ABSTRACT:
An impactor/extractor holder for a femoral trial and/or a knee implant to hold and guide those items onto the resected end of a femur. The impactor/extractor holder comprises two opposed clamping arms for gripping the opposite outer edges of the trial and/or implant, and an abutment table movable relative to the clamping arms so as to be capable of being advanced against the outer surface of the trial and/or implant after the sides have been clamped by the clamping jaws. The abutment table has a cushioning surface for contacting the trial and/or implant which is adapted not to damage the outer surface of the implant or trail. A threaded mechanism is provided for moving the abutment table relative to the clamping jaws to advance the cushioning surface of the abutment table against the outer surface of the implant or the trial to securely and rigidly lock the trial or implant on the impactor/extractor holder. A trial rasp is also disclosed.
