ABSTRACT:
A stem for a femoral hip-joint endoprosthesis comprises a shaft which is substantially rectangular in cross section, with a distal and a proximal end. The distal end tapers substantially conically and the proximal end (16) comprises an insertion means and an extraction means for the insertion and for the extraction of the stem into a marrow space of a femur. A cone is provided to receive a joint ball, the cone being connected to the proximal end of the shaft by way of a neck. The insertion means and the extraction means at the proximal end of the shaft are positioned substantially on the median long axis of the stem so that force transmission during insertion and extraction is coaxial.
