Description

La présente invention se rapporte à une cage intersomatique, notamment du type TLIF (Transforaminal Lumbar Interbody Fusion). The present invention relates to an intersomatic cage, in particular of the TLIF type (Transforaminal Lumbar Interbody Fusion).

La technique d'insertion transforaminale d'une cage lombaire de ce genre consiste à réaliser une incision dans le dos du patient, à disséquer du muscle et des articulations pour avoir accès à l'espace entre les vertèbres, à retirer le disque de la colonne d'entre deux vertèbres, puis à insérer la cage à la place du disque. The transforaminal insertion technique of a lumbar cage of this kind involves making an incision in the back of the patient, dissecting muscle and joints to gain access to the space between the vertebrae, removing the disc from the spine. between two vertebrae, then insert the cage instead of the disc.

Pour ce faire, i1 est nécessaire de contourner les éléments articulaires. Ce contournement nécessite que le praticien fasse subir à la cage lors de son insertion dans l'espace discal un mouvement en arc de cercle. To do this, it is necessary to circumvent the articular elements. This circumvention requires the practitioner to subject the cage during its insertion into the disc space a movement in an arc.

La présente invention se rapporte également à un assemblage constitué d'une cage intersomatique, notamment du genre TLIF, et d'un dispositif de mise en place de la cage dans l'espace discal entre deux vertèbres. The present invention also relates to an assembly consisting of an intersomatic cage, in particular of the TLIF genus, and a device for positioning the cage in the disc space between two vertebrae.

Il est déjà connu dans l'art antérieur des assemblages de ce genre comportant une cage et une tige, la cage comportant des moyens destinés à relier de manière temporaire la tige à 1a cage pour permettre l'insertion de celle-ci dans l'espace discal. Dans ces assemblages de l'art antérieur, le praticien ou chirurgien, une fois la tige reliée à la cage, pousse celle-ci entre les vertèbres puis fait subir à la cage, toujours à l'aide de la tige, une rotation pour la positionner dans l'espace discal entre les vertèbres. Cet assemblage de l'art antérieur ne permet pas d'assurer au chirurgien une grande précision du mouvement en arc de cercle et, en particulier, l'axe suivant lequel le chirurgien agit sur la tige d'insertion varie au cours de la rotation de la cage, ce qui n'est pas bon pour la précision de l'insertion. Il en résulte qu'il est également nécessaire pour pouvoir insérer ces cages de réaliser une incision d'assez grande taille et de disséquer une assez grande quantité de muscle et/ou d'articulation au voisinage de l'espace discal, alors même qu'on souhaiterait avoir à disposition un assemblage qui permette de limiter autant que possible, d'une part, la taille de l'incision réalisée et la quantité d'articulation et/ou de muscle à éliminer et, d'autre part, donner au chirurgien le maximum de facilité pour manipuler la cage en vue de l'insérer entre les vertèbres. It is already known in the prior art assemblies of this kind comprising a cage and a rod, the cage comprising means for temporarily connecting the rod to the cage to allow the insertion thereof into space disc. In these assemblies of the prior art, the practitioner or surgeon, once the rod connected to the cage, pushes it between the vertebrae and then makes the cage, always using the rod, a rotation for the position in the disc space between the vertebrae. This assembly of the prior art does not ensure the surgeon high precision of the arcuate movement and, in particular, the axis along which the surgeon acts on the insertion rod varies during the rotation of the the cage, which is not good for the precision of insertion. As a result, it is also necessary to be able to insert these cages to make an incision of rather large size and to dissect a fairly large amount of muscle and / or joint in the vicinity of the disc space, even though we would like to have available an assembly that allows to limit as much as possible, on the one hand, the size of the incision made and the amount of joint and / or muscle to be eliminated and, on the other hand, to give the surgeon the easiest way to manipulate the cage to insert it between the vertebrae.

La présente invention vise ainsi à surmonter les inconvénients des assemblages de l'art antérieur en proposant un assemblage du genre mentionné ci-dessus, qui permet d'effectuer l'insertion de la cage en n'ayant à réaliser qu'une incision de taille très petite, notamment dans le dos du patient dans le cas d'une technique TLIF, et à n'éliminer aussi peu de muscle et/ou d'articulations que possible au voisinage de l'espace discal, et qui donne dans le même temps au chirurgien une grande facilité pour réaliser le mouvement d'insertion, notamment la rotation de la cage suivant un arc de cercle, pour son positionnement final entre les deux vertèbres. The present invention thus aims to overcome the disadvantages of the prior art assemblies by proposing an assembly of the kind mentioned above, which allows the insertion of the cage by having to make only a large incision very small, especially in the back of the patient in the case of a TLIF technique, and to eliminate as little muscle and / or joints as possible in the vicinity of the disc space, and which gives at the same time the surgeon great ease to perform the insertion movement, including the rotation of the cage following a circular arc, for its final positioning between the two vertebrae.

Suivant l'invention, un assemblage, comportant une cage intersomatique destinée à être insérée entre deux vertèbres, notamment par la technique TLIF, en vue de consolider par fusion l'espace entre les deux vertèbres et un instrument d'insertion destiné à être relié à la cage pour l'insertion de celle-ci, des premiers moyens de solidarisation en rotation de l'instrument d'insertion à la cage dans une première position relative de la cage par rapport à l'instrument étant prévus, est caractérisé en ce qu'il est prévu des deuxièmes moyens de solidarisation en rotation de l'instrument d'insertion à la cage dans une deuxième position relative de la cage par rapport à l'instrument, la cage entre la première position relative et la deuxième position relative ayant subi une rotation par rapport à l'instrument d'insertion, notamment d'un angle compris entre 20 et 50°, notamment d'environ 30°. According to the invention, an assembly comprising an intersomatic cage intended to be inserted between two vertebrae, in particular by the TLIF technique, in order to consolidate by fusion the space between the two vertebrae and an insertion instrument intended to be connected to the cage for the insertion thereof, the first means for securing the insertion instrument to the cage in a first relative position of the cage relative to the instrument being provided, is characterized in that there are provided second means for securing the insertion instrument to the cage in a second relative position of the cage relative to the instrument, the cage between the first relative position and the second relative position having undergone a rotation relative to the insertion instrument, in particular at an angle of between 20 and 50 °, in particular about 30 °.

En prévoyant deux positions différentes de solidarisation en rotation de la cage par rapport à l'instrument, on facilite grandement le travail du chirurgien. En effet, la première position donne au chirurgien une grande facilité pour un premier mouvement d'insertion par le côté de la cage. Ensuite, avant de réaliser un mouvement en arc de cercle de la cage pour son positionnement final entre les deux vertèbres, le chirurgien fait passer l'assemblage dans la deuxième position relative qui lui donne une grande facilité pour réaliser ce deuxième mouvement de rotation. By providing two different positions for rotationally securing the cage relative to the instrument, it greatly facilitates the work of the surgeon. Indeed, the first position gives the surgeon great ease for a first insertion movement by the side of the cage. Then, before making an arcuate movement of the cage for its final positioning between the two vertebrae, the surgeon passes the assembly in the second relative position which gives it a great facility to achieve this second rotational movement.

Suivant un-mode de réalisation préféré de l'invention, le dispositif d'insertion comporte une tige,, les premier et deuxième moyens de solidarisation comportent respectivement des premier et deuxième trous formés dans la cage, une extrémité de la tige étant reçue dans le premier trou lorsque l'assemblage se trouve dans la première position relative, et une extrémité de la tige, notamment ladite une extrémité, étant reçue dans le deuxième trou lorsque l'assemblage se trouve dans la deuxième position relative. According to a preferred embodiment of the invention, the insertion device comprises a rod, the first and second securing means respectively comprise first and second holes formed in the cage, one end of the rod being received in the first hole when the assembly is in the first relative position, and an end of the rod, in particular said one end, being received in the second hole when the assembly is in the second relative position.

Suivant un mode de réalisation préféré de l'invention, la solidarisation de la tige dans la première ou la deuxième position comporte un vissage, et notamment la tige comporte une partie filetée qui coopère avec une partie taraudée de la cage. According to a preferred embodiment of the invention, the securing of the rod in the first or second position comprises a screwing, and in particular the rod comprises a threaded portion which cooperates with a threaded portion of the cage.

Suivant un mode de réalisation particulièrement préféré de l'invention, il est disposé dans la cage une rotule, notamment cylindrique, qui peut pivoter par rapport à la cage et qui est percée d'un trou traversant, le trou traversant pouvant déboucher, en fonction, de la rotation relative de la rotule par rapport à la cage, d'une part à l'extérieur de la cage et d'autre part en face d'un des trous destinés à recevoir une extrémité de la tige respectivement dans les première et deuxième positions. According to a particularly preferred embodiment of the invention, there is disposed in the cage a ball, particularly cylindrical, which is pivotable relative to the cage and which is pierced with a through hole, the through hole being able to open, depending , the relative rotation of the ball with respect to the cage, firstly outside the cage and secondly in front of one of the holes for receiving an end of the rod respectively in the first and second positions.

Ainsi, la rotule permet de guider la tige pour l'introduction d'une extrémité dans l'un des trous des deux positions et, d'autre part, facilite le passage de la tige d'une des positions dans l'autre position. Thus, the ball joint makes it possible to guide the rod for the introduction of an end into one of the holes of the two positions and, on the other hand, facilitates the passage of the rod from one of the positions to the other position.

Suivant un mode de réalisation préféré de l'invention, le trou traversant de la rotule est taraudé et la tige comporte une partie filetée destinée à être vissée au taraudage du trou traversant de la rotule. Ainsi, le chirurgien, lorsqu'il insère la tige dans la cage, visse la tige dans le trou traversant jusqu'à ce que la partie d'extrémité de la tige pénètre dans l'un des trous pour ainsi atteindre une des première ou deuxième positions. Lorsqu'il veut passer dans l'autre position, il dévisse légèrement la tige de la rotule jusqu'à rétracter la partie d'extrémité de la tige hors du premier trou, puis fait pivoter la rotule pour amener le trou traversant en face du deuxième trou, et de nouveau visse la tige pour faire pénétrer son extrémité dans le deuxième trou pour ainsi se trouver dans la deuxième position. On a ainsi un système particulièrement simple pour le chirurgien. According to a preferred embodiment of the invention, the through hole of the ball joint is threaded and the rod comprises a threaded portion intended to be screwed to the thread of the through hole of the ball joint. Thus, the surgeon, when inserting the rod into the cage, screws the rod into the through hole until the end portion of the rod enters one of the holes to thereby reach one of the first or second positions. When he wants to go into the other position, he slightly unscrews the rod of the ball until retracting the end portion of the rod out of the first hole, then rotates the ball to bring the through hole in front of the second hole, and again screw the rod to penetrate its end in the second hole and thus be in the second position. There is thus a particularly simple system for the surgeon.

De préférence, la partie d'extrémité de la tige destinée à pénétrer dans l'un des premier ou deuxième trous n'est pas filetée et est à la suite d'une partie filetée de la tige. Preferably, the end portion of the rod intended to penetrate into one of the first or second holes is not threaded and is following a threaded part of the rod.

Suivant un mode de réalisation préféré de l'invention, la cage est une cage TLIF, et notamment a une forme incurvée imitant la courbure naturelle des vertèbres. According to a preferred embodiment of the invention, the cage is a TLIF cage, and in particular has a curved shape imitating the natural curvature of the vertebrae.

Suivant un mode de réalisation préféré de l'invention, dans une des deux positions, la tige est sensiblement parallèle à l'axe sagittal de la cage. According to a preferred embodiment of the invention, in one of the two positions, the rod is substantially parallel to the sagittal axis of the cage.

La présente invention se rapporte également à une cage intersomatique, notamment du type TLIF, destinée à être insérée entre deux vertèbres, notamment par la technique TLIF, en vue de consolider par fusion l'espace entre les deux vertèbres et destinée à être reliée à un instrument d'insertion pour son insertion, des premiers moyens de solidarisation en rotation de l'instrument d'insertion à la cage dans une première position relative de la cage par rapport à l'instrument étant prévus, est caractérisée en ce qu'il est prévu des deuxièmes moyens de solidarisation en rotation de l'instrument d'insertion à la cage dans une deuxième position relative de la cage par rapport à l'instrument, la cage entre la première position relative et la deuxième position relative ayant subi une rotation par rapport à l'instrument d'insertion, notamment d'un angle compris entre 20 et 50°, notamment d'environ 30°. The present invention also relates to an intersomatic cage, in particular of the TLIF type, intended to be inserted between two vertebrae, in particular by the TLIF technique, in order to consolidate by fusion the space between the two vertebrae and intended to be connected to a inserting instrument for its insertion, the first means for securing in rotation the insertion instrument to the cage in a first relative position of the cage relative to the instrument being provided, is characterized in that it is provided second means for securing the insertion instrument to the cage in a second relative position of the cage relative to the instrument, the cage between the first relative position and the second relative position rotated by relative to the insertion instrument, especially at an angle of between 20 and 50 °, in particular about 30 °.

A titre d'exemple, on décrit maintenant un mode de réalisation de l'invention en se reportant aux dessins dans lesquels : la Figure 1 est une vue en perspective de dessus d'une cage suivant l'invention ; la Figure 2 est une vue de dessous de la cage de la Figure 1 ; la Figure 3 est une vue en coupe suivant la ligne A-A de la Figure 1, à plus grande échelle ; la Figure 4 représente en perspective la cage des Figures 1 à 3 et une tige d'insertion destinée à coopérer avec la cage pour insérer cette dernière entre deux vertèbres, une partie de la cage étant arrachée suivant la ligne A-A de la Figure 1 et l'ouverture 5 de la cage étant emplie d'un matériau formant substitut osseux ; la Figure 5 est une vue en coupe d'un assemblage constitué d'une cage suivant les Figures 1 à 3 et de la tige de la Figure 4 dans la première position d'insertion ; et la Figure 6 est une vue identique à la Figure 5, dans la deuxième position d'insertion. A Aux Figures 1 à 3, il est représenté une cage intersomatique TLIF. Cette cage est destinée à être insérée entre deux vertèbres en effectuant un premier mouvement de poussée par le côté, puis un mouvement de contournement constitué d'une rotation sur un arc de cercle. La cage comporte une paroi 1 postérieure incurvée et une parôi 2 antérieure incurvée sensiblement parallèle à la paroi 1 postérieure. Les deux parois 1 et 2 postérieure et antérieure sont réunies par une paroi 3 proximale et se rejoignent par une paroi 4 distale convexe. Les quatre parois postérieure, antérieure, distale et proximale délimitent entre elles un espace 5 ouvert destiné à recevoir du greffon ou du substitut osseux pour aider à la repousse par fusion osseuse une fois la cage insérée entre les deux vertèbres. On définit le côté supérieur de la cage comme étant le côté que l'on voit de dessus à la Figure 1, le côté inférieur de la cage étant de l'autre côté. By way of example, an embodiment of the invention will now be described with reference to the drawings in which: FIG. 1 is a perspective view from above of a cage according to the invention; Figure 2 is a bottom view of the cage of Figure 1; Figure 3 is a sectional view along the line A-A of Figure 1, on a larger scale; 4 shows in perspective the cage of FIGS. 1 to 3 and an insertion rod intended to cooperate with the cage to insert the latter between two vertebrae, a portion of the cage being torn off along the line AA of FIG. opening 5 of the cage being filled with a bone substitute material; Figure 5 is a sectional view of an assembly consisting of a cage according to Figures 1 to 3 and the rod of Figure 4 in the first insertion position; and Figure 6 is a view identical to Figure 5, in the second insertion position. In Figures 1 to 3, there is shown a TLIF interbody cage. This cage is intended to be inserted between two vertebrae by performing a first pushing movement by the side, then a bypass movement consisting of a rotation on a circular arc. The cage has a curved posterior wall 1 and a curved front wall 2 substantially parallel to the posterior wall 1. The two walls 1 and 2 posterior and anterior are joined by a proximal wall 3 and meet by a convex distal wall 4. The four posterior, anterior, distal and proximal walls delimit between them an open space for receiving graft or bone substitute to assist bone regrowth once the cage is inserted between the two vertebrae. The upper side of the cage is defined as the side seen from above in Figure 1, the lower side of the cage being on the other side.

Il est formé dans la paroi 3 proximale de la cage une cavité 6 cylindrique circulaire d'axe vertical. Cette cavité 6 débouche à l'extérieur, du côté inférieur de la cage, comme on le voit à la Figure 2. Dans cette cavité 6 cylindrique, il est inséré une rotule 7 de forme complémentaire cylindrique circulaire de la cavité 6. Cette rotule 7 est insérée dans la cavité 6 par ajustement serré ou par clippage, de manière à être bloquée par la dimension de l'ouverture de la cavité 6 qui est légèrement plus petite que le diamètre de la rotule tandis que l'intérieur de la cavité a une dimension sensiblement identique à celle de la rotule de sorte que celle-ci ne puisse plus sortir de cette cavité, mais cependant puisse pivoter suivant l'axe vertical dans la cavité 6. La rotule 7 comporte un trou traversant s'étendant perpendiculairement à l'axe vertical et qui traverse de part en part diamétralement la rotule 7. Ce trou traversant 16 comporte un taraudage 17 sur sa paroi intérieure. It is formed in the proximal wall 3 of the cage a circular cylindrical cavity 6 of vertical axis. This cavity 6 opens on the outside, on the lower side of the cage, as seen in FIG. 2. In this cylindrical cavity 6, there is inserted a ball 7 of complementary circular cylindrical shape of the cavity 6. This ball 7 is inserted into the cavity 6 by snug fit or by clipping, so as to be blocked by the dimension of the opening of the cavity 6 which is slightly smaller than the diameter of the patella while the interior of the cavity has a dimension substantially identical to that of the ball so that it can not get out of this cavity, but can however pivot along the vertical axis in the cavity 6. The ball 7 has a through hole extending perpendicular to the vertical axis and which crosses diametrically through the ball joint 7. This through hole 16 has a thread 17 on its inner wall.

Une fenêtre 8 est formée dans la paroi 3 entre la cavité 6 cylindrique circulaire et l'extérieur de la cage. Ainsi, cette fenêtre 8 débouche d'une part dans la cavité 6 et d'autre part à l'extérieur du côté proximal de la paroi 3. En particulier, cette fenêtre est constituée de deux évidements 19, 20 cylindriques circulaires disposés côte à côte de manière à former un cylindre ayant une section en huit couché. De l'autre côté de la cavité 6 cylindrique verticale par rapport à la fenêtre 8, il est formé dans la paroi 3, entre la rotule et l'espace 5, deux trous cylindriques borgnes 9 et 10. Ces deux trous borgnes 9 et 10 sont de forme cylindrique circulaire. Ils sont disposés de manière à déboucher sensiblement côte à côte dans la cavité 6 en ayant leur axe de cylindre de trou borgne respectif mutuellement inclinés l'un par rapport à l'autre. Chacun des trous 9, 10 se trouvent diamétralement, par rapport à la cavité 6, en face d'un évidement respectif des deux évidements 19, 20. A window 8 is formed in the wall 3 between the circular cylindrical cavity 6 and the outside of the cage. Thus, this window 8 opens on the one hand into the cavity 6 and on the other hand outside the proximal side of the wall 3. In particular, this window consists of two circular cylindrical recesses 19, 20 arranged side by side. to form a cylinder having a recumbent section. On the other side of the vertical cylindrical cavity 6 with respect to the window 8, two blind cylindrical holes 9 and 10 are formed in the wall 3, between the ball and the space 5. These two blind holes 9 and 10 have a circular cylindrical shape. They are arranged to open substantially side by side in the cavity 6 having their respective blind hole cylinder axis mutually inclined relative to each other. Each of the holes 9, 10 are diametrically, with respect to the cavity 6, opposite a respective recess of the two recesses 19, 20.

A la Figure 4, il est décrit une tige d'insertion destinée à permettre l'insertion de la cage des Figures 1 à 3 dans l'espace discal entre deux vertèbres. La tige comporte un tronçon 10 proximal formant manche destiné à être pris par le chirurgien. A la suite de ce tronçon 10 proximal, un tronçon 11 intermédiaire s'étend en étant de plus petit diamètre que le tronçon 10. Enfin, la tige est terminée par un tronçon 12 distal de diamètre plus petit que le tronçon 11 intermédiaire. In Figure 4, there is described an insertion rod for allowing the insertion of the cage of Figures 1 to 3 in the disc space between two vertebrae. The stem has a proximal portion 10 forming a handle to be taken by the surgeon. Following this proximal section, an intermediate section 11 extends to be of smaller diameter than the section 10. Finally, the rod is terminated by a distal section 12 of smaller diameter than the intermediate section 11.

Le tronçon 11 intermédiaire comporte un filetage 18. Le tronçon 12 distal ne comporte pas de filetage. Le filetage du tronçon 11 intermédiaire correspond au taraudage 17 du trou traversant 16 de la rotule 7. Le diamètre du tronçon 12 distal est tel qu'il puisse pénétrer dans les trous 9 et 10 borgnes). En outre, de préférence, la longueur du tronçon 12 correspond à la longueur des trous 9 et 10, c'est-à-dire leur dimension dans la direction de leur axe longitudinal. Cependant, cette caractéristique n'est pas une nécessité et on pourrait également prévoir que le tronçon 12 soit de plus petite longueur que les trous 9 et 10 oblongs ou au contraire d'une longueur un peu plus grande. Cela sera bien compris par la suite au vu du fonctionnement et des fonctions respectives de la tige et des trous. The intermediate section 11 has a thread 18. The distal section 12 has no threading. The threading of the intermediate section 11 corresponds to the thread 17 of the through hole 16 of the ball 7. The diameter of the distal section 12 is such that it can penetrate into the blind holes 9 and 10). In addition, preferably, the length of the section 12 corresponds to the length of the holes 9 and 10, that is to say their dimension in the direction of their longitudinal axis. However, this feature is not a necessity and it could also be provided that the section 12 is shorter in length than the holes 9 and 10 oblong or on the contrary a slightly longer length. This will be understood later in view of the operation and the respective functions of the rod and holes.

Aux Figures 5 et 6, il est représenté la manière dont coopère la tige de la Figure 4 avec la cage des Figures 1 à 3 pour son insertion entre deux vertèbres. Dans la première position représentée à la Figure 5, la tige a été insérée dans l'évidement 19 de la fenêtre 8, le tronçon 11 intermédiaire se vissant dans le taraudage 17 du trou traversant et le tronçon 12 distal se trouvant dans le trou 10 borgne. L'assemblage tige-cage se trouve alors dans la première position d'insertion. Le fait que la partie 12 distale se trouve dans le trou 10 fait que le chirurgien ne peut plus faire pivoter la rotule et donc la tige par rapport à la cage, la partie 12 distale bloquant la rotation de la rotule 7. Dans cette première position, la tige et la cage sont solidaires d'une part en rotation par l'interaction trou borgne 10-partie distale 12 de la tige et d'autre part en translation par le vissage du tronçon 11 au taraudage 17 et au fait que la partie distale 12 bute contre le fond du trou 10 borgne. Dans le même temps, le vissage de la tige fait qu'aucun mouvement de retrait de la tige n'est possible. Ainsi, dans cette première position, la tige et la cage sont solidaires aussi bien en rotation qu'en translation. Dans cette première position, la tige est sensiblement parallèle à la direction sagittale. Elle est, en particulier, perpendiculaire au plan de la surface extérieure de la paroi 3 proximale. In Figures 5 and 6, there is shown how the rod of Figure 4 cooperates with the cage of Figures 1 to 3 for its insertion between two vertebrae. In the first position shown in FIG. 5, the rod has been inserted in the recess 19 of the window 8, the intermediate section 11 being screwed into the tapping 17 of the through hole and the distal section 12 being in the blind hole . The rod-cage assembly is then in the first insertion position. The fact that the distal portion 12 is in the hole 10 causes the surgeon can no longer rotate the patella and thus the rod relative to the cage, the distal portion 12 blocking the rotation of the ball 7. In this first position , the rod and the cage are integral on the one hand in rotation by the blind hole 10-distal part 12 interaction of the rod and on the other hand in translation by the screwing of the section 11 to the tapping 17 and the fact that the part distal 12 abuts the bottom of the blind hole 10. At the same time, the screwing of the rod makes that no movement of withdrawal of the rod is possible. Thus, in this first position, the rod and the cage are secured in rotation as well as in translation. In this first position, the rod is substantially parallel to the sagittal direction. It is, in particular, perpendicular to the plane of the outer surface of the proximal wall 3.

Une fois la tige et la cage solidarisées dans cette première position, le chirurgien peut insérer, après avoir réalisé l'incision appropriée, la cage entre les vertèbres en passant par le côté. Cependant, lors de cette insertion, il doit à un moment donné effectuer une rotation de la cage pour contourner des articulations, muscles et/ou nerfs pour positionner la cage dans sa position finale. Il fait alors passer l'assemblage tige- cage dans une deuxième position relative. Pour ce faire, il dévisse la tige de la cage pour faire en sorte que la partie 12 distale se retire du trou 10 borgne. Une fois, la partie 12 retirée du trou 10, la rotule 7 n'est plus bloquée en. rotation et le chirurgien peut ainsi faire pivoter la tige de manière à ce que le trou traversant de la rotule 7 et la partie 12 distale qui se trouve en son sein soit amené en face du trou 9, décalé par rapport au trou 10, la tige dans le même temps étant passée de l'évidement 19 à l'évidement 20 de la fenêtre 8. Une fois cette rotation réalisée, le chirurgien visse de nouveau la tige à fond jusqu'à ce que la partie 12 proximale pénètre maintenant dans le trou 9, bloquant ainsi toute rotation de la rotule 7 et donc toute rotation relative de la tige par rapport à la cage. Dans cette deuxième position, dans laquelle la tige a été tournée d'un angle à la figure d'environ 35° et qui peut être compris de préférence entre 25 et 50°, la tige et la cage sont solidarisées aussi bien en rotation qu'en translation. Dans cette deuxième position, l'orientation relative de la cage et de la tige est différente de celle dans la première position. Le chirurgien peut alors faire tourner l'ensemble jusqu'à amener la tige dans une position par rapport au patient sensiblement identique à celle dans laquelle elle se trouvait avant qu'il ait fait passer la tige de la première à la deuxième position. Par rotation de la tige, on peut ainsi faire subir la rotation appropriée à la cage pour son positionnement final entre les deux vertèbres. Grâce au système suivant l'invention, on obtient ainsi une insertion très aisée de la cage entre les deux vertèbres et notamment une grande précision dans la quantité de rotation qu'il convient de faire subir à la cage. Une fois la cage positionnée, le chirurgien dévisse la tige complètement jusqu'à la faire sortir de la cage. Once the rod and the cage secured in this first position, the surgeon can insert, after making the appropriate incision, the cage between the vertebrae passing through the side. However, during this insertion, he must at one point rotate the cage to bypass joints, muscles and / or nerves to position the cage in its final position. It then passes the rod-cage assembly in a second relative position. To do this, he unscrews the shaft of the cage to cause the distal portion 12 to withdraw from the blind hole. Once the portion 12 removed from the hole 10, the ball 7 is no longer locked in. rotation and the surgeon can thus rotate the rod so that the hole through the ball 7 and the distal portion 12 located therein is brought in front of the hole 9, offset from the hole 10, the rod at the same time having passed from the recess 19 to the recess 20 of the window 8. Once this rotation is completed, the surgeon screws the rod again until the proximal portion 12 now penetrates the hole 9, thus blocking any rotation of the ball 7 and therefore any relative rotation of the rod relative to the cage. In this second position, in which the rod has been turned by an angle in the figure of about 35 ° and which can be preferably between 25 and 50 °, the rod and the cage are secured in rotation as well as in in translation. In this second position, the relative orientation of the cage and the rod is different from that in the first position. The surgeon can then rotate the assembly to bring the rod in a position relative to the patient substantially identical to that in which it was before he passed the rod from the first to the second position. By rotation of the rod, it is thus possible to subject the appropriate rotation to the cage for its final positioning between the two vertebrae. Thanks to the system according to the invention, thus obtaining a very easy insertion of the cage between the two vertebrae and in particular a high accuracy in the amount of rotation that must be subjected to the cage. Once the cage is positioned, the surgeon unscrews the rod completely until it comes out of the cage.

Il est à noter, en outre, que suivant l'invention, si l'on souhaite par la suite retirer cette cage pour en mettre une nouvelle ou pour tout simplement l'enlever, le chirurgien n'a qu'à réintroduire la tige suivant l'axe sagittale par rapport au patient et tombe directement dans la bonne position, ce qui est particulièrement approprié. It should be noted, moreover, that according to the invention, if it is subsequently desired to remove this cage to put a new one or simply to remove it, the surgeon only has to reintroduce the next stem the sagittal axis with respect to the patient and falls directly into the right position, which is particularly appropriate.

De préférence, la cage est réalisée en PEEK. Cependant, d'autres matériaux, notamment métalliques ou céramiques bio compatibles usuels pour les cages intersomatiques peuvent être utilisés. Preferably, the cage is made of PEEK. However, other materials, especially metallic or organic ceramics compatible conventional for interbody cages can be used.

De préférence, la rotule est en titane. Il est à noter que la rotule, bien qu'un élément important de l'invention, n'est pas strictement nécessaire à l'obtention de l'effet de l'invention et, en particulier, on pourrait envisager un autre mode de réalisation dans lequel les trous 9 et 10 seraient taraudés pour obtenir la même fonction. Cependant, d'une part, la rotule a l'avantage d'assurer un bon guidage de la tige vers les trous borgnes 9 et 10 et, d'autre part, elle a aussi pour effet de donner à la cage une plus grande résistance aux contraintes verticales, ce qui permet d'éviter que celle-ci ne se fracture de manière intempestive. 12 Preferably, the ball is made of titanium. It should be noted that the patella, although an important element of the invention, is not strictly necessary to obtain the effect of the invention and, in particular, another embodiment could be envisaged. wherein the holes 9 and 10 would be tapped to achieve the same function. However, on the one hand, the ball has the advantage of ensuring good guidance of the rod towards the blind holes 9 and 10 and, on the other hand, it also has the effect of giving the cage greater strength vertical stresses, which prevents it from being broken inadvertently. 12
