Description

L'invention se rattache au secteur technique des implantsThe invention relates to the technical sector of implants

orthopédiques. Plus particulièrement, l'invention concerne une tige fémorale pour prothèse de hanche.  Orthopedic. More particularly, the invention relates to a femoral stem for hip prosthesis.

D'une manière parfaitement connue pour un homme du métier, une tige fémorale est destinée à être implantée dans le canal médullaire du fémur. Au niveau de sa partie proximale, la tige présente un col, généralement incliné par rapport à l'axe fémoral, et destiné à recevoir une 10 tête fémorale pour coopérer avec un implant cotyloïdien fixé dans la cavité cotyloïdienne de l'os iliaque. Le col fémoral peut faire partie intégrante de la tige fémorale au niveau de sa partie métaphysaire ou bien constituer un élément indépendant en faisant office de col modulaire. Parmi les différentes tiges fémorales destinées à être impactées sans ciment, on 15 distingue essentiellement les tiges anatomiques présentant un profil droit et un profil gauche, d'une part, et les tiges droites ou symétriques, d'autre part.  In a manner perfectly known to a person skilled in the art, a femoral stem is intended to be implanted in the medullary canal of the femur. At its proximal part, the rod has a neck, generally inclined relative to the femoral axis, and intended to receive a femoral head to cooperate with an acetabular implant fixed in the acetabular cavity of the iliac bone. The femoral neck can be an integral part of the femoral stem at the level of its metaphyseal part or else constitute an independent element by acting as a modular neck. Among the various femoral stems intended to be impacted without cement, there is essentially a distinction between anatomical stems having a right profile and a left profile, on the one hand, and straight or symmetrical stems, on the other hand.

L'invention concerne plus particulièrement les tiges sans ciment dites << anatomiques ".  The invention relates more particularly to cementless rods called "anatomical".

Dans une tige droite ou symétrique, l'opérateur cherche un bon calage pour un certain nombre d'appuis bloquants, pour obtenir un effet de coincement métaphyso-diaphysaire. Les pressions physiologiques ne sont toutefois pas respectées.  In a straight or symmetrical rod, the operator seeks a good setting for a certain number of blocking supports, in order to obtain a metaphyso-diaphyseal wedging effect. Physiological pressures are however not respected.

Inversement, dans le cas d'une tige fémorale anatomique, l'opérateur cherche à obtenir une bonne répartition des contraintes entre l'implant et l'os, tout en ayant pour objectif d'obtenir un calage métaphysaire et anatomique suffisant.  Conversely, in the case of an anatomical femoral stem, the operator seeks to obtain a good distribution of the stresses between the implant and the bone, while having the objective of obtaining a sufficient metaphyseal and anatomical setting.

La plupart des tiges fémorales propose une forme de section 5 transversale au niveau métaphysaire qui ne permet pas d'obtenir un calage métaphysaire et anatomique satisfaisant, et d'assurer une bonne répartition des contraintes. En effet, cette section métaphysaire est soit de forme générale elliptique, ce qui ne permet pas un bon calage métaphysaire, soit de section sensiblement quadrangulaire, ce qui ne permet pas d'assurer une 10 bonne répartition des contraintes.  Most femoral stems offer a cross-sectional shape at the metaphyseal level which does not make it possible to obtain a satisfactory metaphyseal and anatomical setting, and to ensure a good distribution of the stresses. In fact, this metaphyseal section is either generally elliptical in shape, which does not allow good metaphyseal setting, or of substantially quadrangular section, which does not allow good stress distribution.

On observe également que, dans le cas d'une tige fémorale anatomique, la partie diaphysaire doit être fine, c'est-à-dire de section transversale réduite et n'intervient pas pour le calage, mais seulement pour 15 le guidage de la tige au moment de sa mise en place.  It is also observed that, in the case of an anatomical femoral stem, the diaphyseal part must be thin, that is to say of reduced cross section and does not intervene for the setting, but only for the guidance of the rod at the time of its installation.

L'invention s'est fixée pour but de remédier à ce.s incorvénienlts, de manière simple, sûre, efficace et rationnelle.  The object of the invention is to remedy this inconvenience in a simple, safe, efficient and rational manner.

Le problème que se propose de résoudre l'invention est de réaliser une tige fémorale du type anatomique conformée pour assurer un bon calage à la fois métaphysaire et anatomique, tout en facilitant son guidage diaphysaire au moment de sa mise en place.  The problem which the invention proposes to solve is to produce a femoral stem of the anatomical type shaped to ensure good timing both metaphyseal and anatomical, while facilitating its diaphyseal guidance when it is put in place.

Pour résoudre un tel problème, il a été conçu et mis au point une tige fémorale anatomique pour prothèse de hanche destinée à être implantée sans ciment dans le canal médullaire du fémur et comprenant un col, une partie métaphysaire et une partie diaphysaire, remarquable en ce que: - la partie métaphysaire, de section transversale sensiblement elliptique, comprend, du côté externe, un méplat formant 2 arêtes angulaires apte à assurer un bon calage métaphysaire et anatomique; - la partie diaphysaire est de section transversale réduite pour ne pas être en contact avec la corticale, ladite section étant équipée d'un élément faisant office de centreur au moment de l'implantation.  To solve such a problem, it was designed and developed an anatomical femoral stem for hip prosthesis intended to be implanted without cement in the medullary canal of the femur and comprising a neck, a metaphyseal part and a diaphyseal part, remarkable in that that: - the metaphyseal part, of substantially elliptical cross-section, comprises, on the external side, a flat forming 2 angular edges capable of ensuring good metaphyseal and anatomical wedging; - The diaphyseal part is of reduced cross section so as not to be in contact with the cortex, said section being equipped with an element acting as a centering device at the time of implantation.

Pour résoudre le problème posé d'éviter tout effet de coincement diaphysaire durant l'utilisation de la prothèse, l'élément faisant office de centreur est réalisé dans un matériau souple et rapidement résorbable, et est constitué par une bague emmanchée à l'extrémité distale de la partie diaphysaire.  To resolve the problem posed of avoiding any diaphyseal jamming effect during the use of the prosthesis, the element acting as a centering device is made of a flexible and rapidly absorbable material, and is constituted by a ring fitted at the distal end. of the diaphyseal part.

Pour résoudre le problème posé de faciliter la mise en place de la tige, la bague a une section tronconique de section dégressive en direction de l'extrémité distale.  To solve the problem posed of facilitating the positioning of the rod, the ring has a tapered section of tapering section in the direction of the distal end.

Pour résoudre le problème posé d'améliorer le respect de la transmission anatomique des contraintes, la partie métaphysaire présente, au niveau du col, une collerette débordant du côté interne.  To resolve the problem posed of improving compliance with the anatomical transmission of stresses, the metaphyseal part has, at the level of the neck, a flange projecting from the internal side.

Pour résoudre le problème posé d'éviter les contacts avec les 25 corticales, l'extrémité distale de la partie diaphysaire est biseautée du côté antérieur.  To resolve the problem of avoiding contact with the cortices, the distal end of the diaphyseal part is bevelled on the anterior side.

Selon une autre caractéristique, la partie métaphysaire reçoit un revêtement macro-poreux pour faciliter la repousse osseuse, tandis que la partie diaphysaire est non revêtue et présente une extrémité distale lisse.  According to another characteristic, the metaphyseal part receives a macro-porous coating to facilitate bone regrowth, while the diaphyseal part is uncoated and has a smooth distal end.

L'invention est exposée ci-après plus en détail à l'aide des figures des dessins annexés dans lesquels: - la figure 1 est une vue en perspective de la tige fémorale selon l'invention après la mise en place de l'élément faisant office de centreur; - la figure 2 est une vue de face de la prothèse après mise en place de 10 l'élément centreur; - la figure 3 est une vue de dessus de la tige fémorale; - la figure 4 est une vue partielle en coupe de l'extrémité distale de la partie diaphysaire montrant le montage de l'élément centreur; Comme indiqué, la tige fémorale, désignée dans son ensemble par (1), est du type anatomique et présente un col fémoral (la), une partie métaphysaire (lb) et une partie diaphysaire ('c). Le col fémoral (la) peut être solidaire directement de la partie métaphysaire (lb) ou être exécuté sous forme d'un élément indépendant pour constituer un col modulaire. 20 Selon l'invention, la partie métaphysaire (lb), de section transversale sensiblement elliptique, comprend, du côté externe, un méplat (lbl) apte à assurer un bon calage métaphysaire et anatomique. Ce méplat (lbl) est orienté angulairement en direction du col fémoral (la). A titre indicatif, 25 nullement limitatif, le méplat (lbl) a un angle de 10 par rapport à l'axe fémoral (X-X'). On renvoie aux figures 1 et 2. Le méplat (lbl) forme deux arêtes angulaires.  The invention is set out below in more detail with the aid of the figures of the appended drawings in which: - Figure 1 is a perspective view of the femoral stem according to the invention after the placement of the element making office of centralizer; FIG. 2 is a front view of the prosthesis after the centering element has been put in place; - Figure 3 is a top view of the femoral stem; - Figure 4 is a partial sectional view of the distal end of the diaphyseal part showing the mounting of the centering element; As indicated, the femoral stem, generally designated by (1), is of the anatomical type and has a femoral neck (la), a metaphyseal part (lb) and a diaphyseal part ('c). The femoral neck (la) can be directly attached to the metaphyseal part (lb) or be executed as an independent element to form a modular neck. According to the invention, the metaphyseal part (1b), of substantially elliptical cross section, comprises, on the external side, a flat (lbl) capable of ensuring good metaphyseal and anatomical wedging. This flat (lbl) is angularly oriented in the direction of the femoral neck (la). By way of indication, which is in no way limitative, the flat part (lbl) has an angle of 10 relative to the femoral axis (X-X '). We refer to Figures 1 and 2. The flat (lbl) forms two angular edges.

La partie métaphysaire (lc) est de section transversale réduite pour ne pas être en contact au moment de l'impaction de l'ensemble de la tige, avec les corticales. Dans ces conditions, pour assurer le guidage de la tige, 5 au moment de sa mise en place, l'extrémité distale de la partie diaphysaire (1 c) est équipée d'un élément (2) faisant office de centreur.  The metaphyseal part (lc) is of reduced cross section so as not to be in contact at the time of the impaction of the entire rod, with the cortices. Under these conditions, in order to guide the rod 5 when it is put in place, the distal end of the diaphyseal part (1 c) is equipped with an element (2) acting as a centering device.

Cet élément (2) est constitué par une bague emmanchée à l'extrémité distale de la partie diaphysaire. La bague est réalisée dans un matériau souple et résorbable, étant donné que la fonction de cette bague de centrage 10 a pour but d'assurer le guidage de la partie diaphysaire au moment de la mise en place de la tige. Par exemple, cette bague (3) est réalisée en acide polyglycolactique ou en gélatine. Avantageusement, la bague (3) a une section tronconique de section dégressive en direction de l'extrémité distale.  This element (2) consists of a ring fitted at the distal end of the diaphyseal part. The ring is made of a flexible and absorbable material, given that the function of this centering ring 10 is to ensure the guidance of the diaphyseal part when the rod is put in place. For example, this ring (3) is made of polyglycolactic acid or gelatin. Advantageously, the ring (3) has a frustoconical section of tapering section in the direction of the distal end.

La partie diaphysaire (lc), notamment au niveau de l'extrémité distale, présente une section transversale sensiblement circulaire. De même, cette extrémité distale est biseautée en (lcl) du côté antérieur, pour éviter tout contact avec les corticales.  The diaphyseal part (lc), in particular at the distal end, has a substantially circular cross section. Likewise, this distal end is bevelled at (lcl) on the anterior side, to avoid contact with the cortices.

Dans une forme de réalisation préférée, la partie métaphysaire (lb) reçoit un revêtement macro-poreux pour faciliter la repousse osseuse. Par exemple, on peut utiliser de la poudre de titane par projection plasma avec de l'hydroxyapathite.  In a preferred embodiment, the metaphyseal part (lb) receives a macro-porous coating to facilitate bone regrowth. For example, titanium powder can be used by plasma spraying with hydroxyapathite.

La partie diaphysaire (lc) est non revêtue, l'extrémité distale étant lisse.  The diaphyseal part (lc) is uncoated, the distal end being smooth.

Dans une forme de réalisation en variante, la partie métaphysaire (lb) présente, au niveau du raccordement avec le col (la), une collerette (ld) débordant du côté interne pour améliorer le respect de la transmission anatomique des contraintes.  In an alternative embodiment, the metaphyseal part (lb) has, at the connection with the neck (la), a flange (ld) projecting from the internal side to improve compliance with the anatomical transmission of stresses.

Les avantages ressortent bien de la description, en particulier on souligne et on rappelle - l'élément centreur antérieur souple est en contact avec la corticale du canal médullaire, afin d'éviter tout contact de la partie diaphysaire de la 10 tige avec les corticales; - le bon calage métaphysaire anatomique obtenu résultant de la formation d'un méplat au niveau métaphysaire; - la bonne répartition des contraintes résultant de la section partiellement elliptique métaphysaire du côté interne.  The advantages emerge clearly from the description, in particular it is emphasized and recalled - the flexible anterior centralizing element is in contact with the cortex of the medullary canal, in order to avoid any contact of the diaphyseal part of the rod with the cortices; - the correct anatomical metaphyseal setting obtained resulting from the formation of a flat at the metaphyseal level; - the good distribution of the stresses resulting from the partially elliptical metaphyseal section on the internal side.
