ABSTRACT:
A modular component for a prosthetic implant includes a first member, in the form of a tibial tray member, and a second member, in the form of a stem member, joined together by the insertion of a tapered post on the stem member into a tapered receptacle in the tibial tray member, the relative tapers and relative dimensions of the post and the receptacle being such that the inner surface of the receptacle is seated against the outer surface of the post at least adjacent one end of the receptacle and the corresponding end of the post, and a stabilizing mechanism urges annular segments of the post, adjacent the other end of the post, toward engagement with the inner surface of the receptacle adjacent the corresponding other end of the receptacle to stabilize the connection between the tibial tray member and the stem member.
