ABSTRACT:
An orthopedic prosthesis comprising a polymeric cup member for use in a ball and socket joint is disclosed. The cup member may include several advantageous features such as a multi-directional and multi-planar channel having an undercut area that provides a mechanical lock between the cup member and a fixation material for enhanced fixation. The cup member may further comprise a plurality of spacers for ensuring an even mantle of fixation material between the cup member and the bone, a series of divots for enhancing fixation, a locating feature that permits a physician to visualize and locate the cup member in the socket of the patient's bone on appropriate medical equipment, and a lead-in chamfer located between a terminal edge and an interior surface of the cup member. Further, the terminal edge of the cup member may comprise a planar rim or may alternatively comprise a hood located distally from said terminal edge.
