Abrégé
(EN)
Fixing device for fixing two vertebra parts with respect too one another, and the method for fixing two vertebra parts. The fixing device comprises fixing plates which have to be secured to the relevant vertebra parts. The fixing plates are provided with countersunk openings for receiving the heads of fixing screws. Sleeves which project out of the fixing plates and are to be held in the vertebra adjoin these fixing openings. The fixing plates are fixed with respect to one another with the aid of a connecting system comprising two lips, which lie at a distance from one another, in one fixing plate and a tongue, which can be placed between the said lips, belonging to the other fixing plate. A clamping action of the tongue between the lips can be brought about by a spreading action.
(FR)
L'invention concerne un dispositif de fixation de deux parties de vertèbres l'une par rapport à l'autre, et son procédé de fixation. Ce dispositif de fixation comprend des plaques de fixation à fixer sur des parties de vertèbres appropriées. Les plaques de fixation sont pourvues d'ouvertures fraisées permettant de loger des têtes de vis de fixation. Des manchons se projetant hors des plaques de fixation et maintenus dans la vertèbre se rattachent à ces ouvertures de fixation. Lesdites plaques de fixation sont montées les unes par rapport aux autres, au moyen d'un système de couplage pourvu de deux lèvres séparées l'une de l'autre, sous forme d'une plaque de fixation et d'une languette, qui peut être placée entre lesdites lèvres et qui fait partie de l'autre plaque de fixation. On peut serrer la languette entre les lèvres en l'écartant.
