ABSTRACT:
An improved acetabular prosthesis (14) is disclosed for use with a femoral head prosthesis (12). The acetabular prosthesis (14) comprises a cup (28) having, in use, sufficient strength to maintain its shape. The exterior surface of the cup (28) is substantially hemispherical. A coating (32) of sufficient thickness is provided on the exterior surface of the cup (28). The coating (32) is sufficiently deformable and has limited elastic memory to mold itself to the particular anatomic geometry or inner contour of the acetabulum. The coating (32) has grooves (36) on its external surfaces.
