Femoral head intramedullary stemmed implant. A historical prospective

A historical review reveals that McBride may have been the first to use a femoral head intramedullary stemmed hip implant. It had a threaded stem and limited use. Eicher may have been the first to develop and use the smooth intramedullary stemmed femoral implant with a calcar collar, which was the forerunner of implants used today. Moore subsequently developed the self-locking intramedullary stemmed femoral implant with a calcar collar. Shortly thereafter, Thompson introduced a similar prosthesis. These four surgeons pioneered the development of the intramedullary stemmed femoral head prosthesis, which has been a key contribution to modern hip reconstruction.
