Abstract
Description
La présente invention concerne les prothèses du genou et a pour objet une prothèse fémoro-patellaire, adaptée à remplacer la surface articulaire de la face antérieure de l'extrémité inférieure du fémur soit la trochlée, et la surface articulaire de la face postérieure de la rotule. The present invention relates to knee prostheses and relates to a femoro-patellar prosthesis, adapted to replace the articular surface of the anterior face of the lower end of the femur, ie the trochlea, and the articular surface of the posterior face of the patella. .
Les figures 1 et 2 rappellent schématiquement l'articulation d'un genou, la figure 1 vue de profil et la figure 2 vue de face antérieure de l'articulation. Figures 1 and 2 schematically recall the knee joint, Figure 1 side view and Figure 2 front view of the joint.
On a représenté le fémur,1, la rotule 2, le condyle distal 3, le tibia 4, le péroné 5. La rotule 2 est en regard de la trochlée 6. L'extrémité inférieure du fémur, volumineuse, renflée, présente sur sa face antérieure une surface articulaire en forme de poulie, la trochlée, qui s'incurve vers l'arrière et se prolonge jusqu'à l'échancrure intercondylienne, dans sa partie médiane et jusqu'aux sillons condylo-trochléens sur les parties internes et externes. L'extrémité distale et postérieure du fémur se présente en deux masses volumineuses, les condyles fémoraux distaux et postérieurs qui s'articulent avec les plateaux tibiaux, lors des mouvements de flexion, extension. Sur la figure 3, on peut observer les sillons condylo-trochléens 7. We have shown the femur, 1, the patella 2, the distal condyle 3, the tibia 4, the fibula 5. The patella 2 is opposite the trochlea 6. The lower end of the femur, bulky, swollen, present on its anterior surface a joint surface in the form of a pulley, the trochlea, which curves backwards and extends to the intercondylar notch, in its median part and to the condylo-trochlear grooves on the internal and external parts . The distal and posterior end of the femur is presented in two bulky masses, the distal and posterior femoral condyles which articulate with the tibial plates, during the movements of flexion, extension. In Figure 3, we can observe the condylo-trochlear grooves 7.
On connait déjà des prothèses dites tricompartimentaires qui forment des articulations d'une part entre la trochlée et la rotule, d'autre part entre les deux condyles fémoraux et les plateaux tibiaux. La mise en place d'une telle prothèse est une opération relativement complexe et longue. We already know so-called three-compartment prostheses which form joints on the one hand between the trochlea and the patella, on the other hand between the two femoral condyles and the tibial plates. The installation of such a prosthesis is a relatively complex and long operation.
ll existe par ailleurs des prothèses unicompartimentaires permettant de remplacer la surface d'un seul condyle fémoral et du plateau tibial correspondant. There are also unicompartmental prostheses to replace the surface of a single femoral condyle and the corresponding tibial plateau.
Conformément à la présente invention, une prothèse de genou, qui se compose de la partie trochléenne du fémur, et s'articule avec la face postérieure de la rotule, est caractérisée en ce qu'elle comporte une partie supérieure antérieure prévue pour être appliquée sur la face frontale inférieure du fémur ayant fait l'objet d'une ostéotomie et une partie inférieure, recourbée vers l'arrière, sensiblement perpendiculaire, le bord de la partie inférieure étant limité au niveau de l'échancmre intercondylienne, dans la zone médiane et suivant les sillons condylo-trochléens dans les zones internes et externes. According to the present invention, a knee prosthesis, which consists of the trochlear part of the femur, and articulates with the posterior face of the patella, is characterized in that it comprises an upper upper part intended to be applied to the lower frontal face of the femur having been the subject of an osteotomy and a lower part, curved backwards, substantially perpendicular, the edge of the lower part being limited to the level of the intercondylar notch, in the median zone and following the condylo-trochlear grooves in the internal and external zones.
Cette prothèse assure un contact permanent avec la rotule, qui recevra sur sa face postérieure ostéotomisée un bouton rotulien prothétique, en évitant tout conflit fémoropatellaire dans les positions de flexion et d'extension tout en guidant parfaitement la rotule dans son logement durant les mouvements de flexion-extension. This prosthesis ensures permanent contact with the patella, which will receive on its osteotomized posterior face a prosthetic patellar button, avoiding any femoropatellar conflict in the flexion and extension positions while perfectly guiding the patella in its housing during the flexion movements. -extension.

On a représenté une prothèse fémorale 8 selon l'invention mise en place sur le fémur de la figure 3. A femoral prosthesis 8 according to the invention has been shown placed on the femur of FIG. 3.
Cette prothèse fémorale est représentée suivant trois directions d'observation sur les figures 4, S et 6. This femoral prosthesis is represented in three directions of observation in FIGS. 4, S and 6.
La prothèse fémorale comporte une partie frontale 9, délimitée sur la face postérieure, placée en contact avec l'os ostéotomisé par une surface plane 10, et une partie distale 11 délimitée elle-aussi par une surface plane 12 dans sa partie médiane et rayonnée sur les parties interne et externe. Les deux surfaces 10 et 12 sont raccordées par une surface 13 présentant un rayon de courbure approprié. Sur la figure 5, on a représenté en traits interrompus le profil 14 d'une prothèse fémorale partie d'un genou tricompartimentaire prothétique. The femoral prosthesis comprises a front part 9, delimited on the posterior face, placed in contact with the osteotomized bone by a flat surface 10, and a distal part 11 also delimited by a flat surface 12 in its median part and radiated on the internal and external parts. The two surfaces 10 and 12 are connected by a surface 13 having an appropriate radius of curvature. In Figure 5, there is shown in broken lines the profile 14 of a femoral prosthesis part of a three-compartment prosthetic knee.
La partie frontale 9, vue en plan sur la figure 4 correspond à la partie inférieure du fémur qui présente un élargissement à son extrémité, et a à peu près la forme générale d'un trapèze. La face postérieure 10 est plane pour s'adapter à l'os ostéotomisé. La partie distale 11 est plus courte et moins large (figures 5 et 6) et a une forme générale triangulaire. Les deux bords interne et externe 15, 16 dans ce plan font un angle a d'environ 80 , et les extrémités postérieures lisa, 16a sont séparées par une courbe 17 qui s'adapte à l'échancrure intercondylienne.La position de cette courbe 17 et de ces deux lignes 15, 16 qui se placent sur les sillons condylo-trochléens, à la séparation des condyles et de la trochlée, est une caractéristique importante de la présente invention, en ce qu'elle permet une application pemlanente de la rotule prothétique contre la prothèse, qui permet d'éviter tout conflit rotulien aux deux interfaces trochlée prothétique et condyles distaux. The front part 9, seen in plan in Figure 4 corresponds to the lower part of the femur which has a widening at its end, and has roughly the general shape of a trapezoid. The posterior face 10 is flat to adapt to the osteotomized bone. The distal part 11 is shorter and narrower (Figures 5 and 6) and has a generally triangular shape. The two internal and external edges 15, 16 in this plane make an angle a of approximately 80, and the posterior ends lisa, 16a are separated by a curve 17 which adapts to the intercondylar notch. The position of this curve 17 and of these two lines 15, 16 which are placed on the condylo-trochlear grooves, at the separation of the condyles and the trochlea, is an important characteristic of the present invention, in that it allows a pemlanent application of the prosthetic patella against the prosthesis, which avoids any patellar conflict at the two prosthetic trochlea interfaces and distal condyles.
On a représenté en traits interrompus le profil 14 d'une prothèse fémorale tricompartimentaire, adapté au même genou. C'est un avantage important de la prothèse de la présente invention qui peut être le premier temps d'une prothèse tricompartimentaire. The line 14 of a three-compartment femoral prosthesis, adapted to the same knee, has been shown in broken lines. This is an important advantage of the prosthesis of the present invention which may be the first step in a three-compartment prosthesis.
En effet, il n'y a pas de modification de coupe si l'on veut implanter une prothèse tricompartimentaire après la prothèse fémoro-patellaire, ou si la nécessité s'en faisait ressentir soit en cas de reprise, soit durant l'intervention.Indeed, there is no modification of cut if one wants to implant a three-compartment prosthesis after the femoro-patellar prosthesis, or if the need arose either in case of recovery, or during the intervention.
Sur la figure 5, on a représenté un plot d'ancrage 18 qui peut être fixe ou amovible le plot amovible peut comporter une cheville qui vient se placer dans un trou prévu dans la surface 12 de la partie distale de la prothèse. Plusieurs trous peuvent être prévus afin d'obtenir plusieurs positions de la cheville. Ceci permet de latéraliser plus ou moins le carter fémoral de la prothèse de façon à éviter les problèmes de stabilité fémoro-patellaire, notamment une luxation de la rotule, ce qui est très utile en cas d'arthrose fémoropatellaire secondaire à une desaxation rotulienne. Le plot peut être placé normalement sur l'axe V-V de la figure 4. In Figure 5, there is shown an anchoring pad 18 which can be fixed or removable the removable pad may include a pin which is placed in a hole provided in the surface 12 of the distal part of the prosthesis. Several holes can be provided in order to obtain several positions of the anchor. This makes it possible to lateralize more or less the femoral casing of the prosthesis so as to avoid problems of femoro-patellar stability, in particular a dislocation of the patella, which is very useful in case of femoropatellar osteoarthritis secondary to a patellar desaxation. The stud can be placed normally on the V-V axis in Figure 4.
La prothèse peut être réalisée en tout matériau usuel pour ce genre d'application, notamment en titane ou cobalt-chrome. The prosthesis can be made of any usual material for this kind of application, in particular titanium or cobalt-chromium.
