Title
(EN) IMPLANTABLE DEVICE FOR THE FUSION OF TWO ADJACENT VERTEBRAE
(FR) DISPOSITIF IMPLANTABLE POUR LA FUSION DE DEUX VERTEBRES ADJACENTES
Abstract
(EN)
The invention relates to an implantable device for the fusion of two overlying and underlying vertebrae, comprising an intervertebral wedge (10) having a front part (20), a rear part (30), first and second lateral parts (40, 50) and a retaining means (60) arranged in relation to the front part (20) so as to block the migration of the front part (20) towards the spinal canal. The front part (20) comprises an upper supporting area (23) on the lamina of the overlying vertebra and a lower supporting area (26) on the lamina of the underlying vertebra (120), separated by a minimum distance in order to maintain an intervertebral gap. Advantageously, the rear part (30) comprises an upper supporting area (33) arranged beneath the upper supporting area (23) of the front part (20), and said device comprises first and second ligaments which are arranged particularly so as to bear against the first and second lateral parts.
(FR)
La présente invention concerne un dispositif implantable pour la fusion de deux vertèbres sus et sous-jacentes comprenant une cale intervertébrale (10) comprenant une partie antérieure (20), une partie postérieure (30), des première et seconde parties latérales (40, 50) et un moyen de retenu (60) agencé par rapport à la partie antérieure (20) en sorte de bloquer la migration de la partie antérieure (20) vers le canal rachidien. La partie antérieure (20) comprend une zone supérieure d'appui (23) sur la lame de la vertèbre sus- jacente et une zone inférieure d'appui (26) sur la lame de la vertèbre sous- jacente (120) distantes d'une distance minimum pour le maintien d'un écart intervertébral. Avantageusement, la partie postérieure (30) comprend une zone supérieure d'appui (33) disposée sous la zone supérieure d'appui (23) de la partie antérieure (20), et ledit dispositif comprend des premier et second ligaments agencés notamment pour venir en appui contre les première et seconde parties latérales.
