| 摘要 |
A profiled shaft for anchoring a hip-joint prosthesis in the femur is disclosed, with a shaft section and a fixation section that is formed at the end of the shaft section and that serves for the fixation of a spherical joint head, wherein the shaft section on the lateral surface in the proximal region merges with a trochanter wing at the edges of which beveled surfaces are formed. The essential point of the invention is that the angle formed between the plane of a beveled surface the plane of the adjacent surface is smaller than 135° and larger than 90°. In a construction of this kind the advantage of an improved filling of the empty space in the trochanter-wing region is achieved.
