Abstract
Description
Prothèse totale de genou sans ciment
La présente invention concerne le domaine de la chirurgie, en particulier des prothèses, et a pour objet une prothèse totale de genou sans ciment
Le traitement des gonarthroses à évolution irréversible s'effectue généralement par arthroplastie totale du genou, c'est-à-dire par pose d'une prothèse totale de genou.Cementless total knee replacement
The present invention relates to the field of surgery, in particular prostheses, and relates to a total knee prosthesis without cement.
The treatment of osteoarthritis with irreversible evolution is generally carried out by total knee arthroplasty, that is to say by fitting a total knee prosthesis.
Actuellement, les prothèses totales de genoux sont réalisées au moyen de trois pièces principales, à savoir un bouclier condylien monté sur l'extrémité distale du fémur, un plateau tibial équipant le sommet du tibia et un médaillon rotulien monté sur la face interne de la rotule, ces trois pièces étant en contact entre elles et remplaçant les cartilages de l'articulation détruite. Currently, total knee prostheses are made using three main parts, namely a condylar shield mounted on the distal end of the femur, a tibial plateau equipping the top of the tibia and a patellar medallion mounted on the internal face of the kneecap , these three parts being in contact with each other and replacing the cartilages of the destroyed joint.
Au niveau de leur liaison avec les extrémités ou faces subsistantes des os, les pièces formant les prothèses connues présentent, soit une surface lisse, soit une surface cruantée. Les pièces de prothèses à surface lisse sont fixées aux extrémités ou faces respectives au moyen d'un ciment assurant, lors de l'implantation, le comblement entre l'os et l'implant. At their connection with the ends or remaining faces of the bones, the parts forming the known prostheses have either a smooth surface or a notched surface. The prosthesis parts with smooth surface are fixed to the respective ends or faces by means of a cement ensuring, during the implantation, the filling between the bone and the implant.
Cependant, une prothèse cimentée comporte à terme un risque de descellement aseptique et les difficultés opératoires se présentant en cas de reprises chirurgicales, en particulier l'ablation du ciment, occasionnent de très délicats problèmes techniques.However, a cemented prosthesis eventually involves a risk of aseptic loosening and the operational difficulties that arise in the event of surgical resumptions, in particular the removal of the cement, cause very delicate technical problems.
Pour obvier aux inconvénients des prothèses à surface lisse, il a été proposé des prothèses à surface cruantée, à savoir, par exemple, à couverture madréporique, à couverture en fils de titane ou à surface frittée par projection. La couverture madréporique consiste en un surfaçage micro-et macrobillé permettant une fivxa- tion sans ciment et favorisant une réhabitation osseuse sur la prothèse. De même, un surfaç#age en fils de titane généralement disposés en spires aléatoires comprimées est également destiné à réaliser une réhabitation osseuse. To obviate the drawbacks of prostheses with a smooth surface, prostheses with serrated surface have been proposed, namely, for example, with madreporic cover, with titanium wire cover or with sintered surface by projection. The madreporic cover consists of a micro- and macrobeaded surfacing allowing cementless fivxation and promoting bone rehabitation on the prosthesis. Likewise, a surfacing of titanium wires generally arranged in compressed random turns is also intended to achieve bone rehabitation.
Toutefois, les prothèses de genoux à couverture madréporique ne permettent pas une stabilité immédiate par autoblocage, la stabilisation définitive ne devenant effective qu'après réhabitation osseuse et ossification secondaire. En outre, le revêtement de microet macrobilles présente l'inconvénient d'une relative fragilité de la fixation desdites billes sur leur support, pouvant entraîner leur passage dans l'articulation avec, pour conséquence, une lésion des surfaces prothétiques en contact. However, knee prostheses with madreporic cover do not allow immediate stability by self-locking, definitive stabilization only becoming effective after bone rehabitation and secondary ossification. In addition, the coating of micro and macrobeads has the drawback of a relative fragility in the fixing of said balls on their support, which can cause them to pass through the joint with, as a consequence, damage to the prosthetic surfaces in contact.
Les prothèses de genoux, dont le surfaçage est réalisé en fils de titane disposés en spires aléatoires comprimées, présentent l'inconvénient, du fait de la disposition des spires de manière aléatoire, de ne pas permettre une réhabitation homogène, ce qui peut être préjudiciable à la stabilisation définitive. Knee prostheses, the surfacing of which is made of titanium wires arranged in random compressed turns, have the drawback, due to the arrangement of the turns in a random manner, of not allowing a homogeneous rehabitation, which can be detrimental to definitive stabilization.
De même, les prothèses à surfaçage fritté par projection présentent des ondulations et des irrégularités micrométriques non homogènes ne permettant non plus une réhabitation correcte. Similarly, prostheses with sintered surfacing by projection have non-homogeneous micrometric undulations and irregularities which do not allow correct rehabitation either.
En outre, dans les prothèses connues, le plateau tibial est généralement bloqué sur l'extrémité du tibia au moyen d'une vis. Une telle vis ne permet, cependant, pas d'éviter une rotation éventuelle du plateau tibial après sa pose ou lors de la réhabitation. In addition, in known prostheses, the tibial plateau is generally blocked on the end of the tibia by means of a screw. Such a screw does not, however, prevent a possible rotation of the tibial plateau after its installation or during rehabitation.
Enfin, dans les prothèses connues, la surface d'appui tibiale est toujours une surface unique, de sorte que les risques de pivotement et d'un mouvement de bascule dûs à des efforts de flexion-extension-rotation sont très élevés, entraînant un risque de descellement aseptique, voire d'impossibilité de réhabitation osseuse. Finally, in known prostheses, the tibial bearing surface is always a single surface, so that the risks of pivoting and of a rocking movement due to bending-extension-rotation forces are very high, entailing a risk. aseptic loosening, or even impossibility of bone rehabitation.
La présente invention a pour but de pallier ces inconvénients. The present invention aims to overcome these drawbacks.
Elle a, en effet, pour objet une prothèse totale de genou sans ciment, essentiellement constituée par un bouclier condylien monté sur l'extrémité distale du fémur, par un plateau tibial équipant l'extrémité du tibia et par un médaillon rotulien fixé sur la face interne de la rotule, caractérisée en ce que le bouclier condylien, le plateau tibial et le médaillon rotulien présentent, sur leur face d'application contre les parties correspondantes du fémur, du tibia et de la rotule, un surfaçage en treillis métalliques biocompatibles multicouches géométriquement croisés et comprimés et en ce que le plateau tibial est pourvu d'un élément antirotation. Its purpose is in fact a total cementless knee prosthesis, essentially constituted by a condylar shield mounted on the distal end of the femur, by a tibial plateau equipping the end of the tibia and by a patellar medallion fixed on the face. internal patella, characterized in that the condylar shield, the tibial plateau and the patellar medallion have, on their face of application against the corresponding parts of the femur, tibia and patella, a geometrical biocompatible metallic lattice surfacing crossed and compressed and in that the tibial plateau is provided with an anti-rotation element.
L'invention sera mieux comprise, grâce à la description annexée, qui se rapporte à un mode de réalisation préféré, donné à titre d'exemple non limitatif, et expliqué avec référence aux dessins schématiques annexés, dans lesquels
la figure 1 est une vue éclatée en élévation et en coupe de la prothèse totale de genou conforme à l'invention ;
la figure 2 est une vue en élévation par l'arrière du plateau tibial
la figure 3 est une vue en coupe du bouclier condylien suivant A-A de la figure 1, et
la figure 4 est une vue en plan de la face du médaillon rotulien appliquée sur la rotule.The invention will be better understood from the appended description, which relates to a preferred embodiment, given by way of nonlimiting example, and explained with reference to the appended schematic drawings, in which
Figure 1 is an exploded view in elevation and in section of the total knee prosthesis according to the invention;
Figure 2 is an elevational view from the rear of the tibial plateau
FIG. 3 is a sectional view of the condylar shield along AA of FIG. 1, and
Figure 4 is a plan view of the face of the patellar medallion applied to the patella.
Conformément à l'invention, et comme le montrent, à titre d'exemple, les figure 1 à 4 des dessins annexés, la prothèse totale de genou sans ciment, qui est essentiellement constituée par un bouclier condylien 1 monté sur l'extrémité distale du fémur, par un plateau tibial 2 équipant l'extrémité du tibia et par un médaillon rotulien 3 fixé sur la face interne de la rotule, et caractérisée en ce que le bouclier condylien 1, le plateau tibial 2 et le médaillon rotulien 3 présentent, sur leur face d'application contre les parties correspondantes du fémur, du tibia et de la rotule, un surfaçage 4 en treillis métalliques biocompatibles multicouches géométriquement croisés et comprimés. En outre, le plateau tibial 2 est pourvu d'un élément anti-rotation 5. According to the invention, and as shown, by way of example, FIGS. 1 to 4 of the appended drawings, the total cementless knee prosthesis, which is essentially constituted by a condylar shield 1 mounted on the distal end of the femur, by a tibial plateau 2 equipping the end of the tibia and by a patellar medallion 3 fixed on the internal face of the patella, and characterized in that the condylar shield 1, the tibial plateau 2 and the patellar medallion 3 have, on their application face against the corresponding parts of the femur, the tibia and the patella, a surfacing 4 in biocompatible metallic mesh geometrically crossed and compressed multilayers. In addition, the tibial plateau 2 is provided with an anti-rotation element 5.
Le surfaçage 4 des faces d'application des éléments 1 à 3 est avantageusement constitué par trois couches superposées de treillis métalliques en fils de titane et présente à sa surface des espaces réguliers destinés à la réhabitation, de préférence d'une section 2 de 500 rm . Un tel surfaçage permet une amélioration sensible de la réhabitation osseuse, notamment du fait d'une meilleure homogénéité, et en tout cas une réhabitation très nettement améliorée par rapport à celles obtenues au moyen des surfaçages de prothèses connus à ce jour. The surfacing 4 of the application faces of the elements 1 to 3 is advantageously constituted by three superimposed layers of wire mesh of titanium wires and has on its surface regular spaces intended for rehabitation, preferably of a section 2 of 500 rm . Such surfacing allows a significant improvement in bone rehabitation, in particular due to better homogeneity, and in any case rehabitation very much improved compared to those obtained by means of surfacing prostheses known to date.
L'élément anti-rotation 5 (figures 1 et 2) est avantageusement sous forme d'une lame allongée de section rectangulaire, insérée dans une fente 6 de section correspondante du plateau tibial 2, maintenue par son extrémité libre dans ledit plateau 2 au moyen de deux appendices d'accrochage 7 et bloquée en position de service dans le plateau 2 par le plateau en polyéthylène 8 destiné à coopérer avec la face externe du bouclier condylien 1 et fixé sur le plateau 2 par encliquetage. The anti-rotation element 5 (FIGS. 1 and 2) is advantageously in the form of an elongated blade of rectangular section, inserted into a slot 6 of corresponding section of the tibial plateau 2, held by its free end in said plateau 2 by means two attachment appendages 7 and locked in the service position in the tray 2 by the polyethylene tray 8 intended to cooperate with the external face of the condylar shield 1 and fixed on the tray 2 by snap-fastening.
Cet élément 5 peut présenter des surfaces lisses ou munies d'un surfaçage 4. This element 5 may have smooth surfaces or provided with a surface 4.
De manière connue, le bouclier condylien 1, le plateau tibial 2 et le médaillon rotulien 3 sont munis, en outre, d'ergots ou de tétons 9 de bloquage en position. Conformément à une autre caractéristique de l'invention, ces ergots ou tétons 9 présentent avantageusement une surface lisse et sont munis, à intervalles réguliers, de stries longitudinales 10 (figure 1). Ces stries longitudinales permettent une amélioration du maintien desdits tétons ou ergots 9 dans leur logement correspondant prévu dans les extrémités ou faces correspondantes des os. In known manner, the condylar shield 1, the tibial plateau 2 and the patellar medallion 3 are further provided with lugs or nipples 9 for locking in position. According to another characteristic of the invention, these lugs or pins 9 advantageously have a smooth surface and are provided, at regular intervals, with longitudinal ridges 10 (FIG. 1). These longitudinal striations allow an improvement in the retention of said pins or lugs 9 in their corresponding housing provided in the corresponding ends or faces of the bones.
Selon une autre caractéristique de l'invention, et comme le montrent plus particulièrement les figures 1 et 2 des dessins annexés, le plateau tibial 2 est avantageusement pourvu de parties 11, en saillie sur sa périphérie, présentant un plan incliné 12 sur leur côté tourné vers la face d'appui du plateau et destinées à s'appliquer par lesdits plans inclinés 12 sur des portions coupées de manière correspondante de l'extrémité du tibia à la manière d'une couronne. Grâce à ce mode de réalisation, il est possible de réaliser un encapuchonnage de l'extrémité du tibia au moyen du plateau tibial lors de la mise en place de ce dernier, de sorte que le maintien dudit plateau tibial est encore amélioré et que la réhabitation osseusse et l'ossification secondaire sont accélérées. According to another characteristic of the invention, and as shown more particularly in Figures 1 and 2 of the accompanying drawings, the tibial plateau 2 is advantageously provided with parts 11, projecting on its periphery, having an inclined plane 12 on their turned side towards the bearing face of the plate and intended to be applied by said inclined planes 12 to correspondingly cut portions of the end of the tibia in the manner of a crown. Thanks to this embodiment, it is possible to cover the end of the tibia by means of the tibial plateau when the latter is put in place, so that the maintenance of said tibial plateau is further improved and that rehabitation osseusse and secondary ossification are accelerated.
Grâce à l'invention, il est possible de réaliser une prothèse totale de genou sans ciment permettant une adaptation facilitée sur les extrémités des os et un maintien amélioré, tant au niveau de l'autoblocage immédiat qu'au niveau de la réhabitation osseuse et de l'ossification secondaire. Thanks to the invention, it is possible to produce a total knee prosthesis without cement allowing easier adaptation on the ends of the bones and improved maintenance, both in terms of immediate self-locking and in terms of bone rehabitation and secondary ossification.
Bien entendu, l'invention n'est pas limitée au mode de réalisation décrit et représenté aux dessins annexés. Des modifications restent possibles, notamment du point de vue de la constitution des divers éléments pour par substitution d'équivalents techniques, sans sortir pour autant du domaine de protection de l'invention. Of course, the invention is not limited to the embodiment described and shown in the accompanying drawings. Modifications remain possible, in particular from the point of view of the constitution of the various elements for by substitution of technical equivalents, without thereby departing from the scope of protection of the invention.
