Description

La présente invention concerne le domaine de la chirurgie, en particulier des prothèses, et a pour objet une prothèse fémorale. L'invention a également pour objet un ancillaire correspondant. The present invention relates to the field of surgery, in particular prostheses, and relates to a femoral prosthesis. The invention also relates to a corresponding ancillary.

Actuellement, pour réaliser des prothèses de hanches, on utilise généralement des prothèses fémorales présentant, soit une surface lisse, soit une surface cruantée. Les prothèses fémorales à surface lisse sont fixées dans le fût fémoral au moyen d'un ciment. Ce dernier assure, lors de l'implantation, le comblement entre l'os et l'implant. Cependant, une prothèse de hanche cimentée comporte à terme un risque de descellement aseptique, et les difficultés opératoires se pré- sentant en cas de reprises chirurgicales, notamment l'ablation du ciment, occasionnent de très déllcats problèmes techniques. Currently, to produce hip prostheses, femoral prostheses are generally used which have either a smooth surface or a serrated surface. Femoral prostheses with smooth surfaces are fixed in the femoral barrel by means of a cement. The latter ensures, during implantation, filling between the bone and the implant. However, a cemented hip 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 serious technical problems.

Les prothèses fémorales à surface cruante, à savoir, par exemple, à couverture madréporique, ctestçà-dire présentant un surfaçage micro- et macrobillè ont permis d'obvier aux in convénients des prothèses a surface lisse en permettant une fixation sans ciment, la couverture madréporique favorisant une réhabitation osseuse sur la prothèse. Femoral prostheses with a rough surface, namely, for example, with madreporic cover, that is to say having a micro- and macrobillate surfacing have made it possible to obviate the disadvantages of prostheses with a smooth surface by allowing cementless fixation, the madreporic cover. promoting bone rehabitation on the prosthesis.

Toutefois, ces prothèses fémorales à couverture ma dréporique ne permettent pas une stabilité immédiate par autoblocage, la stabilisation définitive n'étant effective qu'après réhabitation osseuse et ossification secondaire. En outre, en cas de reprise chiruzgicale, la dépose d'une telle prothèse est rendue très difficile du fait de l'intégration intime du tissu osseux dans la surface madréporique, en particulier dans les macrobilles dont on risque un arrachement ainsi qu'une détérioration du tissu osseux. However, these femoral prostheses with dréporique coverage do not allow immediate stability by self-locking, definitive stabilization being effective only after bone rehabitation and secondary ossification. In addition, in case of surgical recovery, the removal of such a prosthesis is made very difficult due to the intimate integration of the bone tissue in the madreporic surface, in particular in the macrobeads which are at risk of tearing off as well as deterioration. bone tissue.

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 fémorale caractérisée en ce que sa tige est munie d'au moins deux surfaces opposées à macrostructure en pointes de diamant, en ce que ses surfaces s'élargissent progress#ivement à partir de la pointe de la tige en direction de la collerette du cône pour réaliser un autoblocage simultané tridimensionnel dans le plan axial, dans le plan frontal et dans le plan sagittal, en ce qu'une lame anti-rotation équipe la partie trochantérienne de la tige, cette partie trochantérienne étant munie d'un taraudage sur sa face supérieure, et en ce que le cône est un cône morse muni d'un microfiletage. It has, in fact, for its object a femoral prosthesis characterized in that its stem is provided with at least two opposite surfaces with macrostructure in diamond points, in that its surfaces widen progressively from the tip of the rod in the direction of the cone flange to achieve simultaneous three-dimensional self-locking in the axial plane, in the frontal plane and in the sagittal plane, in that an anti-rotation blade equips the trochanteric part of the rod, this trochanteric part being provided with a thread on its upper face, and in that the cone is a Morse cone provided with a micro thread.

L'invention sera mieux comprise grâce à la description ci-après, 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 en élévation frontale d'une prothèse conforme à l'invention la figure 2 est une vue en élévation latérale de la prothèse suivant la figure 1 la figure 3 est une vue partielle en plan, à plus grande échelle, de la macrostructure de surface, et la figure 4 est une vue en élévation frontale et partiellement en coupe d'un ancillaire correspondant à la prothèse. The invention will be better understood from the description below, which relates to a preferred embodiment, given by way of nonlimiting example, and explained with reference to the appended schematic drawings, in which FIG. 1 is a view in front elevation of a prosthesis according to the invention, FIG. 2 is a side elevation view of the prosthesis according to FIG. 1 FIG. 3 is a partial plan view, on a larger scale, of the surface macrostructure, and Figure 4 is a front elevational view partially in section of an ancillary corresponding to the prosthesis.

Conformément à l'invention, et comme le montrent plus particulièrement, à titre d'exemple, les figures 1 et 2 des dessins annexés, la prothèse fémorale présente une tige qui est munie de deux surfaces opposées 1 à macrostructure en pointes de diamant 2, et ses surfaces 1 et 3 s'élargissent progressivement à partir de la pointe 4 de la tige en direction de la collerette du cône 5. En outre, la partie trochantérienne de la tige est pourvue d'une lame anti-rotation 6, et, sur sa face supérieure, d'un taraudage 7, et le c8ne 5, qui est un cône morse, est muni d'un microfiletage. In accordance with the invention, and as shown more particularly, by way of example, FIGS. 1 and 2 of the appended drawings, the femoral prosthesis has a stem which is provided with two opposite surfaces 1 with a diamond-point macrostructure 2, and its surfaces 1 and 3 gradually widen from the tip 4 of the rod towards the flange of the cone 5. Furthermore, the trochanteric part of the rod is provided with an anti-rotation blade 6, and, on its upper face, with a tapping 7, and the c8ne 5, which is a Morse taper, is provided with a micro thread.

La macrostructure en pointes de diamant 2 est réalisée par un striage croisé des surfaces 1 (figure 3), et lesdites pointes de diamant 2 sont munies, en outre, d'une microstructure de surface microbillée. Cette microstructure de surface est du type à rugosité contrôlée et assure, ensemble avec la macrostructure 2, la réhabitation osseuse et l'ossifi- cation secondaire, la surface de contact avec l'os spongieux étant fortement augmentée par rapport aux prothèses connues. The macrostructure in diamond points 2 is produced by a cross-cutting of the surfaces 1 (FIG. 3), and said diamond points 2 are provided, in addition, with a microstructure of microbeaded surface. This surface microstructure is of the roughness-controlled type and, together with macrostructure 2, ensures bone rehabitation and secondary ossification, the contact surface with cancellous bone being greatly increased compared to known prostheses.

Les surfaces 1 et 3, qui s'élargissent progressive ment à partir de la pointe 4 en direction de la collerette du cône 5, assurent simultanément un autoblocage dans le plan frontal sur les surfaces 3, c'est-a-dire sur les surfaces interne et externe, dans le plan sagittal sur les surfaces 1 avant et arrière, et, en coopération, un autoblocage axial. The surfaces 1 and 3, which widen progressively from the tip 4 in the direction of the flange of the cone 5, simultaneously ensure self-locking in the frontal plane on the surfaces 3, that is to say on the surfaces internal and external, in the sagittal plane on the front and rear surfaces 1, and, in cooperation, an axial self-locking.

Ainsi, la coopération de ces surfaces 1 et 3 avec la maero- structure 2 permet l'obtention d'un autoblocage tridimensionnel primitif favorisant une réhabitation osseuse secondaire
La lame anti-rotation 6 équipant la partie trochantérienne de la tige est destinée a' améliorer la fixation primaire de la prothèse dans le fut fémoral, c'est-à-:lire à assurer une stabilité immédiate au niveau du fémur.Thus, the cooperation of these surfaces 1 and 3 with the maero-structure 2 makes it possible to obtain a primitive three-dimensional self-locking promoting a secondary bone rehabitation
The anti-rotation blade 6 fitted to the trochanteric part of the rod is intended to improve the primary fixation of the prosthesis in the femoral barrel, that is to say: read to ensure immediate stability at the femur.

Le taraudage 7 sur la face supérieure de la partie trochantérienne est prévu comme auxiliaire de positionnement lors de la mise en place de la prothèse et sert, en outre, de point d'attache d'un extracteur en cas de reprise chirurgicale éventuelle. The internal thread 7 on the upper face of the trochanteric part is provided as a positioning aid during the positioning of the prosthesis and also serves as an attachment point for an extractor in the event of possible surgical recovery.

En outre, le microfiletage équipant le cane morse 5 est destin a assurer un blocage immédiat de la bille 5', tant en rotation que dans le sens d'une extraction, grâce à un écrasement des microfilets lors de l'impaction de ladite bille 5' sur le cône 5. In addition, the micro-threading equipping the Morse cane 5 is intended to ensure immediate blocking of the ball 5 ', both in rotation and in the direction of extraction, by crushing the micro-threads during the impact of said ball 5 'on the cone 5.

L'invention a également pour objet un ancillaire fémoral sous forme d'une râpe correspondant a la prothèse décrite ci-dessus, représenté a' la figure 4 des dessins annexés, et caractérisé en ce qu'il est constitué par un corps de rape 8 présentant â sa partie supérieure une face 9 d'application d'un manche 10 ou d'une tete école 11 avec une bille fantôme 12, l'assemblage entre le corps de rSpe 8 et le manche 10 ou la tête école Il étant assuré par un dispositif démontable a' coopération de forme 13 du type & encliquetage, à verrouillage, à vissage, ou autre. The invention also relates to a femoral ancillary in the form of a rasp corresponding to the prosthesis described above, represented in FIG. 4 of the appended drawings, and characterized in that it consists of a rape body 8 having at its upper part a face 9 for applying a handle 10 or a school head 11 with a phantom ball 12, the assembly between the rSpe body 8 and the handle 10 or the school head It being provided by a detachable device with form 13 cooperation of the type & latching, locking, screwing, or the like.

Ce mode de realisation d'ancillaire permet la mise en oeuvre de râpes de tailles variables avec un manche unique pour la préparation du fflt fémoral, la râpe servant, en outre, après détermination de la taille de tige adaptée, de prothèse fantôme, En effet, la râpe peut être désolidarisée de son manche 10 après mise en place dans le fût fémoral, et une tête école il peut ttre montée sur la face 9 du corps de rSpe 8 par simple encliquetage, verrouillage, vissage, ou autre, de sorte qu'est réalisée une prothèse pante reproduisant exactement les conditions de positionnement de la future prothese. This ancillary embodiment allows the use of rasps of variable sizes with a single handle for the preparation of the femoral thread, the rasp serving, moreover, after determination of the adapted stem size, of phantom prosthesis, Indeed , the rasp can be detached from its handle 10 after being placed in the femoral barrel, and a school head can be mounted on the face 9 of the rSpe body 8 by simple snap-fastening, locking, screwing, or the like, so that 'A prosthesis is produced which reproduces exactly the positioning conditions of the future prosthesis.

Ainsi la prothèse peut être disposée définitivement, la prothèse fantôme ayant permis de vérifier au préalable l'exacti- tude de sa position ainsi que le bon choix de la bille d'articulation.The prosthesis can thus be placed definitively, the phantom prosthesis having made it possible to verify beforehand the accuracy of its position as well as the correct choice of the articulation ball.

Grâce a l'invention, il est possible de réaliser une prothèse fémorale et un ancillaire correspondant permettant une adaptation facilitée au fût fémoral et un maintien amélio- ré, tant au niveau de l'autoblocage immédiat qu'au niveau de la réhabitation osseuse et de l'ossification secondaire, tout en autorisant une extraction plus facile#en cas de reprise chirurgicale. En effet, du fait de la disposition légèrement inclinée des surfaces 1 et 3, un léger déplacement de la tige en direction d'extraction du fflt fémoral a pour conséquence une désolidarisation du tissu spongieux de l'os et de la ma- crostructure 2 en pointes de diamant à surface microbillée. Thanks to the invention, it is possible to produce a femoral prosthesis and a corresponding ancillary device allowing easier adaptation to the femoral barrel and improved maintenance, both in terms of immediate self-locking and in terms of bone rehabitation and secondary ossification, while allowing easier extraction # in case of surgical resumption. In fact, due to the slightly inclined arrangement of the surfaces 1 and 3, a slight displacement of the rod in the direction of extraction of the femoral thread results in a separation of the cancellous tissue from the bone and of the macrostructure 2 in diamond tips with micro-blasted surface.

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, ou par substitution d'équivalents techniques, sans sortir pour autant du domaine de protection de 1 t 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, or by substitution of technical equivalents, without thereby departing from the scope of protection of the invention.
