ABSTRACT:
An improved acetabular cup prosthesis has a cup body with a plurality of bores extending between an inner concave surface and an outer convex surface, wherein the bores can function as drill guides for providing alignment in the drilling of surgical openings after the acetabular cup body is placed in a patient. A plurality of pegs or spikes have proximate end portions that have connection members for forming connections with the bores, and distal end portions that can register into the drilled surgical openings.
