Abstract

Hip prosthesis comprises a spherical head with a medullary stem for fixing to the interior of the femur and mounted on the interior of a socket of an ambulatory component comprising a polyethylene or metal cup fixed in a cavity, the surfaces contacting the head and the socket being of high friction material.

Description

La présente invention a pour objet une prothèse totale de hanche. The present invention relates to a total hip prosthesis.

La détérioration de la cavité cotyloïdienne implique fréquemment la mise en place d'une prothèse totale de hanche. Une telle prothèse comprend, d'une part, un élément fémoral présentant une tige médullaire destinée à être fixée à l'os à l'intérieur du fémur, et dont l'extrémité libre est munie d'une tête sphérique et, d'autre part, un élément cotyloïdien destiné à être engagé et fixé dans la cavité cotyloïdienne. L'élément cotyloïdien délimite une cavité sphérique recevant, avec possibilité de pivotement, la tête sphérique de l'élément fémoral. Deterioration of the acetabular cavity frequently involves the installation of a total hip prosthesis. Such a prosthesis comprises, on the one hand, a femoral element having a medullary rod intended to be fixed to the bone inside the femur, and the free end of which is provided with a spherical head and, on the other hand hand, an acetabular element intended to be engaged and fixed in the acetabular cavity. The acetabular element delimits a spherical cavity receiving, with the possibility of pivoting, the spherical head of the femoral element.

Un élément cotyloïdien connu, notamment par le document FR 2 710 836 au nom de la Demanderesse, est constitué par un noyau en matériau favorisant le glissement, le plus souvent en polyéthylène de haute densité, qui délimite la cavité dans laquelle la tête sphérique est montée pivotante. Ce noyau en polyéthylène est inséré dans une cupule métallique fixée dans la cavité cotyloïdienne. L'essentiel des mouvements est obtenu par pivotement de la tête sphérique à l'intérieur du noyau. Cependant, dans certains mouvements de grande amplitude, la cupule en polyéthylène peut également pivoter à l'intérieur de la cupule métallique. II est ainsi possible d'obtenir une double mobilité de la tête sphérique par rapport à la cavité cotyloïdienne. A known acetabular element, in particular from document FR 2 710 836 in the name of the Applicant, consists of a core of material promoting sliding, most often of high density polyethylene, which delimits the cavity in which the spherical head is mounted. swivel. This polyethylene core is inserted into a metal cup fixed in the acetabular cavity. Most of the movements are obtained by pivoting the spherical head inside the core. However, in certain large amplitude movements, the polyethylene cup can also pivot inside the metal cup. It is thus possible to obtain a double mobility of the spherical head relative to the acetabular cavity.

Le but de l'invention est de fournir une prothèse totale de hanche offrant les qualités obtenues à l'aide d'une prothèse à double mobilité, qui limite considérablement les risques de luxation, et qui possède de bonnes capacités de mobilité de la tête sphérique vis-à-vis du noyau, ainsi qu'une longévité importante. The object of the invention is to provide a total hip prosthesis offering the qualities obtained using a dual mobility prosthesis, which considerably limits the risks of dislocation, and which has good mobility capacities of the spherical head. vis-à-vis the core, as well as a significant longevity.

A cet effet, la prothèse qu'elle concerne, du type comprenant une tête sphérique disposée à une extrémité d'une tige médullaire destinée à être fixée à l'os à l'intérieur du fémur, et montée articulée à l'intérieur d'un noyau, lui-même monté articulé à l'intérieur d'un composant acétabulaire constitué par une cupule métallique fixée dans la cavité cotyloïdienne, est caractérisée en ce que les surfaces en contact de la tête et du noyau sont réalisées dans des matériaux à frottement dur. To this end, the prosthesis which it relates to, of the type comprising a spherical head disposed at one end of a medullary rod intended to be fixed to the bone inside the femur, and mounted articulated inside a core, itself mounted articulated inside an acetabular component constituted by a metal cup fixed in the acetabular cavity, is characterized in that the surfaces in contact with the head and the core are made of friction materials hard.

Les surfaces en contact étant réalisées dans des matériaux à frottement dur, leur résistance à l'usure est importante, ce qui permet d'améliorer la longévité de la prothèse. Suivant une caractéristique de l'invention, les matériaux à frottement dur sont choisis parmi les alliages métalliques et les céramiques. Since the contacting surfaces are made of materials with hard friction, their wear resistance is high, which makes it possible to improve the longevity of the prosthesis. According to a characteristic of the invention, the materials with hard friction are chosen from metallic alloys and ceramics.

Dans la mesure où le noyau et la tête sont tous les deux réalisés dans des matériaux à frottement dur, il n'est pas possible d'engager la tête dans le noyau par impaction, dans la mesure où le noyau comporterait alors une déformation irréversible. Dans un tel cas, il est avantageux d'utiliser une tête d'élément fémoral comportant la structure décrite dans le document FR 98 14304 au nom de la Demanderesse. Since the core and the head are both made of hard friction materials, it is not possible to engage the head in the core by impaction, since the core would then have an irreversible deformation. In such a case, it is advantageous to use a femoral element head comprising the structure described in document FR 98 14304 in the name of the Applicant.

Afin d'améliorer encore plus la longévité de la prothèse, en réalisant une répartition des contraintes et une absorption des chocs, le noyau est monté dans le composant acétabulaire avec possibilité de déformation élastique. In order to further improve the longevity of the prosthesis, by achieving stress distribution and shock absorption, the core is mounted in the acetabular component with the possibility of elastic deformation.

Suivant une première forme d'exécution, un insert en matière synthétique, déformable élastiquement, est interposé entre le noyau et le composant acétabulaire, cet insert étant, par exemple, réalisé en polyéthylène. According to a first embodiment, an insert of synthetic material, elastically deformable, is interposed between the core and the acetabular component, this insert being, for example, made of polyethylene.

Selon une première possibilité, l'insert en matière synthétique est fixé sur le noyau et monté articulé dans le composant acétabulaire. Suivant une autre possiblité, l'insert en matière synthétique est fixé dans le composant acétabulaire, et le noyau est monté articulé dans l'insert. According to a first possibility, the plastic insert is fixed to the core and mounted articulated in the acetabular component. According to another possibility, the plastic insert is fixed in the acetabular component, and the core is mounted articulated in the insert.

II doit être remarqué que les mouvements de l'insert vis-à-vis du composant acétabulaire dans le premier cas, et vis-à-vis du noyau dans le deuxième cas, sont de faible amplitude, de telle sorte que les risques d'usure de l'insert en matière synthétique sont extrêmement limités. It should be noted that the movements of the insert with respect to the acetabular component in the first case, and with respect to the core in the second case, are of small amplitude, so that the risks of wear of the plastic insert are extremely limited.

Suivant une autre forme d'exécution de cette prothèse, le composant acétabulaire est déformable élastiquement. According to another embodiment of this prosthesis, the acetabular component is elastically deformable.

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'exemples non limitatifs, plusieurs formes d'exécution de cette prothèse Figures 1 et 2 sont deux vues, respectivement en perspective éclatée et en position assemblée, des différents éléments constitutifs de cette prothèse ; Figures 3 et 5 représentent deux autres formes d'exécution de cette prothèse dans des vues correspondant à la figure 1 ; Figures 4 et 6 correspondent, pour leur part, à une vue conforme à la figure 2, dans le cas de ces deux autres formes d'exécution. In any case, the invention will be clearly understood with the aid of the description which follows, with reference to the appended schematic drawing showing, by way of nonlimiting examples, several embodiments of this prosthesis Figures 1 and 2 are two views, respectively in exploded perspective and in the assembled position, of the various constituent elements of this prosthesis; Figures 3 and 5 show two other embodiments of this prosthesis in views corresponding to Figure 1; Figures 4 and 6 correspond, for their part, to a view according to Figure 2, in the case of these two other embodiments.

La figure 1 représente une prothèse totale de hanche comprenant un composant acétabulaire 2 constitué par une cupule métallique destinée à être fixée dans la cavité cotyloïdienne. Cette prothèse comprend également un noyau métallique ou céramique 3, comportant une cavité interne dans laquelle est destinée à être engagée une tête métallique ou céramique 4. La tête 4 comporte sur une partie de sa surface une zone 5 de retrait de matière permettant son introduction dans le noyau 3 sans réaliser d'impaction. Dans la forme d'exécution représentée aux figures 1 et 2, un insert 6 en matériau synthétique déformable élastiquement, tel que du polyéthylène, est fixé dans la cupule métallique 2. Cet insert élastique 6 possède une surface intérieure 7 de même courbure que la surface extérieure du noyau 3. Ainsi, en conditions d'utilisation de la prothèse, la tête 4 peut pivoter à l'intérieur du noyau 3 et, en cas de mouvements de grande amplitude, le noyau 3 peut pivoter à l'intérieur de l'insert élastique 6. FIG. 1 represents a total hip prosthesis comprising an acetabular component 2 constituted by a metal cup intended to be fixed in the acetabular cavity. This prosthesis also comprises a metallic or ceramic core 3, comprising an internal cavity in which is intended to be engaged a metallic or ceramic head 4. The head 4 has on a part of its surface a zone 5 of material withdrawal allowing its introduction into core 3 without making an impact. In the embodiment shown in Figures 1 and 2, an insert 6 of elastically deformable synthetic material, such as polyethylene, is fixed in the metal cup 2. This elastic insert 6 has an inner surface 7 of the same curvature as the surface outside of the core 3. Thus, under conditions of use of the prosthesis, the head 4 can pivot inside the core 3 and, in the event of large amplitude movements, the core 3 can pivot inside the elastic insert 6.

Les figures 3 et 4 représentent une seconde forme d'exécution de cette prothèse, dans laquelle les mêmes éléments sont désignés par les mêmes références que précédemment. Dans ce second cas, l'insert 6 en matière synthétique est fixé sur le noyau 3, et est mobile, par sa surface extérieure contre la surface intérieure 8 de la cupule 2. Figures 3 and 4 show a second embodiment of this prosthesis, in which the same elements are designated by the same references as above. In this second case, the insert 6 of synthetic material is fixed to the core 3, and is mobile, by its outer surface against the inner surface 8 of the cup 2.

Dans la forme d'exécution représentée aux figures 5 et 6, les mêmes éléments sont désignés par les mêmes références que précédemment. Dans ce cas, l'élasticité de la prothèse est obtenue par une conformation adaptée du composant acétabulaire qui peut, par exemple, bénéficier d'amincissements locaux de matière pour lui conférer la souplesse requise. Le composant acétabulaire 2 peut être aussi réalisé en polyéthylène. In the embodiment shown in Figures 5 and 6, the same elements are designated by the same references as above. In this case, the elasticity of the prosthesis is obtained by an adapted conformation of the acetabular component which can, for example, benefit from local thinning of material to give it the required flexibility. The acetabular component 2 can also be made of polyethylene.

Comme il ressort de ce qui précède, l'invention apporte une grande amélioration à la technique existante, en fournissant une prothèse totale de hanche qui est d'un grand confort pour l'utilisateur, qui évite les risques de luxation, et qui possède une durée de vie élevée. As is apparent from the above, the invention brings a great improvement to the existing technique, by providing a total hip prosthesis which is very comfortable for the user, which avoids the risks of dislocation, and which has a long service life.

Comme il va de soi, l'invention ne se limite pas aux seules formes d'exécution de cette prothèse, décrites ci-dessus à titre d'exemples, elle en embrasse au contraire toutes les variantes. C'est ainsi notamment que la tête 4 pourrait être fixée dans le noyau par d'autres moyens que ceux indiqués et, par exemple, par un jonc rapporté, sans que l'on sorte pour autant du cadre de l'invention.As it goes without saying, the invention is not limited to the sole embodiments of this prosthesis, described above by way of examples, on the contrary it embraces all variants. Thus in particular that the head 4 could be fixed in the core by other means than those indicated and, for example, by an attached rod, without departing from the scope of the invention.
