Abstract

La prothèse de disque intervertébral (2) comprend un coussin compressible (1 4) comportant un corps (22) réalisé dans un matériau, et un liquide (20) apte à venir en contact avec le corps (22). Le liquide et le matériau sont tels que le liquide ne mouille pas le corps (22).

Description

"PROTHESE DE DISQUE INTERVERTÉBRAL A ENCEINTE DE LIQUIDE".
L'invention concerne les prothèses de disque intervertébral.
On connaît, par exemple du document EP-0 277 282, une prothèse de disque intervertébral destinée à
5 remplacer un disque intervertébral. Elle comporte deux plateaux aptes à venir en appui contre les plateaux vertébraux des vertèbres adjacentes au disque à
remplacer, et un cousin interposé entre les plateaux. Le coussin comporte un corps compressible et une enceinte 10 renfermant un liquide. Cette prothèse a pour inconvénient que le corps compressible est susceptible de s'user, modifiant ainsi à terme le comportement mécanique de la prothèse. De plus, son frottement contre les plateaux provoque l'érosion de particules pouvant 15 migrer dans le corps du patient.
Un but de l'invention est de fournir une prothèse dont le comportement mécanique soit identique sur une longue période de temps, et réduisant les risques de libération de particules dans le corps du patient.
20 En vue de la réalisation de ce but, on prévoit selon l'invention une prothèse de disque intervertébral comprenant un coussin compressible comportant un corps réalisé dans un matériau, et un liquide apte à venir en contact avec le corps, dans laquelle le liquide et le 25 matériau sont tels que le liquide ne mouille pas le corps.
Sachant que le liquide ne mouille pas le corps, la mise en contact forcée du liquide avec le corps requiert une certaine énergie. Cette énergie est restituée en 30 intégralité lorsqu'on permet au liquide de se séparer à
nouveau du corps. On produit ainsi une sorte d'effet ressort. Cet effet est d'autant plus important que la WO 00/35386 PCT/FR99/030?4
2 surface de contact du liquide avec le corps est grande.
La prothèse peut donc encaisser des efforts très importants, en se déformant en compression ou en flexion, puis produire la déformation inverse en 5 restituant l'énergie emmagasinée. Une telle prothèse peut stocker dans un petit volume une quantité d'énergie considérable. En outre, le mouvement du liquide au contact du corps ne génère aucune usure . la prothèse est donc susceptible de présenter le même comportement 10 mécanique sur une période de temps très longue. De plus, l'absence de frottement entre des pièces solides fait pratiquement disparaS.tre tout risque de libération de particules dans le corps.
L'effet ressort sera très élevé en présence d'un 15 corps poreux même de volume très réduit.
Si l'on prévoit que le corps présente des cavités communiquant entre elles suivant des réseaux très longs, le chemin à parcourir par le liquide lors de l'entrée et de la sortie est particulièrement élevé. I1 s'ensuit que 20 le liquide dissipe une partie de l'énergie par sa seule circulation dans le corps. Dès lors, l'ensemble peut constituer un amortisseur partiel. La combinaison de l'effet ressort avec l'effet amortisseur entraîne alors que pour la prothèse, la courbe représentant l'effort en 25 compression en fonction de la variation de longueur de la prothèse suivant son axe principal a une forme en hystérésis, tout comme un disque intervertébral naturel sain. On approche donc de près le comportement mécanique d'un véritable disque.
30 Avantageusement, la prothèse comporte deux plateaux s'étendant de part et d'autre du coussin, le corps étant fixé à au plus un des plateaux.
D'autres caractéristiques et avantages de l'invention apparaîtront encore dans la description

- la figure 2 est la courbe montrant la variation de la force de compression appliquée à la prothèse en fonction de l'évolution de sa hauteur suivant son axe : et - la figure 3 est une vue en perspective de la prothèse de la figure 1.
En référence aux figures 1 et 3, la prothèse 2 comprend deux plateaux 4 ayant en plan une forme générale circulaire ou bien de préférence une forme en haricot à hile postérieur. Les deux plateaux sont plats 15 et s' étendent en vis-à-vis parallèlement l' un à l' autre en étant centrés sur un axe principal 9 de la prothèse perpendiculaire aux plateaux.
Chaque plateau 4 comporte deux pattes 6 s'étendant en saillie d'une face externe 8 du plateau 4 20 perpendiculairement au plan du plateau. Chaque patte 6 présente un orifice 10 la traversant de part en part en direction du centre du plateau et, sur une face de la patte 6 opposée au plateau 4, une empreinte 12 de forme sphérique. Les orifices 10 permettent la réception d'une 25 vis à os 11 ayant une tête dont une face inférieure a une forme sphérique mâle coopérant avec l'empreinte femelle 12 de la patte 6 pour permettre une libre orientation de la vis par rapport à la patte associée.
Sur la figure 1, les deux pattes 6 de chaque plateau ont 30 été ramenées dans le même plan de coupe, ce qui n'est pas le cas en réalité, comme le montre la figure 3.
Pour réaliser un ancrage à court terme de la prothèse de disque 2 dans la colonne, on pourra ancrer
4 les vis 11 dans le spondyle des vertèbres adjacentes au disque à remplacer.
Toutefois, on pourra prévoir un ancrage dit à long terme où, en outre, les surfaces 8 des plateaux 4 en
5 contact avec les vertèbres adjacentes sont recouvertes d'hydroxyapatite, ou de toute autre substance connue en soi pouvant stimuler la croissance osseuse. Avant recouvrement, lesdites. surfaces 8 pourront étre traitées pour obtenir un état de surface plus ou moins poreux, 10 présentant des points d'ancrage pour le tissu osseux, pour assurer une meilleure interface avec ledit tissu osseux.
La prothèse présente un coussin 14 interposé entre les plateaux. Ce coussin comporte un soufflet 16. I1 a 15 une forme symétrique de révolution autour de l'axe 9. Sa paroi présente de profil des ondulations permettant de faire varier la longueur du soufflet 16 suivant la direction axiale 9, sans que varie sensiblement la superficie de sa section transversalement à l' axe 9. En 20 l'espèce, ce soufflet, de même que les plateaux 4, est réalisé en titane ou alliage de titane, de sorte qu'il présente une certaine rigidité axiale et forme un ressort de compression. I1 peut également être déformé
suivant une direction perpendiculaire à l'axe 9 ou subir 25 une torsion autour de l'axe 9 ou d'un axe quelconque perpendiculaire à celui-ci.
Le soufflet 16 présente à ses deux extrémités axiales des bords collés à des bords respectifs des plateaux 4 s'étendant, par exemple mais de façon non 30 illustrée, en saillie d'une face interne 18 des plateaux. Le collage est réalisé de façon étanche de sorte que le soufflet 16 définit avec les deux plateaux 4 une enceinte étanche à volume variable.
6 PCT/FR99/03074 Le soufflet 16 présente, par exemple et de façon non illustrée, dix convolutions, soit huit crêtes externes en plus des deux crêtes de fixation aux plateaux 4. I1 a ici un diamètre externe d'environ 30 mm 5 et un diamètre interne d'environ 17 mm. Sa hauteur, lorsque la prothèse est hors charge, vaut 10 mm. La paroi du soufflet peut être réalisée au moyen d'une, deux ou trois feuilles chacune de 0,1 mm d'épaisseur et dont la somme des épaisseurs forme l'épaisseur de la 10 paroi. Le soufflet a ici en propre une raideur d'environ 1, 6 N/mm.
L'enceinte délimitée par le soufflet 16 et les deux plateaux 4 est remplie d'un liquide 20. Le coussin 14 comporte un corps 22 qui est ici ancré à la face interne 15 plane 18 de l'un des deux plateaux, par exemple le plateau infërieur 4 sur la figure 1. A cette fin, un relief 24 venu du plateau s'étend dans le corps. La forme du corps peut par exemple être cylindrique d'axe 9. Le corps sera par exemple suffisamment étroit 20 perpendiculairement à l'axe 9 pour ne jamais venir en contact avec le soufflet lors de déformations de la prothèse. De même, un espace libre suffisant sera ménagé
entre l'extrémité libre, ici supérieure, du corps 22 et le plateau opposé pour qu'ils ne viennent jamais en 25 contact mutuel. Le corps 22 est environné par le liquide apte à venir en contact avec lui.
Le liquide 20 et le matériau du corps 22 seront de préférence biocompatibles. Ils sont choisis de sorte que le liquide soit non mouillant à l'égard du corps, c'est-30 à-dire qu'en l'absence de sollicitation à cette fin il tende à demeurer hors de contact du corps. Le liquide sera par exemple de l'eau et le matériau du corps un matériau biocompatible tel que du titane ou un alliage de titane. Ce matériau sera de préférence poreux pour offrir une grande surface de contact avec le liquide. De plus, on fera en sorte que les cavités du corps constituant ses pores communiquent entre elles suivant des réseaux assez longs afin de fournir un effet 5 amortisseur en plus de l'effet ressort. Sur la figure 1, les pores ou cavités 26 du corps 22 ont été illustrés de façon schématique pour plus de clarté. I1 va de soi que ces pores sont invisibles à l'échelle de la figure 1 et infiniment plus nombreux que ceux illustrés. Ainsi, la 10 hauteur h étant mesurée de l'un à l'autre des plateaux au niveau de l'axe 9, la courbe illustrant sur la figure 2 la variation de la compression F de la prothèse suivant son axe 9 en fonction de sa variation, négative, de hauteur ~h, aura une forme en hystérésis. Ainsi, la 15 courbe Ca indiquant l'évolution de la force F lorsque celle-ci augmente est tout entière au-dessus de la courbe Cd illustrant la décroissance de la force F.
Cette forme est due à la combinaison de l' effet ressort et de l'effet amortisseur.
20 On pourra prévoir une poche de gaz à l'intérieur de l'enceinte de liquide.
La prothèse selon l'invention est particulièrement adaptée à la zone lombaire du rachis.
Bien entendu, on pourra apporter à l'invention de 25 nombreuses modifications sans sortir du cadre de celle ci. Le corps 22 pourra être sans ancrage à l'égard des plateaux. I1 sera ainsi libre de se déplacer spontanément à l'égard de chacun d'eux. La prothèse pourra alors être agencée pour qu'en toute position et 30 tout état de sollicitation de la prothèse, le corps 22 soit en contact avec au plus l'un des plateaux.
Le corps 22 pourra avoir une forme en ellipsoïde.
