title: Two component femoral head prosthesis-endoprosthesis S-73.
abstract: A two component femoral head prosthesis consisting of a metal femoral stem with a small low friction head and HDP cup fitting the acetabulum was used in 80 patients with intra-articular femoral neck fracture; this allowed immediate and relatively painless ambulation and weight bearing. Most of the movement occurs between the stem and cup, so the pain in the joint is eliminated. Except for two cases of technical error there were no signs of instability. It appears that this kind of endoprosthesis may be an answer to the problem of early and painless ambulation in elderly patients with subcapital femoral fracture.
