitudinal arcuate keel and a dependent stem by which it is cemented to the surgically prepared ulnar bone. Optionally, the prosthesis may include a radial head component in the form of a dished button that can be cemented to the surgically prepared radial bone by a depending stem.
