Abstract:
A surgical tool and method used to extract an acetabular cup from an acetabulum with minimal or no bone damage even if there has been significant bone ingrowth prior to the extraction process. The tool is designed for use with a reverse hip prosthesis wherein the acetabular cup comprises a stem extending from its concave surface and an acetabular ball is affixed to the stem. The tool is rotated on the ball and a blade is thereby caused to rotate adjacent or in close proximity to a convex surface of the cup in a position between the acetabular bone and the cup, thereby separating the cup from the bone.

Claim (Index 1):
A surgical tool adapted for removing an acetabular cup from an acetabulum wherein the acetabular cup is a component of a reverse hip prosthesis and comprises an acetabular ball affixed to a stem which extends from a concave surface of the acetabular cup, the surgical tool comprising:\n a shaft; an extractor cup affixed at its proximal end to a distal end of the shaft, the extractor cup having at its distal end a concave surface sized to articulate on the acetabular ball; and a blade having a proximal end affixed to the shaft and a distal portion sized to move adjacent or in close proximity to a convex surface of the acetabular cup, the convex surface of the acetabular cup being in contact with the acetabulum.
