Title (DE) FEMURKOMPONENTE FÜR EINE HÜFTENDOPROTHESE
(EN) FEMUR COMPONENT FOR A HIP ENDOPROSTHESIS
(FR) COMPOSANT FEMORAL POUR ENDOPROTHESE DE LA HANCHE
Abstract:
(DE) Die Femurkomponente für eine Hüftendoprothese weist ein zur Einführung in den Markraum des Femurs bestimmtes distales Ende (1), eine proximale Schulterpartie (2) mit Hals (3), einen zwischen Schulterpartie (2) und Ende (1) liegenden Schaftteil (4) mit Längsachse (5) und Länge (L), sowie eine, im proximalen, in die Schulterpartie (2) übergehenden Drittel des Schaftteils (4) angebrachte, peripher umlaufende Nut (6) auf. Die Nut (6) ist über zwei auf der Oberfläche der Schulterpartie (2) verlaufende Kanäle (7) mit der proximalen Zone (8) der Schulterpartie (2) verbunden. Die Kanäle (7) gestatten eine lokale Zementapplikation im proximalen Bereich des Femurs. Im weiteren ermöglichen diese Kanäle ein Entweichen des überschüssigen, bei der Implantation der Femurkomponente im Markraum des Femurs vorhandenen Knochenzementes.
(EN) The femur component for a hip endoprosthesis has a distal end (1) destined for introduction into the femur medullary space, a proximal shoulder section (2) with a neck (3), a shaft section (4) between the shoulder section (2) and end (1) with longitudinal axis (5) and length (L), and a peripheral groove (6) in the proximal third of the shaft section (4) which merges into the shoulder section (2). The groove (6) is linked to the proximal zone (8) of the shoulder section (2) via two channels (7) on the surface of the shoulder section (2). The channels (7) facilitate local application of cement in the proximal region of the femur. They also allow excess bone cement, present in the femur medullary space when the femur component is implanted, to escape.
(FR) L'invention concerne un composant fémoral pour endoprothèse de la hanche présentant une certaine extrémité distale (1) destinée à être introduite dans la cavité du fémur renfermant la moelle, une partie épaulement (2) proximale avec un col (3), une partie tige (4) située entre la partie épaulement (2) et l'extrémité (1), présentant un axe (5) longitudinal et une longueur L ainsi qu'une rainure (6) périphérique pratiquée dans le tiers proximal de la tige (4) qui se transforme en épaulement (2). La rainure (6) est reliée à la zone proximale (8) de l'épaulement (2) par deux canaux (7) situés à la surface de l'épaulement (2). Les canaux (7) permettent l'application locale de ciment dans la zone proximale du fémur ainsi que l'échappement de l'excédent de ciment osseux se trouvant la cavité du fémur renfermant la moelle lors de l'implantation de la composante fémur.
