  • the femoral component has a shaft for anchoring in a medullary canal of the femur and a neckpiece arranged thereon, which carries the bearing head.

  • the stem shape is thus adapted to the inner contour of the medullary canal in the femur so that when implanted shaft thanks to the S-shape, a high degree of safety against unwanted rotations of the prosthesis to the femur is achieved.

  • the other basic concept is a form shank, which differs significantly over its entire length from a round shape, wherein it has in its lower portion substantially an oval cross-section. Due to the highly non-circular shape of the medullary cavity in the femur can not be prepared by drilling for implantation, but it is rather a complementary to the shape of the shaft forth ⁇ working out a specific cavity structure required. For this purpose a series of exact form rasps are provided with which the medullary canal is widened in the femur successively until finally the final kom ⁇ -complementary to the shape of the shank design of the cavity is reached.
  • the ovality at the lower end of the shaft is varied so that a chamfer at the late ⁇ eral side is formed. This facilitates the insertion into the precisely shaped receiving cavity in the medullary canal, especially in its upper and middle area.

Abstract

L'invention concerne une prothèse de hanche fémorale comprenant une tige (2), adaptée pour être ancrée dans le fémur (9), qui possède un côté médial (M) et un côté latéral (L) opposé ainsi qu'une extrémité distale (22) et une extrémité proximale (25) sur laquelle est disposée une partie de col (3), orientée en direction médiale, qui comporte un élément de support (4) destiné à se loger de manière mobile en pivot dans l'acétabule. Entre son extrémité proximale (25) et son extrémité distale (22), la tige (2) présente une courbure en S. La tige (2) possède une section transversale ronde dans sa zone distale (21) et elle comporte à son extrémité distale (22) un chanfrein (4) qui s'étend sur une longueur correspondant à la largeur de la tige dans la zone distale (21). La combinaison du chanfrein dans la zone distale et d'une section transversale ronde a un effet atraumatique et elle permet d'obtenir un bon ancrage en même temps qu'une facilité d'introduction améliorée.
