Title (EN) ENDOPROSTHESIS FOR A FEMORAL HIP JOINT
(FR) ENDOPROTHESE POUR L'ARTICULATION COXO-FEMORALE
Abstract:
(EN) An endoprosthesis for a femoral hip joint comprises a stem (1) with a collar (3) which bears against a resected bone surface and has a blocking cone (4) on which the ball head (5) is positioned. A screw (12) which grips the prosthesis as a tensioning stay passes through a lateral bore extending obliquely downward and outward through the femur. The prosthesis stem is designed to permit cementless fixation and to prevent crack formation in the femur due to rigidity of the stem, even under extreme loads. To this end, the prosthesis stem (1) is lodged in a mating fit in a medullary nail (7) driven into the medullary canal, and the distal region of the prosthesis stem (1) is elastic.
(FR) Une endoprothèse pour l'articulation coxo-fémorale comprend une tige (1) ayant un collet (3) qui s'appuie sur une surface de résection de l'os et qui est pourvu d'un cône de blocage (4) et de support de la rotule (5) de l'articulation, et une vis de serrage (12) qui s'engage dans la prothèse à titre d'élément de tension et traverse un alésage latéral du fémur qui s'étend obliquement vers le bas et vers l'extérieur. Le support est conçu de sorte que la tige de la prothèse tienne dans le fémur sans devoir être cimentée et sans provoquer de fêlures du fémur dues à la rigidité de la prothèse même sous des sollicitations extrêmes. A cet effet, la tige (1) de la prothèse s'adapte dans une cheville médullaire (7) introduite dans la cavité médulllaire. En outre, la zone distale de la tige (1) de la prothèse est élastique.
