Abstract

A cruciate ligament prosthesis which maintains the functional isometrics of the knee while preventing bone problems therein. The prosthesis consists of a flexible cable (1) of which one end is hinged to a pivot (2) implanted in the condylus while its other end is attached to the tibia via a length-adjusting arrangement (5, 6, 7). Said prosthesis is particularly suitable for sportspersons with a torn cruciate ligament who are required to resume their normal activities promptly.

Description

PROTHESE ARTICULEE DE LIGAMENT CROISE DU GENOU HUMAINARTICULATED PROSTHESIS OF HUMAN KNEE CROSS LIGAMENT
La présente invention est destinée à remplacer un ligament croisé naturel du genou humain dont la défaillance provogue un handicap important et peut générer de l'arthrose. II existe actuellement deux voies dans la chirurgie des ligaments croisés.The present invention is intended to replace a natural cruciate ligament of the human knee, the failure of which provokes a significant handicap and can generate osteoarthritis. There are currently two routes in cruciate ligament surgery.
- Les auto-plasties : le ligament est remplacé par une partie d'un des tendons du genou. Si cette technique . pose pas de problème de biocompatibi- lité, i* 'ameure des risques d'étirement et une fragilisation du tendon sur lequel est prélevé l'implant.- Self-plasty: the ligament is replaced by part of one of the knee tendons. If this technique. not a problem of biocompatibi- ity, i * 'ameure risks stretching and weakening of the tendon which is taken the implant.
- Les ligaments prothétiques : ils sont réalisés à l'aide de fibres flexibles synthétiques. Si la fixation sur le tibia ne pose pas de gros problèmes,1a fixation fémorale plus délicate, s'oriente sur deux voies :- Prosthetic ligaments: they are made using flexible synthetic fibers. If the fixation on the tibia does not pose big problems, the more delicate femoral fixation is oriented in two ways:
- dans un tunnel trans-osseux condylien, ce qui respecte l'isométrie mais pose des problèmes d'usure du tunnel et d'interférence avec le bord du condyle.- in a condylar transosseous tunnel, which respects the isometry but poses problems of wear of the tunnel and interference with the edge of the condyle.
- en "over the top" où l'isométrie n'est plus respectée ce qui peut donner des limitations en flexion ou en extension. Ces ligaments peuvent poser des problèmes de tolérance; de plus, la tenue au vieillissement en milieu synovial es\ mal connue.- in "over the top" where the isometry is no longer respected which can give limitations in flexion or extension. These ligaments can cause tolerance problems; moreover, the resistance to aging in a synovial environment is poorly understood.
Par la présente invention, on se propose de remédier aux principaux inconvénients des solutions actuelles.By the present invention, it is proposed to remedy the main drawbacks of current solutions.
L'extrémité fémorale du ligament compor a une boucle qui vient s'articuler autour d'un pivot implanté dans le condyle. Cette articulation permet d éviter l'abrasion du condyle et de conserver l'isométrie de fonctionnement du genou.The femoral end of the compor ligament has a loop which is articulated around a pivot implanted in the condyle. This articulation makes it possible to avoid abrasion of the condyle and to maintain the isometric functioning of the knee.
L'extrémité tibiale comporte un système vis-écrou qui permet de régler la longueur du ligament. L'utilisation de matériaux métalliques permet de minimiser les risques d'allergie.The tibial end has a screw-nut system that adjusts the length of the ligament. The use of metallic materials minimizes the risk of allergy.
Dans la description qui suit, on se réfère aux dessins annexés, dans lesquels : - les figures 1 et 2 représentent, en coupes partielles respectivement de profil et de face, un genou en extension équipé du dispositif.In the description which follows, reference is made to the appended drawings, in which: - Figures 1 and 2 show, in partial sections respectively in profile and in front, a knee in extension equipped with the device.
— Les figures 3 et 4 représentent, en coupes partielles respectivement de profil et de face, un genou fléchi équipé du dispositif.- Figures 3 and 4 show, in partial sections respectively in profile and front, a bent knee equipped with the device.
- Les figures 5, 6, 7 et 8 sont des vues et des coupes agrandies de. la prothèse.- Figures 5, 6, 7 and 8 are views and enlarged sections of. the prosthesis.
La prothèse est constituée d'un cable souple (1) dont une extrémité est fixée au tibia et dont l'autre extrémité est articulée autour d'un pivot (2) .The prosthesis consists of a flexible cable (1), one end of which is fixed to the tibia and the other end of which is articulated around a pivot (2).
Ce pivot (2) est implanté dans le condyle en un point proche du centre de l'implantation naturelle du ligament croisé, perpendiculairement au plan sagittal de flexion du genou. Il est constitué d'une tige filetée entièrement noyée dans l'os, prolongée par une partie cylindrique (10) et une tête (11) qui dépassent dans l'espace intercondylien.This pivot (2) is implanted in the condyle at a point close to the center of the natural implantation of the cruciate ligament, perpendicular to the sagittal plane of knee flexion. It consists of a threaded rod fully embedded in the bone, extended by a cylindrical part (10) and a head (11) which protrude into the intercondylar space.
L'articulation du cable (l) sur le pivot (2) s'effectue par l'intermédiaire d'un coussinet (3) ajusté sur la partie cylindrique (10) ; la tête (11) sert de butée axiale.The articulation of the cable (l) on the pivot (2) is effected by means of a pad (3) adjusted on the cylindrical part (10); the head (11) serves as an axial stop.
Ce coussinet '(3) a la forme d'une poulie à gorge unique dont un secteur angulaire est évidê pour permettre un montage radial sur le pivot (2) .This bearing '(3) has the shape of a pulley with a single groove, an angular sector of which is hollowed out to allow radial mounting on the pivot (2).
Une boucle (8) formée par l'extrémité du cable s'accroche dans la gorge et y est retenue par un sertissage (12) .A loop (8) formed by the end of the cable hooks into the groove and is retained there by a crimp (12).
Un rayonnage (14) d'un flan du coussinet (3) permet d'admettre un désalignement du cable (1) par rapport à la gorge du coussinet (3) . Un aimant non représenté placé à proximité, récupère les produits de l'usure de l'articulation et évite ainsi leur circulation dans l'organisme.A shelving (14) of a blank of the pad (3) allows a misalignment of the cable (1) relative to the groove of the pad (3). A not shown magnet placed nearby, collects the products of wear and tear from the joint and thus prevents their circulation in the body.
Un tube fileté (6) est vissé par le bas, dans un tunnel tibial débouchant dans la surface d'implantation du ligament naturel et assure le guidage du cable (1) ainsi qu'un bon accrochage osseux.A threaded tube (6) is screwed from below, in a tibial tunnel opening into the implantation surface of the natural ligament and ensures the guidance of the cable (1) as well as good bone attachment.
Un tube protecteur (4) dont une extrémité est courbée et bisautée est placé dans le tunnel tibial et dans le tube (6) par le haut en même temps que le cable (1) sur lequel il est enfilé. Il assure lors de flexion du genou un enroulement régulier du cable (1) autour de la courbure (13) sans risque d'usure de l'os. L'utilisation d'un cable métallique permet de sertir sur l'extrémité un embout taraudé ou fileté (5).A protective tube (4), one end of which is curved and beveled, is placed in the tibial tunnel and in the tube (6) from above at the same time as the cable (1) on which it is threaded. It ensures during flexion of the knee a regular winding of the cable (1) around the curvature (13) without risk of bone wear. The use of a metal cable makes it possible to crimp a threaded or threaded end piece (5) on the end.
La longueur du ligament est facilement ajustée à l'aide de la vis (7) vissée dans l'embout (5) et prenant appui sur la face inférieure du tube (6) .The length of the ligament is easily adjusted using the screw (7) screwed into the tip (5) and bearing on the underside of the tube (6).
La vis de réglage (7) comporte une zone de faible section (9) qui doit, lors d'un choc très violent, casser avant l'os et avant le cable. Cette vis étant à fleur de peau, elle est facilement remplaçable.The adjusting screw (7) has a small section area (9) which must, during a very violent impact, break before the bone and before the cable. This screw is flush with the skin, it is easily replaceable.
La pose de cette prothèse n'est pas plus traumatisante que celle de prothèses existantes. Le travail du chirrurgien est facilité par la possibilité de corriger la longueur du ligament lors de la pose, ou après une période d'utilisation. L'attache fémorale détache bien le cable du condyle ce qui élimine les problèmes d'interférence. L'utilisation de matériaux métalliques à hautes performances permettra d'avoir des durées de vie importantes et laisse présager de bons résultats quand à la tolérance biologique et au vieillissement en milieu synovial.The placement of this prosthesis is no more traumatic than that of existing prostheses. The work of the surgeon is facilitated by the possibility of correcting the length of the ligament during installation, or after a period of use. The femoral attachment detaches the cable from the condyle well which eliminates interference problems. The use of high performance metallic materials will allow long lifetimes and suggests good results when it comes to biological tolerance and aging in synovial medium.
Cette prothèse est particulièrement adaptée aux sportifs de haut niveau victimes d'une rupture de ligament croisé et devant reprendre rapidement leurs activités. This prosthesis is particularly suitable for high-level sportsmen victims of a cruciate ligament rupture and having to quickly resume their activities.
