Abstract:
A surgical instrument for separating a femoral cup or a femoral ball from a femoral implant wherein the cup or ball is affixed to the implant by means of a Morse taper. A tapered wedge in the form of a two pronged fork is provided at the distal end of the instrument for placement between the cup or ball and the femoral implant. Then the proximal end of the instrument is struck with a hammer to separate the cup or ball from the femoral implant. The surgical instrument of the invention enables a surgeon to remove the cup or ball without pulling on the femoral implant and, thereby, without disrupting any bone ingrowth in the implanted femoral implant.

Claim (Index 3):
A method of using the surgical instrument of  claim 1  comprising contacting the distal end of the wedge with the proximal end of the femoral implant and the outer convex surface of the femoral cup or femoral ball adjacent the neck so that the lower surface of the tapered prongs is in contact with the proximal end of the femoral implant and the upper surface of the tapered prongs is in contact with the convex surface of the femoral cup or femoral ball and the neck is partially received within the space between the prongs, tapping the proximal end of the handle with a hammer to cause the femoral cup or ball to be lifted upwardly relative to the femoral implant so that said cup or ball is no longer affixed to the femoral implant by means of the Morse taper.
