A novel and improved elbow prosthesis and method of implanting same including a prosthesis system that has a retaining system. The joint prosthesis system can include an implant, and an alignment guide. The alignment guide can include a post member extending through a central axis of rotation in a prosthesis and a drill guide member having a first limiting member for limiting articular surface removal from a joint. The first limiting member can include a recessed guide for positioning the implant.

A trial orthopedic implant having a plurality of bearing component augments of differing heights, where each augment releasably, slidably connected to the trial implant.

There is disclosed herein radial head elbow prosthesis which is anatomically designed to improve anatomical conformity and function and reduce likelihood of dislocation. Depression centroid eccentricity and orientation and raised lateral bearing surface aspects of the present radial head improve tracking of the radial head prosthesis of the capitellum and reduce likelihood of dislocation thereof.

A radial head prosthesis for implantation in a distal radius. The implant includes a head portion and a stem portion. The stem portion has a cylindrical shaft and tapered tip. The head portion includes a recess for engagement with the stem portion. The head portion includes a first bearing surface for articulation with a humerus, and a second bearing surface for articulation with an ulna. The second bearing surface includes at least one concave and one convex portion immediately adjacent one another.
