Abstract

The system consists of a transverse bar (1) for each vertebra, having its ends fixed to pediculo-vertebral screws (B) with specially-shaped heads (5,6). Each bar varies in length according to the inter-pedicule distance of each type of vertebra, and it has a ring (2) on each end inclined in relation to its lengthwise axis and having a hexagonal inner surface (3) shaped to engage with one portion (5) of the screw head. The screws have central channels (4) which allow them to be fitted over guide pins, and their heads have upper threaded sections (6) to receive locking nuts (7) with central threaded apertures (8) and holes (9) for a screw driver.

Le dispositif est une variante des matériels utilisés pour l'ostéosnthése rachidienne appuyé sur des vis l:édiculovertébraIes Introduites par vole postérieure (fig 1).  The device is a variant of the equipment used for spinal osteosthesis supported on screws (1) which are introduced posteriorly (FIG. 1).

Le dispositif de base est composé de 3pièces séparées (fig 2): - la pièce (A) comporte une barre (1) dont la longueur varie avec l'écart interpédiculaire. Elle dispose à sets deux extrémités d'un anneau (2) incliné selon l'orientation donnée aux vis. Ces deux anneaux disposent en leur centre d'un logement vertical (3) ouvert sur ses deux faces, visant à recevoir la partie (5) de la vis (B). La surface interne de ces logements est taillée selon le mode hexagonal ou selon toute autre forme capable de bloquer les contraintes en torsion exercées sur les deux vis lorsqu'elles sont en place. The basic device is composed of 3 separate pieces (FIG. 2): the workpiece (A) comprises a bar (1) whose length varies with the interpedicular distance. It has sets two ends of a ring (2) inclined according to the orientation given to the screws. These two rings have in their center a vertical housing (3) open on both sides, to receive the portion (5) of the screw (B). The inner surface of these housings is cut in the hexagonal mode or in any other form capable of blocking the torsional stresses exerted on the two screws when they are in place.

- la vis (B) est canulée en son centre (4) afin de recevoir une broche qui précède leur introduction en bonne place. La vis (B) dispose sur son extrémité proximale de deux parties (fig 3): une partie intermédiaire (5) qui vient se caler dans le logement (3) de la partie (2) de la pièce (A) et une partie terminale (6) qui, lorsque la vis (B) est en place, dépasse la face supérieure de l'extrémité (2) de la pièce (A). Cette partie est munie d'un pas de vis visant à recevoir l'écrou de blocage (7).- The screw (B) is cannulated at its center (4) to receive a pin which precedes their introduction in a good place. The screw (B) has on its proximal end two parts (FIG. 3): an intermediate part (5) which is wedged in the housing (3) of the part (2) of the part (A) and a terminal part (6) which, when the screw (B) is in place, exceeds the upper face of the end (2) of the piece (A). This part is provided with a screw thread for receiving the locking nut (7).

- l'écrou de blocage (7 > verrouille chacune des 2 vis (B) emboîtées dans les deux extrémités (2) de la pièce (A). Cet écrou visse sa partie (8) sur la partie (6) de la vis (B) au moyen d'un tournevis qui s'emboite dans les deux orifices (9) situés à sa face supérieure. - the locking nut (7> locks each of the two screws (B) fitted in the two ends (2) of the part (A) .This nut screws its part (8) on the part (6) of the screw ( B) by means of a screwdriver which fits into the two orifices (9) situated at its upper face.

- chaque dispositif de base comporte donc une barre (A) et deux vis (B) verrouillées chacune par un écrou (7). Les dispositifs de base placés dans chaque vertèbre sont solidarisés les uns aux autres par deux barres verccales (C) placées de part et d'autre des apophyses épineuses. Elles sont fixées à leur oectrémité sur la barre (A) par des crochets (D) (fig 4). Les crochets (D) possèdent un corps creux glissé sur la barre (C). Ils possèdent sur l'une de leur face un crochet que l'on agrippe sur la barre (A). Le corps de la pièce (C) est biloqué sur la barrie (C) par un écrou (11). La longueur de la pièce (A) et l'orientation des vis (B) sont données par le viseur (E) (fig 5). Le viseur (E) est une pièce transversale manipulée par une pièce à main, que l'opérateur place transversalement conte les lames vertébrales et entre les apophyses épineuses.- Each basic device therefore comprises a bar (A) and two screws (B) each locked by a nut (7). The basic devices placed in each vertebra are secured to each other by two vibratory bars (C) placed on either side of the spinous processes. They are attached to their electromagnet on the bar (A) by hooks (D) (fig 4). The hooks (D) have a hollow body slid on the bar (C). They have on one of their face a hook that is gripped on the bar (A). The body of the piece (C) is bilocated on the barrie (C) by a nut (11). The length of the workpiece (A) and the orientation of the screws (B) are given by the viewfinder (E) (fig 5). The viewfinder (E) is a transverse piece manipulated by a handpiece, which the operator places transversely to the vertebral blades and between the spinous processes.

La barre de visée (E) est munie de canaux (11) de part et d'autre de la pièce à main. Ils sont écartes les uns des autres de quelques mm. lls reçoivent les broches qui guident les vis (B) àleurs points d'errée apophysaires selon l'écart interpédiculaire propre à chaque type de vertèbre. The sighting bar (E) is provided with channels (11) on either side of the handpiece. They are separated from each other by a few mm. They receive the pins that guide the screws (B) to their apophyseal wander points according to the interpedicular gap specific to each type of vertebra.
