      A new endoprosthesis for the treatment of subcapital fractures is described. It is hemispherical with a high density polyethylene (HDP) core which is snap-fitted onto a Charnley-type femoral prosthesis. The aim is to prevent acetabular erosion by its virtual lack of movement of the cartilage-metal interface. If this should occur then conversion to a total hip is readily performed without removing the femoral stem. So far 14 have been inserted without any complications. In fact, they are easily mobilized with very little pain.
