ABSTRACT:
A stem-type femoral prosthesis has a distal tip with a fixation-resistant finish on the external peripheral surface of the distal tip so that the distal tip remains uncoupled from the femur upon implant of the prosthesis and during use. The distal tip is selectively removable and replaceable to enable a choice of size combinations in the joined stem and distal tip of the prosthesis for increased ease in the fitting of both the proximal and the distal portions of an appropriate prosthesis.
