Abstract
A ball and socket joint prosthesis (10) for use in arthroplasty is provided. The prosthesis includes a body (32) for implantation at least partially within the medullary canal (24) of a long bone (12). The long bone defines trabeculae (60) in the proximal cancellous bone (22) and lamellae (71) in the cortical bone (65). The body includes a proximal portion (52) thereof and a distal portion (54). The proximal portion has a medial periphery (69) and includes surface features (64) on a substantial portion of its proximal portion. The surface features are positioned to optimally transfer load from the prosthesis to the long bone.
