Cage intervertébrale apte à être interposée entre les deux corps vertébraux (Cv1, Cv2) de deux vertèbres consécutives, caractérisée par le fait qu'elle est constituée - d'une plaque courbe (10) comportant une première et une seconde branches (12, 14) aptes à venir au contact respectivement des deux corps vertébraux, et une paroi de liaison (16) relativement élastique reliant les deux branches sensiblement en une de leurs extrémités respectives (18, 20), - des premiers moyens (21) pour fixer un point (23) de la première branche (12), dit "premier point", au corps vertébral (Cv1) avec lequel elle est destinée à venir en contact, et - des seconds moyens (22) pour fixer un point (24) de la seconde branche (14), dit "second point", à l'autre des deux corps vertébraux (Cv2) avec lequel elle est destinée à venir en contact.
- 2. Cage intervertébrale selon la revendication 1, caractérisée par le fait que ladite plaque courbe présente sensiblement l'une des deux formes suivantes : en U, en Z, préférentiellement en U.
- 3. Cage intervertébrale selon l'une des revendications 1 et 2, caractérisée par le fait que les moyens (21, 22) pour fixer un point (23, 24) d'au moins l'une des branches (12, 14) au corps vertébral avec lequel elle est destinée à venir en contact sont constitués par : - unè lame (31, 32) ayant une extrémité coupante apte à pénétrer 25 dans un milieu osseux, et - des moyens pour monter ladite lame en rotation par rapport à la branche, de façon qu'elle soit apte à prendre deux positions : une première position dans laquelle ladite lame est entièrement comprise dans le volume délimité par la surface enveloppant 30 extérieurement les deux dites branches (12, 14), et * une seconde position dans laquelle, après sa rotation à partir de la première position, au moins une partie de l'extrémité coupante de ladite lame émerge de ladite surface. 3029770 9
- 4. Cage intervertébrale selon la revendication 3, caractérisée par le fait que les moyens pour monter ladite lame en rotation par rapport à la branche comportent : - une embase cylindrique (34) solidaire de l'extrémité de ladite lame 5 (31, 32) opposée à son extrémité coupante, - un orifice (36) réalisé dans ladite branche (12, 14), ledit orifice ayant une section complémentaire de la section transversale de l'embase cylindrique de façon que ladite embase soit apte à pivoter dans ledit orifice, et 10 - des moyens (35) pour lier ladite embase (34) en rotation avec ladite branche sans possibilité de translation.
- 5. Cage intervertébrale selon la revendication 4, caractérisée par le fait que lesdits moyens (35) pour lier ladite embase (34) en rotation avec ladite branche comportent au moins : 15 - une gorge circulaire (38) réalisée dans la paroi latérale de ladite embase (34), - au moins une percée traversante (39, 40) réalisée dans ladite branche selon une direction sensiblement orthogonale à l'axe du dit orifice (36), cette percée étant réalisée de façon qu'elle intercepte ledit orifice (36) 20 et que son axe passe sensiblement par ladite gorge (38) quand ladite embase (34) est enfichée dans ledit orifice, et - une broche (42) enfichée dans ladite percée traversante en passant par ladite gorge (38).
- 6. Cage intervertébrale selon l'une des revendications 4 et 5, caractérisée par le fait que, ladite plaque courbe (10) présentant une forme sensiblement en U, l'orifice (36) est réalisé dans ladite branche (12, 14) de façon qu'il débouche sur la tranche (12-1, 14-1) de cette branche correspondant à une extrémité libre du U.
- 7. Cage intervertébrale selon l'une des revendications précédentes, 30 caractérisée par le fait qu'elle comporte des moyens de butée (50) pour limiter le rapprochement des deux branches (12, 14) l'une par rapport à l'autre. 3029770 10
- 8. Cage intervertébrale selon la revendication 7, caractérisée par le fait que les moyens de butée (50) quand ladite plaque courbe présente une forme sensiblement en U, sont constitués par une butée (51) solidaire sensiblement de l'extrémité libre d'une des deux branches (12, 14) et une 5 contre butée (52) solidaire de l'autre branche (14, 12), ladite butée et ladite contre butée étant agencées de façon que, lorsque les extrémités libres respectivement des deux branches se rapprochent l'une de l'autre, la butée et la contre butée soient aptes à venir au contact l'une de l'autre.
- 9. Cage intervertébrale selon la revendication 8, caractérisée par le 10 fait que la butée (51) est constituée par un bossage (54) réalisé sur la branche et que la contre butée (52) est constituée par l'autre branche qui est réalisée de façon que son extrémité libre (56) soit sensiblement au moins au même niveau, pris dans un plan sensiblement perpendiculaire au plan général des branches, que ledit bossage. 15
- 10. Cage intervertébrale selon l'une des revendications précédentes, caractérisée par le fait qu'au moins l'une des deux branches comporte une cavité borgne (60) ouverte sur sa face qui est apte à venir en contact avec un corps vertébral.
- 11. Cage intervertébrale selon l'une des revendications précédentes, 20 caractérisée par le fait que ladite paroi de liaison (16) est amincie pour lui conférer sa relative élasticité.
- 12. Cage intervertébrale selon l'une des revendications précédentes quand elle dépend de la revendication 4, caractérisée par le fait que ladite embase (34) comporte un trou axial (70) à section transversale polygonale. 25
