Abstract

The stem has, in its proximal part, an anterior curvature (1c) in the sagittal plane and, in the frontal plane, an inner curvature (1a) corresponding to the so-called "champagne glass" family of extra-curved femurs.

Description

Tige fémorale pour Prothèse de hanche. Femoral stem for hip prosthesis.

L'invention concerne le domaine technique des implants orthopédiques et plus particulièrement des prothèses de hanches. The invention relates to the technical field of orthopedic implants and more particularly hip prostheses.

De nombreuses solutions ont été proposées pour tenter d'obtenir une fixation métaphysaire la plus sûre et la plus efficace possible, étant donné que c'est à ce niveau que la fixation de la tige fémorale doit être particulièrement bien adaptée. Many solutions have been proposed in an attempt to obtain the safest and most effective metaphyseal fixation possible, since it is at this level that the fixation of the femoral stem must be particularly well suited.

On a également proposé des solutions pour tenir compte du fait qu'il existe en réalité, deux grandes familles de fémur, à savoir les fémurs sensiblement rectiligines ou droits et les fémurs courbes, c'est-àdire à large courbure interne. Solutions have also been proposed to take account of the fact that there are in reality two large families of femur, namely the substantially straight or straight femurs and the curved femurs, that is to say with large internal curvature.

La demande de brevet EP 91420329.4 dont le demandeur de la présente est également titulaire définit un ensemble prothétique de la hanche, comprenant deux familles de tiges fémorales, correspondant chacune aux fémurs droits, sensiblement rectilignes et aux fémurs courbes. Patent application EP 91420329.4, of which the applicant of the present also holds a hip prosthetic assembly, comprising two families of femoral rods, each corresponding to straight, substantially rectilinear femurs and to curved femurs.

Les tiges fémorales de chacune des familles, présentent au niveau de leur partie proximale, d'une part, dans le plan sagittal, une courbure antérieure et, d'autre part, dans le plan frontal, une courbure interne.The femoral stems of each of the families have, at their proximal part, on the one hand, in the sagittal plane, an anterior curvature and, on the other hand, in the frontal plane, an internal curvature.

De telles caractéristiques s'avèrent particulièrement importantes et efficaces, pour les fémurs droits et courbes, correspondant généralement respectivement à des sujets agés et jeunes. Par contre, cette solution n'aborde pas le problème de tenir compte des fémurs extracourbe que l'on rencontre très généralement chez de très jeunes sujets. Such characteristics prove to be particularly important and effective, for straight and curved femurs, generally corresponding respectively to elderly and young subjects. On the other hand, this solution does not tackle the problem of taking into account the extra-curved femurs which one very generally meets at very young subjects.

Pour résoudre un tel problème, il a été conçu et mis au point, une tige fémorale qui présente, au niveau de sa partie proximale, une courbure antérieure dans le plan sagittal et, dans le plan frontal, une courbure interne correspondant à la famille des fémurs extra-courbes dits "flute de champagne", selon la classification de NOBLE. To solve such a problem, it was designed and developed, a femoral stem which has, at its proximal part, an anterior curvature in the sagittal plane and, in the frontal plane, an internal curvature corresponding to the family of extra-curved femurs called "champagne flute", according to the NOBLE classification.

Pour tenir compte de cette forme particulière, qui apparait essentiellement au niveau de la métaphyse, la tige fémorale selon l'invention présente, du côté externe, une partie renflée apte à exercer une force de compression au niveau de la corticale externe du fémur, permettant ainsi d'équilibrer l'évasement généré par la forte courbure interne. To take account of this particular shape, which appears essentially at the level of the metaphysis, the femoral stem according to the invention has, on the external side, a bulged part capable of exerting a compressive force at the level of the external cortex of the femur, allowing thus balancing the flaring generated by the strong internal curvature.

Toujours en ayant pour objectif de tenir compte de la morphologie du fémur, la tige présente un col qui est décalé angulairement dans le plan sagittal par rapport à l'axe de symétrie, pour correspondre à l'angle d'antéversion de la tête du fémur. Still having the objective of taking into account the morphology of the femur, the stem has a neck which is angularly offset in the sagittal plane relative to the axis of symmetry, to correspond to the anteversion angle of the head of the femur .

Le col est latéralisé en fonction du rayon de courbure interne, pour correspondre à l'angle cervico-diaphysaire souhaité. The neck is lateralized according to the internal radius of curvature, to correspond to the desired cervico-diaphyseal angle.

A noter également qu'en fonction de l'augmentation de la taille, la longueur du col est augmentée selon la direction de l'angle cervico-diaphysaire. Note also that depending on the increase in size, the length of the neck is increased according to the direction of the cervico-diaphyseal angle.

L'invention est exposée, ci-après plus en détail à l'aide des dessins annexés, dans lesquels:
La figure 1 est une vue de face d'une tige fémorale selon l'invention; I on a superposé une tige fémorale de même taille, correspondant à un fémur courbe (tracé traits mixtes) et à un fémur droit (tracé traits interrompus), correspondant à l'enseignement de la demande de brevet EP 91420329.4.The invention is set out below in more detail using the appended drawings, in which:
Figure 1 is a front view of a femoral stem according to the invention; I a femoral rod of the same size has been superimposed, corresponding to a curved femur (line drawn with mixed lines) and to a straight femur (line drawn with broken lines), corresponding to the teaching of patent application EP 91420329.4.

La figure 2 est une vue de profil de la tige fémorale correspondant à la figure 1. FIG. 2 is a side view of the femoral stem corresponding to FIG. 1.

La tige fémorale désignée dans son ensemble par (1) comprend au niveau de sa partie proximale et dans le plan frontal, une courbure interne (la) correspondant à la famille des fémurs extra-courbe, dont la partie métaphysaire a une forme en flûte de champagne. A l'opposé de la courbure (la), c'est-à-dire du côté externe, la tige présente directement lors de sa fabrication, une partie renflée (1 b).Cette partie (i b) a pour but d'exercer une force de compression au niveau de la corticale externe du fémur après introduction de la tige dans le canal médullaire, permettant d'équilibrer l'évasement généré par la forte courbure interne (la)~
On voit donc que la combinaison de la courbure interne (la) et de la partie (lob) assure un remplissage métaphysaire parfait dans le cas d'un fémur extra courbe.The femoral stem generally designated by (1) comprises, at the level of its proximal part and in the frontal plane, an internal curvature (la) corresponding to the family of extra-curved femurs, the metaphyseal part of which has a flute shape of Champagne. Opposite the curvature (la), that is to say on the external side, the rod has directly during its manufacture, a swollen part (1 b). This part (ib) is intended to exert a compression force at the level of the external cortex of the femur after introduction of the rod into the medullary canal, making it possible to balance the flaring generated by the strong internal curvature (la) ~
We therefore see that the combination of the internal curvature (la) and the part (lob) ensures perfect metaphyseal filling in the case of an extra curved femur.

Il apparait que la courbure interne (la) est beaucoup plus accentuée que dans le cas d'une tige fémorale adaptée pour les fémurs courbes (tracé traits mixtes) (figure 1) et encore plus par rapport au fémur droit (tracé traits interrompus) (figure 1). De même, la partie renflée (lob) est en relation dimentionnelle avec l'évasement interne généré par le rayon de courbure (la).  It appears that the internal curvature (la) is much more accentuated than in the case of a femoral stem adapted for curved femurs (tracing mixed lines) (figure 1) and even more compared to the right femur (tracing broken lines) ( figure 1). Likewise, the bulged part (lob) is in dimensional relationship with the internal flaring generated by the radius of curvature (la).

La tige fémorale, telle que définie pour les fémurs extracourbes, présente dans le plan sagittal, une courbure antérieure (il). Ce rayon de courbure antérieur (1c) est le même, aussi bien pour une tige fémorale de la famille des fémurs droits que pour une tige fémorale de la famille des fémurs courbes. On renvoie à la demande de brevet EP 91420329.4.  The femoral stem, as defined for the extra-curved femurs, presents in the sagittal plane, an anterior curvature (II). This anterior radius of curvature (1c) is the same, both for a femoral stem of the family of straight femurs as for a femoral stem of the family of curved femurs. Reference is made to patent application EP 91420329.4.

La tige présente un col (nid) latéralisé dans le plan frontal et qui est décalé en combinaison avec la courbure interne (1 a). Ce décalage correspond à l'angle cervico diaphysaire prothétique. The stem has a neck (nest) lateralized in the frontal plane and which is offset in combination with the internal curvature (1a). This offset corresponds to the prosthetic diaphyseal cervico angle.

En outre, le col présente, dans le plan sagittal, un décalage par rapport à l'axe de symétrie qui correspond à l'antéversion de la tête fémorale. In addition, the neck has, in the sagittal plane, an offset with respect to the axis of symmetry which corresponds to the anteversion of the femoral head.

Bien évidemment, la tige (1), telle que définie selon les caractéristiques de l'invention, est exécutée dans différentes tailles. Obviously, the rod (1), as defined according to the characteristics of the invention, is executed in different sizes.

En fonction de l'augmentation de la taille, la longueur du col (Id) est augmentée selon la direction (xx') de l'angle cervico-diaphysaire. Depending on the increase in size, the length of the neck (Id) is increased in the direction (xx ') of the cervico-diaphyseal angle.

Les avantages ressortent bien de la description.  The advantages are apparent from the description.
