ABSTRACT:
An improved stem portion of a joint prosthesis for replacing a damaged or diseased skeletal joint is provided by the subject invention, wherein a series of sections of elastomeric material attached to a rigid material are disposed one on top of the other in a staggered or offset configuration to form the stem. The offset is such that alternate sections of elastomer and rigid material contact selected locations of the bone within the medullary canal to firmly secure the prosthesis therewithin for resisting dislocation particularly during the early stages of postoperative rehabilitation.
