Description
La présente invention concerne un composant tibial pour une prothèse de reconstruction de l'articulation du genou. En particulier, la présente invention concerne une prothèse monocompartimentale du type "cementless" (sans ciment).The present invention relates to a tibial component for a prosthetic reconstruction of the knee joint. In particular, the present invention relates to a monocompartmental prosthesis of the type "cementless" (without cement).
Les prothèses pour la reconstruction de l'articulation du genou comprennent un composant tibial et un composant fémoral correspondant. Ces deux composants comprennent une surface interne de mise en prise avec l'os relatif à reconstruire et une surface d'articulation formée afin de remplacer, d'un point de vue anatomique, l'articulation d'origine.Prostheses for the reconstruction of the knee joint include a tibial component and a corresponding femoral component. These two components include an inner surface for engaging relative bone to be reconstructed and a hinge surface formed to anatomically replace the original joint.
Par conséquent, en particulier, un composant tibial connu comprend un élément à plaque doté d'une surface interne d'ancrage au tibia et d'une surface externe de couplage avec une surface articulaire correspondante associée au fémur et des moyens d'ancrage pour mettre en prise le composant tibial lui-même avec le tibia.Therefore, in particular, a known tibial component comprises a plate member having an internal tibial anchorage surface and an external coupling surface with a corresponding articular surface associated with the femur and anchoring means for engages the tibial component itself with the tibia.
De tels composants tibiaux sont aujourd'hui divisibles en deux groupes, c'est- à-dire ceux qui utilisent des éléments de prise adhésifs / avec ciment sur le tibia, ou bien ceux qui utilisent des moyens de fixation mécaniques. Ces derniers, juste pour se différencier des premiers, sont connus comme étant des prothèses "cementless" (sans ciment).Such tibial components are now divisible into two groups, that is, those using adhesive / cementitious grip elements on the tibia, or those using mechanical attachment means. These, just to differentiate themselves from the first, are known as "cementless" prostheses (without cement).
Dans le cas dans lequel la reconstruction de l'articulation du genou ne concerne qu'un seul des compartiments médian et latéral, la prothèse est définie comme étant monocompartimentale. De nos jours, les prothèses sans ciment, qu'elles soient monocompartimentales ou pas, utilisent en tant que moyens de fixation communs 25 des éléments filetés, par exemple, de véritables vis ou ses propres vis, qui mettent en prise, dans le siège, la plaque du composant tibial. Une telle astuce offre, d'un côté, de meilleures garanties en termes de durée stable du couplage par rapport à l'utilisation d'additifs de prise tels des additifs adhésifs / avec ciment, qui à la longue, peuvent en effet perdre leur effet et 30 provoquer des détachements et des pertes d'alignement entre les composants. Toutefois, l'utilisation de simples couplages filetés, distribués aujourd'hui dans le commerce, ne permet pas les petits réglages nécessaires pour une mise en prise optimale de la prothèse sur le tibia, ni aucune liberté du point de vue du positionnement des vis par rapport à l'axe du siège relatif. 35 A partir de cette technique connue, le but de la présente invention est de réaliser un composant tibial pour une prothèse de reconstruction de l'articulation du genou qui soit une variante par rapport à ceux qui sont connus.In the case where the reconstruction of the knee joint concerns only one of the medial and lateral compartments, the prosthesis is defined as being monocompartmental. Nowadays, cementless prostheses, whether monocompartmental or not, use as common fastening means 25 threaded elements, for example, real screws or its own screws, which engage in the seat, the plate of the tibial component. Such a trick offers, on the one hand, better guarantees in terms of the stable duration of the coupling compared with the use of setting additives such as adhesive / cement additives, which in the long run may indeed lose their effect. and cause detachments and misalignments between the components. However, the use of simple threaded couplings, distributed today commercially, does not allow small adjustments necessary for optimal engagement of the prosthesis on the shin, nor any freedom from the point of view of the positioning of the screws by relative to the relative seat axis. From this known technique, the object of the present invention is to provide a tibial component for a knee joint reconstruction prosthesis which is an alternative to those which are known.
En particulier, le but de la présente invention est de réaliser un composant tibial qui: garantit une meilleure stabilité principale immédiatement après l'intervention et secondaire dans le temps, en favorisant la croissance osseuse; réduit le risque de desserrage de l'implant; permet de réaliser des réglages d'alignement entre les vis et la plaque du composant ou au moins augmente la liberté de positionnement de la vis par rapport à l'axe du siège relatif. Selon l'aspect général de l'invention, ces avantages sont atteints de manière innovante, en proposant: un couplage de type sphérique entre le trou débouchant 15 et la tête 17 de l'élément fileté 14 afin de permettre un premier couplage réciproque par encliquetage selon une pluralité d'inclinaisons a de l'élément fileté 14 par rapport à l'axe A du trou débouchant15; des moyens pour le blocage 18 de l'élément fileté 14 selon une inclinaison a choisie. D'autres caractéristiques de l'invention prévoient que : ladite tête dudit élément fileté présente un profil sphérique de couplage avec un siège sphérique correspondant agencé dans ledit trou débouchant. le couplage par encliquetage entre ladite tête dudit élément fileté et ledit siège sphérique est réalisé au moyen d'une saillie annulaire (20) agencée au-dessus dudit siège sphérique. lesdits moyens de blocage dudit élément fileté selon une inclinaison (a) choisie par rapport audit axe (A) dudit trou débouchant comprennent un élément d'expansion de ladite tête dudit élément fileté contre les parois dudit siège sphérique. lesdits moyens de blocage comprennent une vis de blocage associée dans un siège agencé dans ladite tête dudit élément fileté et configurée de sorte que pendant le serrage, elle agit en pression progressive contre les parois internes de ladite tête dudit élément fileté. ladite vis de blocage et lesdites parois internes de ladite tête dudit élément fileté (14) comprennent des profils couplés par coin pour transformer le mouvement axial de ladite vis de blocage en expansion radiale de ladite tête dudit élément fileté Les caractéristiques et les avantages d'un composant tibial pour une prothèse de reconstruction de l'articulation du genou selon la présente invention ressortiront plus clairement d'après la description suivante, proposée à titre d'exemple et non limitative, en référence aux dessins joints, dans lesquels: la figure 1 est une vue en perspective en éclaté d'un composant tibial selon la présente invention; la figure 2 est une vue en coupe d'un composant tibial assemblé selon la présente invention; les figures 3 à 5 sont des vues de l'élément fileté proposé par la présente invention; et les figures 6 à 8 sont des vues de l'élément fileté associé au siège relatif à 10 différents stades de montage de la prothèse. En référence aux figures, le numéro de référence 10 indique un composant tibial pour une prothèse de reconstruction de l'articulation du genou selon la présente invention. En général, la présente invention trouve son application optimale dans les 15 prothèse monocompartimentales, mais peut également être utilisée pour des prothèses qui concernent à la fois les compartiments médian et latéral. Un tel composant tibial 10 comprend: un élément à plaque 11 doté d'une surface interne d'ancrage 12 au tibia et d'une surface externe de couplage 13 avec une surface correspondante pour 20 l'articulation de la prothèse du genou associée au fémur; des moyens d'ancrage 14 pour mettre en prise le composant tibial 10 avec le tibia. D'une manière connue en soi, de tels moyens d'ancrage 14 comprennent au moins, non seulement un élément fileté 14 mais également un élément à plaque 11 25 au moins doté d'un trou débouchant 15 doté d'un axe A et configuré pour permettre le passage du corps 16 de l'élément fileté 14 et pour en bloquer la tête 17. De façon tout à fait innovante, selon la présente invention, le trou débouchant 15 et la tête 17 de l'élément fileté 14 sont configurés afin de réaliser un couplage du type sphérique pour permettre un premier couplage réciproque par encliquetage 30 selon une pluralité d'inclinaisons a de l'élément fileté 14 par rapport à l'axe A du trou débouchant 15. Sur la figure 1, on représente un écart possible de l'axe B de la vis 14 par rapport à l'axe A du trou 15. Un tel couplage axial permet d'une part d'effectuer de petites corrections 35 d'alignement et d'autre part, d'augmenter la liberté de positionnement de la vis par rapport à l'axe du siège relatif.In particular, the object of the present invention is to provide a tibial component which: guarantees better main stability immediately after the intervention and secondary in time, promoting bone growth; reduces the risk of loosening the implant; allows to make alignment adjustments between the screws and the component plate or at least increases the freedom of positioning of the screw relative to the axis of the relative seat. According to the general aspect of the invention, these advantages are achieved in an innovative manner, by proposing: a spherical type coupling between the through-hole 15 and the head 17 of the threaded element 14 in order to allow a first reciprocal snap coupling at a plurality of inclinations a of the threaded element 14 with respect to the axis A of the through-hole 15; means for locking 18 of the threaded element 14 according to a chosen inclination. Other features of the invention provide that: said head of said threaded element has a spherical coupling profile with a corresponding spherical seat arranged in said through hole. the snap coupling between said head of said threaded member and said spherical seat is effected by means of an annular projection (20) arranged above said spherical seat. said locking means of said threaded member at an inclination (a) selected from said axis (A) of said through hole comprises an expansion member of said head of said threaded member against the walls of said spherical seat. said locking means comprise an associated locking screw in a seat arranged in said head of said threaded member and configured so that during clamping it acts in progressive pressure against the inner walls of said head of said threaded member. said locking screw and said inner walls of said head of said threaded member (14) comprise wedge-coupled profiles for transforming the axial movement of said radial expansion locking screw of said head of said threaded member. The features and advantages of a tibial component for a knee joint reconstruction prosthesis according to the present invention will emerge more clearly from the following description, given by way of example and not limitation, with reference to the accompanying drawings, in which: FIG. an exploded perspective view of a tibial component according to the present invention; Figure 2 is a sectional view of an assembled tibial component according to the present invention; Figures 3 to 5 are views of the threaded member proposed by the present invention; and Figures 6 to 8 are views of the threaded member associated with the seat relative to different stages of mounting the prosthesis. With reference to the figures, reference numeral 10 indicates a tibial component for a knee joint reconstruction prosthesis according to the present invention. In general, the present invention finds its optimum application in monocompartmental prostheses, but can also be used for prostheses which concern both the medial and lateral compartments. Such a tibial component 10 comprises: a plate member 11 having an inner tibia anchoring surface 12 and an outer coupling surface 13 with a corresponding surface for the knee prosthesis joint associated with the femur ; anchoring means 14 for engaging the tibial component 10 with the tibia. In a manner known per se, such anchoring means 14 comprise at least not only a threaded element 14 but also a plate element 11 at least 25 having a through hole 15 having an axis A and configured to allow the passage of the body 16 of the threaded element 14 and to block the head 17. In a completely innovative manner, according to the present invention, the through hole 15 and the head 17 of the threaded element 14 are configured so as to spherical coupling to allow a first snap-in mutual coupling 30 at a plurality of inclinations a of the threaded member 14 with respect to the axis A of the through-hole 15. In FIG. B axis 14 of the screw 14 with respect to the axis A of the hole 15. Such an axial coupling makes it possible, on the one hand, to make small alignment corrections and, on the other hand, to increase the freedom of positioning of the screw relative to the axis of the si relative age.
On prévoit ensuite des moyens pour le blocage 18 de l'élément fileté 14 selon une inclinaison (a) choisie par rapport à l'axe A du trou débouchant 15. De cette façon, les déplacements axiaux sont donc impossibles entre la plaque et la vis, qui ont par contre lieu avec des implants fixés avec des vis simples.Means 18 are then provided for locking the threaded element 14 in an inclination (a) chosen with respect to the axis A of the through hole 15. In this way, the axial displacements are therefore impossible between the plate and the screw , which instead take place with implants fixed with simple screws.
Ces déplacements axiaux peuvent provoquer dans le temps la mise en mouvement de la base et augmentent le risque de détachements de l'implant. En particulier, le couplage par encliquetage entre la tête 17 de l'élément fileté 14 et le siège sphérique 19 est réalisé au moyen d'une saillie annulaire 20 agencée au-dessus du siège sphérique 19.These axial displacements can cause in time the setting in movement of the base and increase the risk of detachments of the implant. In particular, the snap coupling between the head 17 of the threaded element 14 and the spherical seat 19 is achieved by means of an annular projection 20 arranged above the spherical seat 19.
De cette façon, une fois la saillie annulaire 20 dépassée, la tête 17 est bloquée dans le siège 19. Les moyens pour le blocage 18 de l'élément fileté 14 selon une inclinaison a choisie comprennent un élément d'expansion de la tête 17 de l'élément fileté 14 contre les parois du siège sphérique 19.In this way, once the annular protrusion 20 has passed, the head 17 is locked in the seat 19. The means for locking 18 of the threaded element 14 at a chosen inclination comprise an expansion element of the head 17 of FIG. the threaded element 14 against the walls of the spherical seat 19.
En particulier, de tels moyens de blocage comprennent une vis de blocage 18 associée dans un siège 21 fileté agencé dans la tête 17 de l'élément fileté 14 et configurée de sorte que pendant le serrage, elle agit en pression progressive contre les parois internes de la tête 17. A son tour, la tête 17 entre ainsi en contact forcé contre les parois du siège 19, se bloquant par friction. En particulier, les parois internes de la tête 17 de l'élément fileté 14 et les parois externes de la vis 18 comprennent des profils 22, 23 couplés par coin pour transformer le mouvement axial de la vis de blocage 18 en expansion radiale de la tête 17 de l'élément fileté 14. Des détails ultérieurs complètent l'invention, non seulement, comme le fait de 25 prévoir la tête sphérique 17 réalisée avec des bords pour obtenir une meilleure élasticité, mais également le choix des matériaux utilisés comme l'alliage de cobalt chrome pour la plaque 11 et l'alliage de titane soit pour la vis principale 14, soit pour la vis de blocage. On a ainsi vu qu'un composant tibial pour une prothèse de reconstruction de 30 l'articulation du genou selon la présente invention réalise les buts mis précédemment en évidement. En effet, le composant tibial de la présente invention offre une solution en variante aux composants utilisés aujourd'hui, et en même temps, propose de nombreux avantages, tels que: 35 la garantie d'une meilleure stabilité principale immédiatement après l'intervention et secondaire dans le temps, en favorisant la croissance osseuse; la réduction du risque de desserrage de l'implant; la possibilité de réaliser des réglages d'alignement entre les vis et la plaque du composant ou au moins augmenter la liberté du point de vue du positionnement de la vis par rapport à l'axe du siège relatif. Le composant tibial pour une prothèse de reconstruction de l'articulation du genou de la présente invention ainsi conçue est susceptible de subir de nombreuses modifications et variantes, toutes se trouvant dans le même concept novateur; en outre, tous les détails peuvent être remplacés par des éléments techniquement équivalents. En pratique, non seulement les matériaux utilisés mais également leurs dimensions, peuvent être d'un type quelconque selon les exigences techniques.10In particular, such locking means comprise a locking screw 18 associated in a threaded seat 21 arranged in the head 17 of the threaded element 14 and configured so that during clamping, it acts in progressive pressure against the internal walls of the head 17. In turn, the head 17 thus comes into forced contact against the walls of the seat 19, locking by friction. In particular, the inner walls of the head 17 of the threaded element 14 and the outer walls of the screw 18 comprise wedge-coupled profiles 22, 23 for transforming the axial movement of the locking screw 18 in radial expansion of the head. 17 of the threaded element 14. Further details complete the invention, not only as to provide the spherical head 17 made with edges to obtain a better elasticity, but also the choice of the materials used as the alloy. cobalt chromium for the plate 11 and the titanium alloy either for the main screw 14 or for the locking screw. It has thus been seen that a tibial component for a knee joint reconstruction prosthesis according to the present invention achieves the previously recessed goals. Indeed, the tibial component of the present invention offers an alternative solution to the components used today, and at the same time offers many advantages, such as: the guarantee of a better main stability immediately after the intervention and secondary in time, promoting bone growth; reducing the risk of loosening the implant; the possibility of making alignment adjustments between the screws and the component plate or at least increase the freedom from the point of view of the positioning of the screw relative to the axis of the relative seat. The tibial component for a knee joint reconstruction prosthesis of the present invention so conceived is susceptible to many modifications and variations, all in the same innovative concept; in addition, all details may be replaced by technically equivalent elements. In practice, not only the materials used but also their dimensions, can be of any type according to the technical requirements.
