Patent ID: 8556986

Claim:
An acetabular prosthetic device for use with a prosthetic hip implant comprising an acetabular cup coupled to at least one acetabular augment by a corresponding augment coupling element to anchor said acetabular prosthetic device to the ilia bone: said acetabular cup comprises a shell having an apex and including a substantially concave inner surface to rotatably receive a substantially spherical portion of the prosthetic hip implant therein and a substantially convex outer surface having at least one groove including an enlarged inner portion and a reduced outer portion formed therein to receive at least a portion of said augment coupling element; said acetabular augment comprises an augment body including a substantially concave shell engaging surface having a coupling aperture formed therethrough and configured to engage said substantially convex outer surface of said shell and a bone engaging surface having a acetabular aperture formed therethrough and configured to engage the ilia bone; said augment coupling element comprises an enlarged distal inner member disposed within said enlarged inner portion of said groove to retain said enlarged distal inner member therein and said reduced proximal member at least partially disposed within said reduced outer portion of said groove and extending outwardly from said reduced outer portion of said groove; said augment coupling element longitudinally movable within said groove to slidably move said bone engaging surface into engagement within the ilia bone; said acetabular prosthetic device further including an anchor fastener extending through said acetabular aperture to anchor said bone engaging surface of said acetabular augment to the ilia bone; and when said augment coupling element is moved toward said apex until said bone engaging surface engages the ilia bone; and said augment coupling element further including a securing fastener to engage said reduced proximal member to secure said substantially concave surface of said acetabular augment to said substantially convex outer surface of said shell of said acetabular cup when said augment coupling element is operatively positioned along said groove when said bone engaging surface anchored to the ilia bone.
