ABSTRACT:
The socket body has an exterior surface which tapers in one direction while anchoring beads on the exterior surface taper in an opposite outward direction. The beads serve to anchor the body within a pelvis. In addition, cross ribs are formed on the anchoring beads with at least some of the ribs being elastic. Upon insertion of the socket, the ribs bend in a direction opposite to the direction of insertion. The two oppositely directed anchoring tapers of the socket body and the beads provide a firm fit of the socket body in a pelvis with a cement-free anchoring. Also, the bent ribs tend to resist withdrawal of the socket from the pelvis.
