ABSTRACT:
An improved acetabular cup prosthesis has a cup body with correspondingly shaped inner convex and outer concave surfaces. A polymer liner fits and attaches to the cup at the concave surface. The inner convex surface is highly polished and mirror-like, for retarding debris generation with the polymer liner and allowing optical pattern inspection. A plurality of bores can be provided, 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.
