PROTHESE TEXTILE DE LIGAMENT CROISE
ANTERIEUR DU GENOU
La présente invention a trait à une prothèse textile perfectionnée destinée à remplacer le ligament croisé antérieur du genou humain.TEXTILE PROSTHESIS OF CROSSED LIGAMENT
PREVIOUS KNEE
The present invention relates to an improved textile prosthesis intended to replace the anterior cruciate ligament of the human knee.
On sait déjà depuis quelques années remplacer le ligament croisé antérieur du genou par un élément tressé ou tissé dans un matériau biocompatible. Une telle prothèse est passée dans un tunnel osseux préalablement creusé dans le tibia puis dans un tunnel osseux fémoral ou fixé autour du condyle fémoral. It has already been known for a few years to replace the anterior cruciate ligament of the knee with a braided or woven element in a biocompatible material. Such a prosthesis is passed through a bone tunnel previously dug into the tibia and then into a femoral bone tunnel or fixed around the femoral condyle.
Cependant, la fixation aux extrémités supérieure et inférieure de la prothèse a toujours posé un problème. On a utilisé des agrafes, des vis, des poulies, etc..., mais on n'a pas trouvé de système intégrant les fixations supérieure et inférieure à la prothèse elle-meme. However, attachment to the upper and lower ends of the prosthesis has always been a problem. We used staples, screws, pulleys, etc ..., but we did not find a system integrating the upper and lower fixings to the prosthesis itself.
Le but de l'invention est de perfectionner ce type de prothèse, d'une part, au plan de ses performances et de sa tenue mécaniques et, d'autre part, au plan de sa fixation à ses deux extrémités dans la masse osseuse. The object of the invention is to improve this type of prosthesis, on the one hand, in terms of its performance and mechanical strength and, on the other hand, in terms of its attachment to its two ends in the bone mass.
A cet effet, l'invention a pour objet une prothèse textile de ligament croisé antérieur du genou, caractérisée en ce qu'elle est constituée d'au moins deux brins en matériau textile biocompatible disposés sensiblement en parallèle en étant raccordés à chaque extrémité à une vis susceptible d'être engagée dans un puits osseux ménagé respectivement dans le fémur et dans le tibia, chaque vis étant munie d'un évidement axial sur au moins une partie de sa longueur, conformé de façon à recevoir un outil de vissage approprié. To this end, the invention relates to a textile prosthesis of the anterior cruciate ligament of the knee, characterized in that it consists of at least two strands of biocompatible textile material arranged substantially in parallel by being connected at each end to a screw capable of being engaged in a bone well formed respectively in the femur and in the tibia, each screw being provided with an axial recess over at least part of its length, shaped so as to receive an appropriate screwing tool.
Suivant un mode de réalisation préféré, la prothèse comporte quatre brins répartis régulièrement en étant fixés par tous moyens appropriés à la périphérie externe d'un prolongement tubulaire de chaque vis d'extrémité. According to a preferred embodiment, the prosthesis comprises four strands distributed regularly by being fixed by any appropriate means to the external periphery of a tubular extension of each end screw.
Avantageusement, ledit prolongement tubulaire des vis, à cet effet, comporte extérieurement une surface cannelée axialement recevant dans chaque cannelure un brin. Advantageously, said tubular extension of the screws, for this purpose, externally comprises an axially grooved surface receiving in each groove a strand.
La fixation des brins au droit de chaque vis se fait par exemple par sertissage d'une bague entourant ledit prolongement tubulaire des vis avec leurs brins. The strands are fixed to the right of each screw, for example by crimping a ring surrounding said tubular extension of the screws with their strands.
La vis destinée au puits osseux fémoral est avantageusement constituée d'une partie antérieure filetée et d'une partie postérieure tubulaire sur laquelle sont fixés lesdits brins textiles et dont le profil interne est déterminé pour recevoir ledit outil de vissage approprié, cependant que la vis tibiale est avantageusement constituée d'une partie antérieure constituant ladite partie tubulaire sur laquelle sont fixés lesdits brins textiles et d'une partie postérieure filetée creuse dont le profil est déterminé pour recevoir ledit outil de vissage approprié. The screw intended for the femoral bone well advantageously consists of a threaded anterior part and a tubular posterior part on which said textile strands are fixed and whose internal profile is determined to receive said appropriate screwing tool, while the tibial screw advantageously consists of a front part constituting said tubular part on which said textile strands are fixed and of a hollow threaded rear part whose profile is determined to receive said suitable screwing tool.
Les brins sont par exemple constitués de tresses de fibres de polypropylène. The strands are for example made of braids of polypropylene fibers.
Une telle prothèse est simple de fabrication et aisée de mise en place. Such a prosthesis is simple to manufacture and easy to set up.
La fixation de la prothèse dans des tunnels osseux fémoral et tibial est optimale et il est possible de régler à volonté, par vissage de l'une ou l'autre des vis, la tension des brins ainsi que leur torsion. The fixation of the prosthesis in femoral and tibial bone tunnels is optimal and it is possible to adjust at will, by screwing one or the other of the screws, the tension of the strands as well as their twist.
Tous les éléments d'ancrage d'une telle prothèse sont noyés dans la masse osseuse ce qui évite toutes douleurs postopératoires dues à des éléments saillants sur les surfaces osseuses. All the anchoring elements of such a prosthesis are embedded in the bone mass which avoids any postoperative pain due to protruding elements on the bone surfaces.
Enfin, les quatre brins indépendants assurent une stabilité parfaite de l'articulation et une sécurité totale, la résistance nécessaire de la prothèse étant conservée même au cas où deux des quatre brins se rompaient. Finally, the four independent strands ensure perfect stability of the joint and total security, the necessary strength of the prosthesis being preserved even in the event that two of the four strands break.
D'autres caractéristiques et avantages de l'invention ressortiront de la description qui va suivre d'un mode de réalisation donné à titre d'exemple uniquement et en regard du dessin annexé sur lequel

La prothèse représentée sur les Figures 1 à 4 comporte quatre brins identiques 1 constitués de fibres tressées ou tissées. en un matériau biocompatible, par exemple du polypropylène, disposés sensiblement en parallèle en étant raccordés, à leurs deux extrémités, sur la périphérie externe de deux parties métalliques tubulaires 2 et 3, respectivement d'une vis fémorale 4 et d'une vis tibiale 5. The prosthesis shown in Figures 1 to 4 has four identical strands 1 made of braided or woven fibers. of a biocompatible material, for example polypropylene, arranged substantially in parallel by being connected, at their two ends, to the external periphery of two tubular metal parts 2 and 3, respectively of a femoral screw 4 and a tibial screw 5 .
Chaque brin 1 est par exemple de forme cylindrique et de préférence tubulaire bien que pouvant être éventuellement plein, et terminé à chaque extrémité par un renflement 6 réalisé par soudage, de solidarisation des extrémités des fibres. Each strand 1 is for example of cylindrical shape and preferably tubular although it can possibly be full, and terminated at each end by a bulge 6 produced by welding, for securing the ends of the fibers.
Les brins 1 sont de préférence répartis régulièrement à la périphérie des parties tubulaires 2 et 3 en étant reçus dans des cannelures 7 ménagées suivant des génératrices desdites parties tubulaires 2, 3. The strands 1 are preferably distributed regularly at the periphery of the tubular parts 2 and 3, being received in grooves 7 formed along generatrices of said tubular parts 2, 3.
Les brins 1 sont maintenus en place dans les cannelures 7 par sertissage d'une bague 8 enfilée sur chaque partie 2, 3 et coinçant lesdits brins 1 à proximité immédiate des renflements 6. Le diamètre des brins 1 est sensiblement supérieur à la profondeur des cannelures en sorte que le sertissage des bagues 8, associé aux renflements 6 de retenue des brins, assure un blocage parfait de ces derniers sur les vis d'ancrage 4, 5. The strands 1 are held in place in the grooves 7 by crimping a ring 8 threaded on each part 2, 3 and wedging said strands 1 in the immediate vicinity of the bulges 6. The diameter of the strands 1 is substantially greater than the depth of the grooves so that the crimping of the rings 8, associated with the bulges 6 for retaining the strands, ensures perfect blocking of the latter on the anchoring screws 4, 5.
Le matériau des vis 4, 5 et des bagues 8 est un matériau biocompatible, par exemple en acier inoxydable austénitique. The material of the screws 4, 5 and of the rings 8 is a biocompatible material, for example made of austenitic stainless steel.
Les parties tubulaires 2 et 3 sont des prolongements de deux vis d'ancrage 4, 5 dont les filets 9 présentent un diamètre sensiblement supérieur à celui de l'ensemble parties 2, 3 - bague 8 - brins 1, de façon que tout le système de fixation des extrémités des brins 1 puisse être engagé dans deux tunnels osseux ménagés dans le fémur et le tibia respectivement. The tubular parts 2 and 3 are extensions of two anchor screws 4, 5 whose threads 9 have a diameter substantially greater than that of the assembly of parts 2, 3 - ring 8 - strands 1, so that the entire system for fixing the ends of the strands 1 can be engaged in two bone tunnels formed in the femur and the tibia respectively.
Les vis fémorale 4 et tibiale 5 n'ont pas la même morphologie du fait de leur mode différent d'insertion dans leur puits osseux récepteur. The femoral 4 and tibial 5 screws do not have the same morphology because of their different mode of insertion into their receptor bone well.
La vis fémorale 4 comporte une partie antérieure filetée conique 10 et percée d'un canal central il destiné au passage d'une broche de guidage de la vis 4. The femoral screw 4 has a conical threaded front part 10 and pierced with a central channel 11 intended for the passage of a guide pin for the screw 4.
La partie postérieure de la vis 4 est constituée par ladite partie tubulaire 2 porte-brins dont la section interne est conformée, par exemple une empreinte centrale hexagonale 12, pour recevoir une clé ou analogue permettant de visser ou dévisser la vis 4 dans son logement osseux. The rear part of the screw 4 is constituted by said tubular part 2 strand holders whose internal section is shaped, for example a central hexagonal imprint 12, to receive a key or the like allowing to screw or unscrew the screw 4 in its bone housing .
La vis tibiale 5 comporte une partie antérieure constituée par la partie tubulaire 3 porte-brins et une partie postérieure 13 filetée et creuse, en sorte de définir une empreinte centrale par exemple hexagonale 14 susceptible de recevoir un outil de vissage-dévissage approprié. The tibial screw 5 has an anterior part constituted by the tubular part 3 strand holders and a posterior part 13 threaded and hollow, so as to define a central cavity, for example hexagonal 14 capable of receiving an appropriate screwing-unscrewing tool.
La mise en place de la prothèse s'opère de la manière suivante. The prosthesis is put in place as follows.
La vis fémorale 4 est tout d'abord engagée dans l'orifice inférieur du tunnel osseux ménagé dans le tibia en étant guidée par une broche insérée à cet effet dans le canal 11. La vis 4 est vissée dans ce tunnel grâce à un tournevis dont la lame traverse de part en part la vis tibiale 5 en sorte d'accéder à l'empreinte 12 de ladite vis 4. La vis fémorale 4 est ainsi, après traversée du tunnel tibial, insérée et vissée dans son puits récepteur fémoral, cependant que la vis tibiale 5 est mise en place dans le tunnel tibial à l'aide d'un autre tournevis dont l'extrémité est adaptée à l'empreinte 14. The femoral screw 4 is first of all engaged in the lower orifice of the bone tunnel formed in the tibia while being guided by a pin inserted for this purpose in the channel 11. The screw 4 is screwed into this tunnel using a screwdriver, the blade passes right through the tibial screw 5 so as to access the imprint 12 of said screw 4. The femoral screw 4 is thus, after crossing the tibial tunnel, inserted and screwed into its femoral receptor well, while the tibial screw 5 is placed in the tibial tunnel using another screwdriver, the end of which is adapted to the imprint 14.
Avantageusement, le diamètre des filets 9 de la vis fémorale 4 est légèrement inférieur à celui des filets 9 de la vis tibiale 5 pour faciliter le transit de la vis fémorale 4 dans le tunnel tibial et ne pas porter atteinte à l'intégrité du taraudage dudit tunnel tibial.Advantageously, the diameter of the threads 9 of the femoral screw 4 is slightly less than that of the threads 9 of the tibial screw 5 to facilitate the transit of the femoral screw 4 in the tibial tunnel and not to affect the integrity of the tapping of said thread. tibial tunnel.
La présente invention est remarquable en ce qu'elle ne comporte aucun élément extra-osseux à la prothèse, tout le système d'ancrage de cette dernière étant noyé dans la masse osseuse, ce qui évite les douleurs post-opératoires dues à des éléments saillants sur les surfaces osseuses. The present invention is remarkable in that it has no extra-bony element to the prosthesis, the whole anchoring system of the latter being embedded in the bone mass, which avoids post-operative pain due to projecting elements. on bone surfaces.
Le dispositif de l'invention permet de régler à la demande la tension ainsi que la torsion des brins 1 en jouant sur la position des vis 4, 5 dans les tunnels ou puits osseux, à la fois axialement dans ces derniers et angulairement. The device of the invention makes it possible to adjust the tension as well as the torsion of the strands 1 on request by varying the position of the screws 4, 5 in the tunnels or bone wells, both axially in the latter and angularly.
Les quatre brins 1, de préférence tressés, sont indépendants et assurent une stabilité parfaite de l'articulation, même si l'un d'entre eux casse. The four strands 1, preferably braided, are independent and ensure perfect stability of the joint, even if one of them breaks.
Par mesure de sécurité, on réalise les brins 1 en sorte d'obtenir, même en cas de rupture de deux d'entre eux, un résistance satisfaisante de la prothèse. As a safety measure, the strands 1 are made so as to obtain, even in the event of rupture of two of them, satisfactory resistance of the prosthesis.
Bien que le mode de réalisation représenté et décrit comporte quatre brins 1, disposés symétriquement par rapport à l'axe général A de la prothèse, on pourrait envisager de prévoir un nombre de tels brins différent, inférieur ou supérieur à quatre, selon la nature du brin et de son matériau constitutif, les parties tubulaires 2, 3 porte-brins étant aménagées en conséquence et de préférence de façon à répartir les brins régulièrement ou symétriquement à la périphérie desdites parties tubulaires 2, 3. Although the embodiment shown and described comprises four strands 1, arranged symmetrically with respect to the general axis A of the prosthesis, it could be envisaged to provide a number of such strands different, less than or greater than four, depending on the nature of the strand and its constituent material, the tubular parts 2, 3 strand carriers being arranged accordingly and preferably so as to distribute the strands regularly or symmetrically around the periphery of said tubular parts 2, 3.
Enfin, l'invention n'est évidemment pas limitée audit mode de réalisation, mais en couvre au contraire toutes les variantes, notamment en ce qui concerne les agencement, forme et dimensions des parties porte-brins (2, 3), des éléments (bagues 8) de sertissage ou autre mode de fixation des brins sur lesdites parties porte-brins, ainsi que des vis d'ancrage dans les tunnels osseux fémoral et tibial. Finally, the invention is obviously not limited to said embodiment, but on the contrary covers all variants thereof, in particular as regards the arrangement, shape and dimensions of the strand-carrying parts (2, 3), of the elements ( 8) crimping rings or other method of fixing the strands on said strand-carrying parts, as well as anchoring screws in the femoral and tibial bone tunnels.
