Abstract

The implant is in the form of a crescent (6,7) fitting the flat form of vertebral body. It has a crenellated surface (4) on its lower face and upper space, and having a central cavity to receive the transplant. There are fine rods (5) on the lower face for stiffening of the transplant and its frame.

Description

CAGE DE STABILISATION INTER CORPOREALE CAGE STABILIZATION INTER corporeal
La présente invention concerne un implant intersomatique creux destiné à restaurer un espace anatomique normal entre deux corps vertébraux, ouvrant les trous de conjugaisons et décomprimant les racines nerveuses. The present invention relates to a hollow intersomatic implant designed to restore a normal anatomic space between two vertebral bodies, opening conjugations holes and decompressing the nerve roots.

Par son effet distractant, la présente invention participe à la réduction des spondylolisthésis dégénératifs. By his distractant effect, the present invention helps reduce degenerative spondylolisthesis.

Sa forme géométrique elliptique en croissant-s'adaptant à la courbe anatomique du corps vertébral, offre une surface de contact optimisée avec les plateaux, et de ce fait, une stabilisation et une prise de greffe privilégiées. Its elliptical geometric crescent shape-adapting to the anatomical curve of the vertebral body, provides an optimized contact surface with the plates, and thereby stabilization and decision Preferred graft.

On connaît bien ce type de matériel suivant d'autres procédés, en forme de parallépipède rectangle ( US4 834.757), cylindre ( WO 89/12431, W091/06261, US 4.501.269) ovoïde (WO94/17759) ou sphérique (US 4.936.848 ). Are well known such material by other processes in the form of parallelepiped rectangle (US4 834 757), cylinder (WO 89/12431, W091 / 06261, US 4,501,269) ovoid (WO94 / 17759) or spherical (US 4936 .848).

Ces dispositifs restituent un espace intersomatique anatomique, mais ne présentent pas une surface greffante et une stabilisation inter-corporéale suffisantes. These devices restore an anatomical interbody space, but do not exhibit greffante surface and sufficient inter-corporeal stabilization. Par ailleurs, leur implantation reste, pour la plupart, exclusivement postérieure. Furthermore, their presence remains, for the most part only later.

En dernier lieu, plusieurs cas de mobilisation de l'implant ont été rapportés à distance et dans des conditions variables d'implantation. Finally, several cases of mobilization of the implant were reported in remote and implantation variable conditions.

La présente invention a pour objet de palier ces inconvénients et propose un implant à structure rigide en forme de croissant elliptique muni d'un logement permettant la mise en place de la greffe. The present invention relates to a bearing of these disadvantages and provides a rigid structure shaped implant elliptical crescent provided with a housing for the establishment of the graft. Les deux surfaces en contact avec les corps vertébraux adjacents sont ouvertes afin de permettre la fusion osseuse. The two surfaces in contact with the adjacent vertebral bodies are open to allow bone fusion. La part représentée par la structure de l'implant est considérablement réduite au regard de la surface de contact. The part represented by the structure of the implant is substantially reduced in relation to the contact surface. La qualité et la répartition du pontage osseux s'en trouvent améliorés. The quality and distribution of bone bridging are improved.

La présente invention est munie d'un taraudage à chaque extrémité permettant le positionnement d'un préhenseur-introducteur adapté aux voies chirurgicales antérieure et postérieure. The present invention is provided with an internal thread at each end allowing the positioning of a gripper-introducer adapted to the anterior and posterior surgical passages.

Les bords de l'implant en contact avec les corps vertébraux présentent une surface en contre -dépouille perpendiculaires à l'axe de la pièce lui assurant une stabilisation primaire satisfaisante. The edges of the implant in contact with the vertebral bodies have a surface against -dépouille perpendicular to the axis of the part giving it a satisfactory primary stabilization.

La forme caractéristique de l'implant limite la possibilité de mobilisation in-situ et notablement, de migration postérieure dans la période qui suit l'implantation. The characteristic shape of the implant limits the possibility of mobilization in situ and remarkably, posterior migration in the period following implantation.

La surface inférieure de l'implant présente un procédé d'usinage assurant la préhension et la stabilisation des greffons. The lower surface of the implant has a machining process ensuring grip and the stabilization of grafts.

Un impacteur de forme géométrique égale à la lumiére intérieure de l'implant permet le remplissage et le tassement des greffons dans la structure. An impactor geometric shape equal to the inner lumen of the implant allows the filling and compaction of the grafts in the structure.

Les surfaces de contact sont paralléles ou angulées à effet lordosant selon le site d'implantation, l'anatomie du rachis et l'indication opératoire. The contact surfaces are parallel or angled to lordosing effect as the site of implantation, the anatomy of the spine and the surgical indication.

- La figure 1 représentée en coupe montre les 2 surfaces de contact parallèles (1). - Figure 1 shown in cross section shows the two parallel contact surfaces (1).

A chaque extrémité est réalisé un taraudage ( 3 ) pour le vissage du préhenseur-impacteur. At each end there is formed a thread (3) for screwing the grapple impactor.

- La figure 2 montre,en coupe longitudinale, l'angle des surfaces de contact. - Figure 2 shows, in longitudinal section, the angle of contact surfaces. On voit les contre-dépouilles ( 4 ) permettant la stabilisation primaire de l'implant. Seen against the undercuts (4) for primary stabilization of the implant. Le logement ( 8 ) permet la mise en place des greffons. The housing (8) allows the implementation of the grafts.

- La figure 3 montre la cage de face antérieure avec le taraudage pour la mise en place intersomatique. - Figure 3 shows the front cage with the internal thread for the establishment interbody.

- La figure 4 montre la cage de face postérieure avec le meme taraudage. - Figure 4 shows the cage rear face with the same thread.

- La figure 5 montre la cage vue de dessus. - Figure 5 shows the cage viewed from above. Le rayon ( 7 ) congrue avec la courbe extérieure d'un corps vertébral. The radius (7) congruent with the outer curve of a vertebral body. La courbe ( 6 ) suit ce profil. Curve (6) follows the profile. La face inférieure ( 2 ) est munie de barettes ( 5 ) permettant de maintenir les greffons en place dans l'implant. The lower face (2) is provided with barrettes (5) for holding the graft in place in the implant.
