Abstract

Abstract 1. A femoral head prosthesis whose head is disposed on a prosthetic neck (5) merging into an anchorage stem (1) anchorable in a bone cement bed (11), the substantially rectangular section stem extending in a continuous curvature into a conically narrowing distal end (2) which extends in the direction of the stem axis (3), characterized in that the thickness of the stem (1) widens stepwise initially to a maximum thickness on both sides and perpendiculary to a central plane (4) parallel to the wide sides, progressing in cross-section from medial to lateral, and decreases stepwise from this maximum thickness in at least one step to the lateral narrow side (14).
