ABSTRACT:
The present invention is directed to an acetabular cup prosthesis for implantation into a pelvic bone. A cup having a cavity for receiving a femoral head is formed of a polymeric material having a predetermined tensile strength. A backing is disposed about and attached to the polymeric cup. The backing has a porous construction defining interstitial pores, with the pores being sized to receive a portion of the polymeric cup therein and adapted for allowing ingrowth of the bone therein. The portion of the polymeric cup received within the pores results in an interface strength between the polymeric cup and the backing which is substantially equal to the tensile strength of the polymeric material.
