Abstract

A device for embedding in bone, in particular as a femoral hip-joint prosthesis, comprises a head part, a stem to be anchored in the bone, and a support collar terminating the stem at the head end. In order to make it easy for the surgeon, on reoperation, to remove the prosthesis stem from the bone tissue, the support collar can be removed. In addition, it can be combined with an anchor for attachment to the greater trochanter. By this means, on the one hand, the support collar is fixed in the envisaged position and, on the other hand, the greater trochanter participates with the adjacent lateral areas of the bone in taking up the load.
