Anchored shaft for a femoral prosthesis

Abstract

Abstract The medial, narrow side (6) of an anchoring shaft (1) for a femoral head prosthesis is provided with a slot (9) slightly under the collar (7) which separates the shaft (1) from the prosthesis neck (4). This slot (9) widens laterally into the body of the shaft to form a bubble- shaped recess (10). The recess (10) is filled with an elastic filler (13). <??>With this new construction, the elasticity of the shaft (1) in the proximal area is adapted to that of the cortical bone. In this way it is possible to ensure an intimate and constant contact between the prosthesis collar (7), which bears on the cortical edge of the resection plane, and the cortex of the bone. <IMAGE>
