This invention relates to a joint prosthesis. The joint prosthesis has an anchoring means (1, 51, 100) arranged to be placed in a bone to rest against and be supported by an inside surface of the cortical bone layer. The anchoring means (1, 51, 100) may be placed in a bore along an extra medullary axis of a bone, such as the femur (F), and be supported by the cortical bone layer distal from the hip joint. Locking means (2, 2', 3, 3', 52, 106) are provided in order that the anchoring means (1, 51, 100) can be inserted through an inlet opening (Fi) and be supported by the inside surface (C) of the cortical bone wall adjacent the opening (Fi).
La présente invention se rapporte à une prothèse articulaire munie de moyens d'ancrage (1, 51, 100) conçus pour être placés dans un os pour s'y appuyer contre une surface interne de la couche osseuse corticale. Ces moyens d'ancrage (1, 51, 100) peuvent être placés dans un trou le long d'un axe médullaire d'un os, tel que le fémur (F), et soutenus par la couche osseuse corticale distale de l'articulation de la hanche. Des moyens de verrouillage (2, 2', 3, 3', 52, 106) permettent d'insérer les moyens d'ancrage (1, 51, 100) à travers un orifice d'entrée (Fi) de sorte qu'ils soient soutenus par la surface interne (C) de la paroi osseuse corticale adjacente audit orifice (Fi).
