This invention is a spinal fixation device (12, 14, 26) for stabilizing vertebrae. A hollow screw (14) is inserted into a hole saw recess (50) in each adjoining vertebrae. A channel is cut into the vertebrae into which a joining rod (12) is inserted such that no part of the device protrudes above the bone. A locking cap (26) is used to secure the rod (12) to the screws (14).

L'invention traite d'un dispositif de contention vertébrale (12)(14)(26) pour stabiliser les vertèbres. Une vis creuse (14) est insérée dans un évidement (50) ménagé pour former un trou dans chaque vertèbre contigüe. Un canal est formé dans les vertèbres dans lequel on insère une tige d'assemblage (12) de telle sorte qu'aucune partie du dispositif ne dépasse au-dessus de l'os. Un bouchon de blocage (26) permet de fixer la tige (12) aux vis (14).
