Title (DE) MODULARE ENDOPROTHESE
(EN) MODULAR ENDOPROSTHESIS
(FR) ENDOPROTHESE MODULAIRE
Abstract:
(DE) Modulare Endoprothese, insbesondere Femurprothese, welche eine Konus-Steckverbindung aufweist, mit einem ersten Schaftelement (2) mit einer im wesentlichen konischen Bohrung (9), einem zweiten Schaftelement (3) mit einem im wesentlichen konischen, an die Bohrung (9) in dem ersten Schaftelement (2) angepaßten Zapfen (8) zur Verbindung der beiden Schaftelemente (2, 3), wobei das die Bohrung aufweisende, erste Schaftelement (2) zur Verringerung der bei einer Biegebeanspruchung am Mündungsrand der Bohrung (9) auftretenden mechanischen Belastung an ihrer Außenwand in der Nähe des Mündungsendes (9) eine umlaufende Einkerbung (15) aufweist.
(EN) A modular endoprosthesis, in particular femur prosthesis, with a conical plug connection, has a first shaft element (2) with a substantially conical bore (9), and a second shaft element (3) with a substantially conical dowel (8) that fits into the bore (9) in the first shaft element (2) for interconnecting both shaft elements (2, 3). In order to reduce mechanical stresses that occur at the edge of the mouth of the bore (9) when the prosthesis is flexurally stressed, the outer wall of the first shaft element (2) provided with the bore has a continuous notch (15) close to the mouth end (9).
(FR) L'invention concerne une endoprothèse modulaire, notamment une prothèse du fémur, avec une connexion conique à fiche, comprenant un premier élément allongé (2) pourvu d'un alésage sensiblement conique (9) et un deuxième élément allongé (3) pourvu d'une cheville (8) sensiblement conique adaptée à l'alésage (9) du premier élément allongé (2) pour relier mutuellement les deux éléments allongés (2, 3). Afin de réduire la sollicitation mécanique du rebord de l'ouverture de l'alésage (9) pendant des sollicitations en flexion, une gorge continue (15) est ménagée à proximité de l'extrémité de l'ouverture (9) dans la paroi extérieure du premier élément allongé (2) pourvu de l'alésage.
