[Experiences with hip joint endoprosthesis model PM for cement free implantation].

This is a report about the experiences made with a new hip prosthesis for cementless fixation.

However, as for all other prostheses for cementless fixation, an exact operating technique is indispensable for thorough adaption of the inner femur surface to the shape of the prosthesis.
