Description

Implant Pour le remplacement partiel ou total d'organes de préférence cartilagineux ou osseux Implant For the partial or total replacement of cartilage or bone preferably bodies
La présente invention concerne un implant destiné au remplacement partiel ou total d'organes de préférence cartilagineux ou osseux. The present invention relates to an implant for partial or total replacement of preferably cartilage or bone bodies.

Les implants et plus particulièrement les prothèses d'articulation de genou ou de hanche sont connus. The implants and especially the knee or hip joint prostheses are known. Des améliorations dans le dessin des implants permettent aujourd'hui une mise en oeuvre aisée et rapide de ce type d'articulation. Improvements in implant design now allow an implementation easy and fast for this type of joint. On constate cependant encore un grand nombre de problèmes non résolus. There is, however still many unsolved problems. Ainsi, ces prothèses articulaires ont un taux d'usure extrêmement rapide exigeant leur renouvellement généralement tous les quatre à cinq ans. Thus, these prosthetic joints are an extremely fast rate of wear requiring their renewal usually every four to five years. Pour résoudre ce problème, les fabricants de prothèse s'orientent vers l'utilisation de matériaux de plus en plus durs et de plus en plus résistants alors que les articulations naturelles sont composées de matériaux souples/durs permettant de reprendre les inégalités de formes au cours des mouvements d'articulation. To resolve this issue, prosthesis manufacturers are moving towards the use of more and more hard and more durable materials while the natural joints are made of soft / hard materials to resume inequality forms over articulation movements.

Le but de la présente invention est donc de proposer un implant susceptible de réduire les compressions unitaires articulaires ou autres et les chocs en les redistribuant sur de plus grandes surfaces portantes. The purpose of the present invention to provide an implant may reduce joint or other unit cuts and shocks by redistributing over larger bearing surfaces.

Un autre but de l'invention est de proposer un implant susceptible de réduire la sollicitation mécanique interne d'un organe, c'est-à-dire de réduire les déformations et contraintes de compression qui sont provoquées par l'action d'une charge qui comprime l'organe en le déformant. Another object of the invention is to provide an implant may reduce the inner mechanical stress of an organ, that is to say to reduce the deformation and compressive stresses which are caused by the action of a load compressing the body by deforming it.

L'invention concerne à cet effet un implant pour le remplacement partiel ou total d'organes de préférence cartilagineux ou osseux tels qu'un élément d'articulation, une vertèbre, un os, une portion d'os, etc en vue d'amortir les chocs et diminuer la compression de l'organe traité et/ou des organes adjacents, caractérisé en ce qu'il présente au moins une portion réalisée en un matériau élastiquement déformable et comporte une cavité. Provided for this purpose an implant for partial or total replacement of cartilage or bone preferably of members such as a hinge member, a vertebra, a bone, a bone portion, etc. to cushion shock and reduce the compression of the treated organ and / or of adjacent organs, characterized in that it has at least one portion made of an elastically deformable material and has a cavity.

Selon une forme de réalisation préférée de l'invention, la cavité est fermée. According to a preferred embodiment of the invention, the cavity is closed.

D'autres caractéristiques et avantages de l'invention apparaîtront encore à la lecture de la description qui suit et des dessins joints dans lesquels Other features and advantages of the invention will become apparent from reading the following description and drawings in which
La figure 1 représente une vue partielle en coupe d'une Figure 1 shows a partial sectional view of a
prothèse d'articulation de genou, avec une cavité A knee joint prosthesis, with a cavity

la figure 2 représente une vue partielle en coupe d'une Figure 2 shows a partial sectional view of a
prothèse d'articulation de genou avec une cavité A knee joint prosthesis with a cavity
ouverte de l'implant. open the implant.

L'implant, objet de l'invention, est plus particulièrement destiné au remplacement partiel ou total d'organes osseux en particulier des éléments cartilagineux d'articulation de genou, de hanche, ou de toute autre partie du corps, des vertèbres, des os ou des portions d'os. The implant, subject of the invention is more particularly intended for partial or total replacement of bone bodies in particular cartilaginous components of knee joint, hip, or any other part of the body of the vertebrae, bones or bone portions. Cet implant recouvre donc un grand nombre de formes, telles que plaque, cale, rotule, anneau fermé ou ouvert ou élément constitutif de prothèse existante ou non. The implant therefore covers a large number of shapes, such as plate, wedge, ball, open or closed ring or element of existing denture or not.

Cet implant qui peut donc être de forme quelconque se caractérise d'une part par son enveloppe externe ou surface qui comporte au moins une partie 8 réalisée en un matériau élastique et déformable tel qu'une matière plastique, d'autre part par une cavité 7 fermée ou ouverte disposée à l'intérieur de l'implant. This implant can thus be of any form is characterized on the one hand by its external envelope or surface that has at least one portion 8 made of an elastic and deformable material such as plastic, secondly by a cavity 7 closed or open disposed within the implant.

Cette cavité, de positionnement et de dimension variables en fonction du résultat désiré, coopère avec la surface élastiquement déformable de l'implant et permet d'amortir des chocs générés par les mouvements des organes notamment dans le cas d'une articulation et de mieux répartir la charge sur une plus grande surface notamment au niveau de l'interface implant/os ou implant souple/implant dur. This cavity, positioning and variable dimension according to the desired result, cooperating with the elastically deformable surface of the implant and serves to damp shocks generated by the organs of movement particularly in the case of a joint and better distribute the load over a larger area especially at the implant / bone interface or flexible implant / implant hard. Ainsi, dans l'exemple représenté à la figure 1 qui montre une vue partielle en coupe d'une articulation de genou, l'interface à considérer est désignée par 1 et constitue la liaison plateau tibial ou plaque de base 2 avec l'insert articulaire tibial 3. Thus, in the example shown in Figure 1 which shows a partial sectional view of a knee joint, the interface to be considered is designated 1 and constitutes the tibial plateau bond or base plate 2 with the articular insert tibial 3.

Dans ce cas, on observe une répartition homogène des forces de compression articulaires à la surface du plateau tibial 2. In this case, there is a homogeneous distribution of the joint compressive forces on the surface of the tibial plateau 2.

Dans l'exemple représenté à la figure 2, la cavité 7 de l'implant est au contraire ouverte ce qui permet d'emmancher ledit implant sur l'extrémité d'un os et de le maintenir en contact de pression avec les parois de l'os au moyen d d'un organe de fermeture tel qu'un collier de serrage 10. Cette configuration plus simple et donc plus facile à fabriquer de l'implant permet en outre de jouer sur les épaisseurs de l'enveloppe de l'implant de manière à créer des zones de résistance plus faibles à la déformation en particulier dans les endroits où l'implant est soumis à des sollicitations mécaniques extrêmement fortes. In the example shown in Figure 2, the cavity 7 of the implant is at the open opposite thereby emmancher said implant to the end of a bone and to keep it in pressing contact with the walls of the bone by means of a closure member such as a clamp 10. This simpler configuration and therefore easier to manufacture of the implant also allows to play on the thicknesses of the implant shell so as to create lower areas of resistance to deformation particularly in places where the implant is subjected to extremely high mechanical loads.

En outre, cette cavité peut jouer d'autres rôles. In addition, this recess may play other roles. Elle peut ainsi, dans le cas où elle est poreuse, permettre la diffusion d'un liquide contenu à l'intérieur de la cavité. It may thus, in the case where it is porous, allowing the diffusion of a liquid contained within the cavity. Cette solution peut se révéler particulièrement intéressante dans le cas d'une articulation, l'élément liquide étant un élément lubrifiant. This solution can be particularly interesting in the case of a joint, the liquid element is a lubricant component.

Il est également possible de compartimenter cette cavité de manière à obtenir une répartition plus précise des pressions modifiant le rôle de l'implant. It is also possible to compartmentalize the cavity so as to get a more accurate distribution of pressure changing the role of the implant.

Au contraire, il est possible de mettre la cavité sous pression de manière à venir s'opposer à la pression par exemple articulaire exercée. Rather, it is possible to put the cavity under pressure to come to oppose the pressure exerted by articular example. Ainsi, dans le genou, la pression articulaire varie entre 19,3 kg/cm2 et 2,8 kg/cm2 selon l'appui monopodal du membre en charge. Thus, in the knee joint pressure ranges from 19.3 kg / cm2 and 2.8 kg / cm2 according to OLB-load member.

Dans toute solution retenue indépendamment de la forme d'implant, on conservera toujours le même objectif à savoir, augmenter la surface portante de l'implant puisque il est impossible d'agir sur l'autre facteur important dans ce type de problème à savoir, la diminution de charge. In any solution chosen regardless of the shape of implant, you will always have the same objective ie increase the bearing surface of the implant since it is impossible to act on the other important factor in this type of problem ie, load reduction.

Dans l'exemple représenté à la figure 1, l'implant constitue au moins l'un des éléments constitutifs d'une articulation de genou. In the example shown in Figure 1, the implant comprises at least one of the components of a knee joint. Cette articulation comprend un plateau tibial 2 de préférence métallique maintenu dans le tibia, un insert articulaire tibial 3, un implant fémoral 4 formé ou non d'une seule pièce avec le plateau fémoral 5. L'implant caractéristique de cette articulation est l'insert articulaire tibial 3 qui est constitué d'une base creuse dont l'une des faces est munie d'une encoche (non représentée) destinée à coopérer avec des rainures du plateau tibial 2 de préférence en métal et dont l'autre face présente un élément saillant 6 reproduisant l'espace interglénoïdien du tibia.Dans ce cas, l'ensemble de l'insert 3 à savoir, l'espace interglénoïdien médian non articulaire et les cavités glénoïdes qui sont normalement encroûtées de cartilage et articulaires avec les condyles fémoraux par l'intermédiaire des ménisques intraarticulaires, est en un matériau élastiquement déformable. This hinge comprises a tibial tray 2 preferably made of metal held in the tibia, a tibia joint insert 3, a femoral implant 4 formed or not in one piece with the tray 5. The femoral implant feature of this joint is the insert tibial joint 3 which is constituted by a hollow base whose one side is provided with a notch (not shown) intended to cooperate with the grooves of the tibial tray 2 preferably made of metal and the other face has an element 6 projecting reproducing interglénoïdien space tibia.Dans this case, the entire insert 3 namely, non-articular median interglénoïdien space and the glenoid cavities which are normally encrusted with cartilage and joint with the femoral condyles by means of the intraarticular menisci, is an elastically deformable material. On notera que la pièce 4 constitutive de l'implant fémoral présente également les caractéristiques d'un implant conforme à l'invention puisqu'elle possède une cavité et est réalisée en un matériau élastiquement déformable. Note that the four component part of the femoral implant also has the characteristics of an implant according to the invention since it has a cavity and is made of an elastically deformable material.

On peut bien sûr imaginer que cet implant soit utilisé dans toute autre prothèse articulaire, que ce soit une prothèse de hanche, de coude, etc... On préfèrera souvent que l'élément de la prothèse présentant les caractéristiques objet de la présente invention soit l'élément femelle de ladite prothèse. One can of course imagine that this implant is used in any other joint prosthesis, either a hip replacement, elbow, etc ... We often prefer the element of the prosthesis having the characteristics object of the present invention is the female element of said prosthesis.

Dans ce cas, l'implant aura surtout pour fonction de diminuer les contraintes de compression des organes adjacents à l'organe remplacé. In this case, the implant will function primarily to reduce the compressive stress of adjacent organs to organ replaced.

Cet implant pourra également être utilisé pour remplacer une vertèbre ou être incorporé à l'intérieur d'un os de manière à diminuer les contraintes de compression de l'organe ainsi transformé. The implant can also be used to replace a vertebra or be embedded inside of a bone in order to reduce the compressive stress of the thus transformed body.

Les matériaux élastiquement déformables utilisés pour la fabrication de l'implant devront être biocompatibles. The elastically deformable materials used to manufacture the implant must be biocompatible. A titre d'exemple on peut d'ores et déjà citer un matériau tel que le polyéthylène. For example already can already include a material such as polyethylene.

Ces matériaux permettent la mise en oeuvre de procédés de fabrication plus simples et moins coûteux que l'usinage. These materials allow the implementation of simpler manufacturing process and less expensive than machining.

On peut également imaginer de fabriquer un implant dit bimatière où une partie sera réalisée en un matériau élastiquement déformable, le reste étant réalisé en un matériau rigide métallique ou non. It is also conceivable to manufacture an implant where said bi-material part is made of an elastically deformable material, the remainder being made of a rigid metallic material or not.

Bien évidemment, l'implant peut posséder toute autre forme que celle représentée à la figure unique en fonction de sa destination. Of course, the implant can have any shape other than that shown in the single figure depending on the destination.
