Abstract
A femoral impactor-extractor and method includes a body having an elongated passageway extending from a proximal end to a distal end, an elongated post positioned in such passageway for longitudinal movement therein and extending from a threaded proximal end to a distal end having an enlarged flange with a greater length than breadth. The proximal end of the elongated post is threaded and threadedly engaged to a rotatable handle. Rotation of the handle moves the elongated post and its flange in a proximal direction to clamp the femoral knee prosthesis between the ends of the flange and contoured surfaces which engage the articulating surfaces of the respective condylar portions of the prosthesis.
