Description
ELEMENT FEKORAL DE PROTHESE DE flANCHE
La présente invention concerne un élément fémoral de prothèse de hanche, du type comportant une tige destinée a être ancrée dans le canal médullaire du fémur réséqué et une embase qui reconstitue le col anatomique du fémur et présente une portée conique destinée recevoir et retenir une tête sphérique reconstituant la tète du fémur.
La présente invention concerne un élément fémoral de prothèse de hanche, du type comportant une tige destinée a être ancrée dans le canal médullaire du fémur réséqué et une embase qui reconstitue le col anatomique du fémur et présente une portée conique destinée recevoir et retenir une tête sphérique reconstituant la tète du fémur.
Dans ces éléments fémoraux connus de prothèse de hanche, l'embase fait, généralement, partie intégrante de la tige avec laquelle elle forme donc un ensemble monobloc.
Par ailleurs, le col anatomique d'un fémur présente généralement une antéversion d'environ 200.
En outre, - lors de la pose d'une prothèse de hanche, il est nécessaire de retendre le système musculaire en latéralisant le fémur.
I1 en résulte que, pour pouvoir réaliser des poses de protheses de hanche, en respectant l'antéversion droite ou gauche, décalées ou non selon quTil y a nécessité ou non de retendre les muscles, il est nécessaire de disposer de quatre types différents d'éléments fémoraux pour chaque taille de prothèse.
Etant donné qu'il est, généralement, prévu dix tailles différentes de prothèses, il est donc nécessaire de disposer de quarante implants différents.
Par la demande de brevet français nO 91.03150, on connais un élément fémoral pour prothèse de hanche visant a remédier a ces inconvénients en permettant de simplifier considérablement les stocks d'implants.
Dans cet élément fémoral, l'embase est apte à être fixée, de manière amovible et avec le calage angulaire désiré, à l'extrémité proximale de la tige.
Ainsi, il suffit de disposer de dix tiges et de quatre embases, à savoir, antéversée droite, antéversée gauche, décalée antéversée droite, et décalée antéversée gauche, pour remplacer les quarante éléments fémoraux habituellement nécessaires.
Dans cet élément fémoral, les moyens de fixation amovibles de 1'embase à l'extrémité proximale de la tige sont du type à cônes male et femelle, avec effet de coincement, éventuellement complété par vis coaxiale.
Si la liaison par emmanchement conique donne généralement satisfaction, elle présente, cependant, l'inconvénient de ne pas lutter assez efficacement contre la rotation de l'embase par rapport à la tige, de sorte qu'il est nécessaire de prévoir des moyens de calage angulaire de ces pièces. Dans l'élément fémoral précité, des moyens de calage angulaire de l'embase sur l'extrémité proximale de la tige sont prévus, ces moyens pouvant être constitués, tout simplement, par un ergot excentré porté par l'une de ces parties et engageable dans un logement prévu, pour le recevoir, dans l'autre partie.
La présente invention vise à simplifier la fabrication de cet élément fémoral en supprimant les moyens auxiliaires de calage de la partie cervicale et de la tige.
A cet effet, dans l'élément fémoral qu'elle concerne et qui est constitué de deux pièces, respectivement une tige et une embase, assemblables l'une a l'autre par engagement d'un pion tronconique a faible pente, en saillie sur la face d'assemblage de l'une, dans un puits tronconique de forme complémentaire débouchant dans la face d'assemblage de l'autre, la section transversale du pion et du puits est elliptique, le grand axe de l'ellipse étant contenu dans le plan défini par l'axe de la tige et celui de l'embase, après assemblage, tandis que sont prévus, d'une part, un jeu de plusieurs embases, de longueurs de col différentes, décalées ou non décalées et/ou antéversées et d'autre part, un jeu de plusieurs tiges de différentes dimensions.
De toute façon, l'invention sera bien comprise, à l'aide de la description qui suit, en référence au dessin schématique annexé- représentant, à titre d'exemple non limitatif, une forme d'exécution de cet élément fémoral
Figure 1 est une vue de face en élévation de la tige seule
Figure 2 en est une vue en bout montrant sa face d'assemblage destinée à recevoir une embase ;
Figure 3 est une vue de côté en élévation de l'élément fémoral complet ;
Figure 4 est une vue en coupe transversale suivant

Figures 5 et 6 sont des vues respectivement de face en élévation et de côté montrant une embase normale ;
Figures 7 et 8 sont des vues similaires aux figures 5 et 6 montrant une embase décalée
Figures 9 et 10 sont des vues similaires aux figures 5 et 6 montrant une embase antéversée ;
Figures 11 et 12 sont des vues similaires aux figures 5 et 6 montrant une embase décalée antéversée.
Figure 1 est une vue de face en élévation de la tige seule
Figure 2 en est une vue en bout montrant sa face d'assemblage destinée à recevoir une embase ;
Figure 3 est une vue de côté en élévation de l'élément fémoral complet ;
Figure 4 est une vue en coupe transversale suivant
IV-IV de figure 3 ;
Figures 5 et 6 sont des vues respectivement de face en élévation et de côté montrant une embase normale ;
Figures 7 et 8 sont des vues similaires aux figures 5 et 6 montrant une embase décalée
Figures 9 et 10 sont des vues similaires aux figures 5 et 6 montrant une embase antéversée ;
Figures 11 et 12 sont des vues similaires aux figures 5 et 6 montrant une embase décalée antéversée.
Comme le montre plus particulièrement la figure 3, cet élément fémoral est du type constitué de deux pièces, à savoir une tige 2 et une embase 3 assemblées l'une a l'autre suivant un plan d'assemblage 4.
La tige 2, qui présente une partie distale 2a cylindro-conique et une partie proximale 2b s'élargissant d'avant en arrière et de l'intérieur vers l'extérieur en étant aplatie, est destinée a être engagée dans le canal médullaire du fémur réséqué du patient.
Comme montré a la figure 1, la partie distale 2a comporte un galbe anatomique d'un côté ou de l'autre suivant qu'il s'agit dune prothèse droite ou gauche.
La partie distale 2a comporte une fente axiale 5 à son extrémité, pour conférer à celle-ci une certaine élasticité. Cette partie distale 2a est sablée et anodisée. La partie proximale 2b est revêtue d'alumine et comporte des rainures profondes 6 pouvant recevoir des greffons lors d'éventuelles reprises. Des plats 7 disposés de part et d'autre des rainures 6 assurent la stabilité de la prothese.
L'embase 3, qui est destinée à être assemblée à la tige 2, porte un doigt tronconique 3a destiné a recevoir une sphère 8 dont la fonction est de remplacer la tête sphérique du fémur.
Dans cet exemple, 1'embase 3 est assemblée a la tige 2 par coincement conique d'un pion tronconique 9 en saillie sur la face d'assemblage 4a de la tige 2 dans un puits tronconique 10 de forme complémentaire débouchant dans la face d'assemblage 4b de l'embase 3.
Après assemblage de l'embase 3 a la tige 2, comme illustré sur la figure 3, les faces d'assemblage 4a de la tige 2 et 4b de 1'embase 3 sont confondues avec le plan d'assemblage 4.
Selon l'invention, comme le montrent plus particulièrement les figures 1 à 3, la section transversale du pion tronconique 9 et du puits tronconique 10 est elliptique et cette section est orientée de manière que son grand axe 12, visible sur les figures 1 et 2 soit contenu dans le plan défini par l'axe longitudinal 2c de la tige 2 et celui 3'a du doigt tronconique de l'embase 3 destinée a recevoir la sphère 8.
La forme tronconique du pion 9 et du puits 10 assure la liaison axiale, par coincement conique, de l'embase 3 et de la tige 2 et la section transversale elliptique de ce pion 9 et de ce puits 10 assurent l'immobilisation en rotation de l'embase 3 par rapport a la tige 2.
En outre, le pion 9 de la tige et le doigt tronconique 3a de l'embase 3 comportent des trous filetés, 13, 14, ménagés respectivement dans les faces en regard de l'embase 3 et de la sphère 8, servant à la préhension et à l'extraction de ces deux éléments.
Pour permettre au praticien d'adapter cette prothèse à la morphologie du patient dans le fémur duquel elle est implantée, il est prévu, comme le montrent les figures 5 a 12, plusieurs types d'embases 3 de formes différentes et se présentant, respectivement, comme normale, sans décalage et sans antéversion, telle qu'illustrée par les figures 5 et 6, comme décalée d'un côté ou de l'autre comme montrée sur les figures 7 et 8 mais sans antéversion, comme antéversée d'un côté, comme montré par les figures 9 et 10 et enfin comme décalée et antéversée d'un côté, comme montré par les figures 11 et 12.
En outre, il est mis à la disposition du praticien un jeu d'au moins quatre sphères 8 de diamètres différents respectivement 22, 26, 28 et 32 mm, ainsi qu'un jeu de dix tiges 2 de dimensions différentes.
De plus, les différentes embases 3 mises à la disposition du praticien peuvent aussi présenter des longueurs de col différentes.
Les embases 3 peuvent être réalisées en tout matériau biocompatible et notamment en acier inoxydable, en chrome cobalt, en alliage titane Ta6v, ayant subi une implantation ionique ou en oxyde métallique, tel que l'alumine ou le zircone.
