摘要
A surgical tool for extracting an acetabular ball from an acetabular cup in an implanted hip prosthesis wherein the from 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 ingrowth because the tool maintains pressure on the cup while exerting an opposing pressure pulling on the ball.
