Abstract
Description
Tige fémorale auto-blocante. Self-locking femoral stem.
L'invention concerne les prothèses de hanche devant être fixées avec ou sans ciment. The invention relates to hip prostheses to be fixed with or without cement.
D'une manière connue, la tige fémorale destinée à être fixée dans le canal médullaire du fémur, présente un col latéralisé agencé pour recevoir directement ou d'une manière rapportée, une tête sphérique. Cette tête est destinée à coopérer, soit directement avec la cavité cotyloïde de l'os illiaque, soit avec un implant cotyloidien présentant un anneau et un noyau. In a known manner, the femoral stem intended to be fixed in the medullary canal of the femur, has a lateralized neck arranged to receive directly or in a reported manner, a spherical head. This head is intended to cooperate, either directly with the acetabular cavity of the iliac bone, or with an acetabular implant having a ring and a nucleus.
Selon l'invention, on a voulu améliorer la fixation de la tige fémorale au niveau notamment, de la partie métaphysaire, étant donné que c'est à ce niveau que la fixation doit être la plus parfaite possible. According to the invention, we wanted to improve the fixation of the femoral stem in particular at the level of the metaphyseal part, since it is at this level that the fixation must be as perfect as possible.
Le problème que se propose de résoudre l'invention est de réaliser une tige fémorale dont la forme est déterminée pour s'adapter parfaitement aux corticales interne et externe pour venir se bloquer dans la zone métaphysaire de l'os. The problem which the invention proposes to solve is to produce a femoral stem whose shape is determined to adapt perfectly to the internal and external cortices in order to become blocked in the metaphyseal zone of the bone.
Un tel problème est résolu en ce que la tige présente dans sa partie proximale, un évidement périphérique conformé pour assurer le dépôt d'une couche de titane poreux sous forme de plasma spray, de manière à ce- que ladite couche ne déborde pas de l'épaisseur de 11 ensemble de la tige, pour former une continuité depuis ladite partie proximale jusqu'à l'extrémité distale. Such a problem is solved in that the rod has in its proximal part, a peripheral recess shaped to ensure the deposition of a layer of porous titanium in the form of plasma spray, so that said layer does not overflow from the thickness of the entire rod, to form a continuity from said proximal part to the distal end.
Il en résulte une bonne adhérence du revêtement poreux sur le substrat. La porosité, de l'ordre de 30 à 40 %, et les anfractuosités, dont les dimensions sont de l'ordre de 200 microns, sont particulièrement bien adaptées pour faciliter la réhabilitation osseuse. This results in good adhesion of the porous coating to the substrate. The porosity, of the order of 30 to 40%, and the crevices, the dimensions of which are of the order of 200 microns, are particularly well suited to facilitate bone rehabilitation.
A noter, que l'on a déjà proposé de déposer sur des tiges fémorales, une couche de titane par plasma spray. Note, that it has already been proposed to deposit on femoral stems, a layer of titanium by plasma spray.
Cependant, dans les techniques connues, cette couche apparait en surépaisseur, de sorte qu'après le passage des rapes pour la préparation du canal médullaire en vue de l'impaction de la tige, l'opérateur a tendance à forcer le passage fait initialement par la rape. Il en résulte des problèmes au niveau de la stabilité dans le temps de la tige.However, in known techniques, this layer appears in excess thickness, so that after the passage of the rapes for the preparation of the medullary canal for the impaction of the rod, the operator tends to force the passage made initially by rape. This results in problems with the stability over time of the rod.
Un autre problème que se propose de résoudre l'invention est d'assurer un remplissage trochantérien pour obtenir un blocage immédiat et éviter tout risque de rotation. Another problem which the invention proposes to solve is to ensure trochanteric filling in order to obtain immediate blocking and to avoid any risk of rotation.
Un tel problème est résolu en ce que la tige présente une section transversale de forme sensiblement triangulaire à bords arrondis, adaptée au canal médullaire et de section progressive depuis la partie distale jusqu'à la partie proximale, tant dans le plan sagittal que dans le plan frontal. Such a problem is solved in that the rod has a cross section of substantially triangular shape with rounded edges, adapted to the medullary canal and of progressive section from the distal part to the proximal part, both in the sagittal plane and in the plane frontal.
Suivant une autre caractéristique, la tige présente, dans le plan frontal et dans sa partie proximale, un ou des plateaux de répartition de contraintes. According to another characteristic, the rod has, in the frontal plane and in its proximal part, one or more stress distribution plates.
L'invention est exposée ci-après plus en détail à l'aide des dessins annexés, dans lesquels
La figure 1 est une vue, dans le plan frontal, de la tige fémorale selon l'invention, avant dépôt de la couche de titane poreux sous forme de plasma spray.The invention is set out below in more detail with the aid of the appended drawings, in which
FIG. 1 is a view, in the frontal plane, of the femoral stem according to the invention, before deposition of the layer of porous titanium in the form of spray plasma.
La figure 2 est une vue semblable à la figure 1 après dépôt de la couche de titane poreux, et impaction de cette dernière dans le canal médullaire. Figure 2 is a view similar to Figure 1 after deposition of the porous titanium layer, and impaction of the latter in the medullary canal.
La figure 3 est une vue de la tige dans le plan sagittal. Figure 3 is a view of the rod in the sagittal plane.
La figure 4 est à grande échelle, une vue partielle en coupe montrant le dépôt de la couche de titane poreux. Figure 4 is a large scale, a partial sectional view showing the deposition of the porous titanium layer.
La figure 5 est une vue en coupe transversale de la tige après son impaction dans le canal médullaire. Figure 5 is a cross-sectional view of the rod after its impaction in the medullary canal.
La figure 6 est une vue, dans le plan frontal, de la tige dans le cas où sa partie proximale présente des plateaux de répartition de contraintes. Figure 6 is a view, in the front plane, of the rod in the case where its proximal part has stress distribution plates.
La tige désignée dans son ensemble par (1), présente dans sa partie proximale, un évidemment périphérique (la) (figure 1). Cet évidemment (la) est destiné à recevoir une couche de titane poreux (2), sous forme de plasma spray (figure 2). The rod designated as a whole by (1), has in its proximal part, an obviously peripheral (la) (Figure 1). This obviously (la) is intended to receive a layer of porous titanium (2), in the form of plasma spray (Figure 2).
De manière particulièrement importante, il apparait qu'après dépôt de la couche de titane poreux (2) dans l'évidemment (la), cette dernière ne déborde pas de l'épaisseur de l'ensemble de la tige, mais se trouve intégrée dans celle-ci, pour former une continuité depuis la partie proximale jusqu a l'extrémité distale de la tige (figure 4). Il apparait donc que les dimensions de la tige fémorale correspondent parfaitement à celles de la dernière râpe volumétrique utilisée pour son impaction. In a particularly important way, it appears that after deposition of the porous titanium layer (2) in the recess (la), the latter does not extend beyond the thickness of the entire rod, but is integrated in this, to form a continuity from the proximal part to the distal end of the rod (Figure 4). It therefore appears that the dimensions of the femoral stem correspond perfectly to those of the last volumetric rasp used for its impaction.
En outre, le dépôt de la couche de titane poreux (2) assure une stabilité définitive, la tige (i) venant par ailleurs se bloquer dans la zone métaphysaire de l'os. In addition, the deposition of the porous titanium layer (2) ensures final stability, the rod (i) also coming to block in the metaphyseal zone of the bone.
A noter que l'implantation de la tige s'effectue de manière à respecter au maximum le capital spongieux, à l'origine de la réhabilitation du plasma spray. Note that the implantation of the rod is carried out in such a way as to respect the spongy capital as much as possible, at the origin of the rehabilitation of the plasma spray.
Suivant une autre caractéristique, la tige (i) présente une section transversale (lb) de forme sensiblement triangulaire à bords arrondis, et adaptée au canal médullaire (figure 5). De même, la section (lb) de la tige est progressive depuis la partie distale jusqu'à la partie proximale, aussi bien dans le plan frontal que dans le plan sagittal. Il en résulte un très bon remplissage trochantérien assurant un blocage sûr et efficace de la tige en supprimant tout effet de rotation. According to another characteristic, the rod (i) has a cross section (lb) of substantially triangular shape with rounded edges, and adapted to the medullary canal (FIG. 5). Similarly, the section (lb) of the rod is progressive from the distal part to the proximal part, both in the frontal plane and in the sagittal plane. This results in a very good trochanteric filling ensuring safe and effective blocking of the rod while eliminating any effect of rotation.
Pour assurer une meilleure répartition des contraintes, la tige peut présenter dans sa partie proximale, un ou des plateaux (lc) (figure 6). Dans le cas de plusieurs plateaux (il) , ces derniers sont disposés d'une manière étagée à la façon d'écailles. To ensure a better distribution of the stresses, the rod may present in its proximal part, one or more plates (lc) (Figure 6). In the case of several plates (II), these are arranged in a stepped manner in the manner of scales.
Les avantages ressortent bien de la description, en particulier on souligne et on rappelle, le remplissage métaphysaire assurant un ancrage solide et une stabilité immédiate. The advantages emerge clearly from the description, in particular it underlines and is recalled, the metaphyseal filling ensuring a solid anchoring and immediate stability.
