Title
(EN) BONE PLATE SYSTEM
(FR) SYSTÈME DE PLAQUE VISSÉE
Abstract
(EN)
Bone plate systems are provided for surgical implants and bone repair. The bone plate is multi-tiered for receiving bone anchors screws for securing a plurality of bones or bone fragments in a desired relationship. The plate members include throughbores for receiving a pivot base therein, with head ends of the bone anchors being secured in the pivot bases. The throughbores may permit and define a translation path for the pivot base and the bone anchor secured therein relative to the plate. Pivot members extending between the pivot base and the plate member facilitate pivoting and optional translation of the pivot base relative to the plate. With the bone anchor seated within the pivot base, an apparatus for inhibiting screw back out is employed.

La présente invention concerne des systèmes de plaque vissée destinés à des implants chirurgicaux et la réparation osseuse. La plaque vissée comporte différents niveaux pour recevoir les vis d'ancrages osseux et fixer une pluralité d'os ou de fragments osseux selon une relation souhaitée. La plaque comprend des trous traversants pour recevoir une base de pivot, les extrémités des têtes des ancrages osseux étant fixées dans les bases de pivot. Les trous traversants peuvent permettre et définir une trajectoire de translation par rapport à la plaque pour la base de pivot et l'ancrage osseux fixé dans celle-ci. Les éléments pivot s'étendant entre la base de pivot et l'élément plaque facilitent la rotation et éventuellement la translation de la base de pivot par rapport à la plaque. L'ancrage osseux installé dans la base de pivot permet d'utiliser un appareil qui empêche le retrait de la vis de la plaque.
