Abstract:
A surgical tool for extracting an acetabular ball from an acetabular cup in an implanted hip prosthesis wherein the acetabular ball is affixed by means of a Morse taper to a stem extending from bottom of the concave portion of the acetabular cup. The surgical tool enables a surgeon to remove the ball without pulling on the acetabular cup and without disrupting any bone in-growth because the tool maintains pressure on the cup while exerting an opposing pressure pulling on the ball.

Claim (Index 6):
A method of using the surgical tool of  claim 1  comprising the steps of:\n disposing the jaws over an acetabular ball which affixed by means of a Morse taper to a stem extending from a concave surface of the acetabular cup and contacting the circumferential bell edge of the bell shaped element with the circumferential cup edge of the acetabular cup and then pulling the jaw stem in the proximal direction while pushing on the acetabular cup in a distal direction until the acetabular ball is released from the stem.
