Abstract

The invention relates to a prosthesis for the anterior cruciate ligament which, while maintaining the isometry of functioning of the knee, avoids the associated osseous problems. It consists of a flexible cable (1), one end of which is articulated around a pin (2) implanted in the outer condyle. The other end is fixed to the tibia by means of a device (5, 6 and 7) making it possible to adjust the length. This prosthesis is designed in particular for sports persons who have torn the anterior cruciate ligament and who must resume their activities quickly.

Description

La présente invention est destinée à remplacer le ligament croisé antérieur (LCA) naturel du genou humain dont la défaillance provoque un handicap important et peut générer de l'arthrose. The present invention is intended to replace the natural anterior cruciate ligament (ACL) of the human knee, the failure of which causes significant handicap and can generate osteoarthritis.

Il existe actuellement deux voies dans la chirurgie du LCA
- Les auto-plasties : le ligament est remplacé par
une partie d'un des tendons du genou. Si cette
technique ne pose pas de problème de biocompatibi
lité, il demeure des risques d'étirement et une
fragilisation du tendon sur lequel est prélevé
l'implant. There are currently two pathways in ACL surgery
- Self-plasty: the ligament is replaced by
part of one of the knee tendons. If this
technique does not pose a biocompatibi problem
However, there are still risks of stretching and
weakening of the tendon from which is removed
the implant.

- Les ligaments prothétiques : ils sont réalisés à
l'aide de fibres fléxibles synthétiques. Si la
fixation sur le tibia ne pose pas de gros
problèmes,la fixation fémorale plus délicate,
s'oriente sur deux voies
- 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.- Prosthetic ligaments: they are made at
using synthetic flexible fibers. If the
fixation on the shin does not pose large
problems, more delicate femoral fixation,
is moving in two directions
- in a condylar transosseous tunnel, which
respects isometry but poses problems
tunnel wear and interference with the
edge of condyle.

- en "over the top" où l'isométrie n'est plus
respectée ce qui peut donner des limitations en
flexion ou en extension.- in "over the top" where the isometry is no longer
respected which can give limitations in
flexion or extension.

Ces ligaments peuvent poser des problèmes de
tolérance; de plus, la tenue au vieillissement en
milieu synovial est mal connue.These ligaments can cause problems
tolerance; moreover, the aging resistance in
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 comporte une boucle qui vient s'articuler autour d'un pivot implanté dans le condyle externe. Cette articulation permet d'éviter l'abrasion du condyle et de conserver l'isométrie de fonctionnement du genou. The femoral end of the ligament has a loop which is articulated around a pivot implanted in the external condyle. This joint makes it possible to avoid abrasion of the condyle and to keep the knee functioning isometric.

L'extrémité tibiale comporte un système vis-écrou qui permet de régler la longueur du ligament.  The tibial end has a screw-nut system that adjusts the length of the ligament.

L'utilisation de matériaux métalliques permet de minimiser les risques d'allergie. 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 accompanying drawings, in which
- Figures 1 and 2 show, in sections
profile and front view, one
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 sections
partial profile and front view respectively,
a bent knee fitted 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 externe en un point proche du centre de l'implantation naturelle du ligament croisé antérieur, 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 external condyle at a point close to the center of the natural implantation of the anterior 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 (1) 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 (1) 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 évidé pour permettre un montage radial sur le pivot (2). This bearing (3) has the shape of a single-grooved pulley, 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).  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).

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 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. A protective tube (4), one end of which is curved and bevelled, 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.

L'utilisation d'un cable métallique permet de sertir sur l'extrémité un embout taraudé ou fileté (5).The use of a metal cable makes it possible to crimp on the end a threaded or threaded end (5).

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 end piece (5) and resting 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 trés violent, casser avant l'os et avant le cable. Cette vis étant à fleur de peau, elle est facilement remplaçable. The adjustment screw (7) has a zone of small section (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 antérieur et devant reprendre rapidement leurs activités.  This prosthesis is particularly suitable for high-level athletes who are victims of an anterior cruciate ligament rupture and who need to quickly resume their activities.
