Title (EN) PROSTHESIS OF THE HIP- OR KNEE-JOINT ANCHORED WITH A PRESTRESSING ELEMENT
(FR) PROTHESE POUR L'ARTICULATION DE LA HANCHE OU DU GENOU ANCREE A L'AIDE D'UN ELEMENT DE PRECONTRAINTE
Abstract:
(EN) Prostheses of the hip and the knee joint, of which both components are anchored into the bone with prestressing tendons (5) and by interposition of a joint. The anchorage system of the prostheses for the femoral part of the hip joint prosthesis and for both parts of the knee joint prosthesis consists of: (a) the sockets (3, 6) for the spheric end of the prestressing tendons on both components of the prostheses for the neutralization of tension forces, (b) the prestressing tendons, (c) the mechanism for bone protection, anchorage and fixing of the prestressing. The acetabulum part of the hip joint prosthesis is anchored into the bone of the pelvis with prestressing tendons.
(FR) Prothèses pour l'articulation de la hanche et du genou, les deux composants étant ancrés dans l'os à l'aide de tendons de précontrainte (5) et par intercalation d'un élément d'articulation. Le système d'ancrage utilisé pour les prothèses de la partie fémorale de l'articulation de la hanche et pour les deux parties de la prothèse de l'articulation du genou comprennent: (a) les cavités articulaires (3, 6) destinées à recevoir l'extrémité sphérique des tendons de précontrainte sur les deux composants des prothèses pour neutraliser les efforts de traction, (b) les tendons de précontrainte, (c) le mécanisme de protection des os, d'ancrage et de fixation du système de précontrainte. La partie acétabulaire de la prothèse de l'articulation de la hanche est ancrée dans l'os du bassin à l'aide de tendons de précontrainte.
