Abstract

Cette invention se rapporte au domaine de la pose d'endoprothèses pour l'articulation coxo-fémorale. L'embase de cette endoprothèse sans ciment se présente sous forme d'une tige comportant plusieurs côtés, laquelle tige s'élargit de manière continue depuis son extrémité distale vers le haut et sur ses quatre côtés. La partie proximale de la tige comprend une broche avec un embout conique. L'axe de la broche et l'axe de la tige définissent un angle obtus, tandis que le côté médian dans la partie proximale présente une transition courbe et régulière en direction de la broche. La section de la tige, au moins dans la partie distale, se présente sous forme d'un trapèze isocèle dont la base la plus petite se trouve sur le côté médian tandis que la base la plus grande se trouve sur le côté latéral. L'angle de convergence de ces deux côtés est plus important que l'angle de convergence du côté dorsal et du côté antérieur. Le côté médian, dans la partie proximale, comprend des chanfreins courbes et réguliers qui sont orientés vers le côté dorsal et le côté antérieur, et dont la taille augmente en direction de la broche. Le côté dorsal et le côté antérieur, dans la partie proximale, comportent des évidements d'une profondeur constante dans lesquels sont fixées des plaques planes et inamovibles faites d'un matériau poreux et biologiquement inerte. L'épaisseur de ces plaques est supérieure à la profondeur des évidements d'une valeur au moins égale à la taille moyenne des pores, et représente de 20 à 200 fois la taille moyenne des pores.
