Title
(EN) BONE PLATE SYSTEM AND METHODS
(FR) SYSTEME DE PLAQUES OSSEUSES ET METHODES ASSOCIEES
Abstract
(EN) Bone plate systems and retainers are provided for surgical implants and bone repair. The bone plate is multi-tiered for receiving bone anchors or screws for securing multiple bones or bone fragments in a desired relationship. The plate includes bores for receiving the screws, and the bores may permit and define a translation path for the screws relative to the plate. The retainers are held in a recess in the bores to prevent screw back-out. Once the screw is seated with the plate, the retainer rests over a top surface of the screw to impede screw back-out from the plate. The retainer may expand to permit driving a screw therethrough and may contract once the screw is seated within the plate so the retainer is in a configuration for preventing back-out. Tools and methods are also provided for implantation and removal of the plates and the screws.
(FR) L'invention concerne des systèmes de plaques osseuses et des éléments de fixation facilitant les implants chirurgicaux et la réparation osseuse. La plaque osseuse est étagée pour recevoir des dispositifs d'ancrage osseux ou des vis permettant de fixer des os ou des fragments osseux multiples de manière désirée. La plaque comprend des orifices destinés à recevoir les vis, et les orifices permettent et définissent une trajectoire de translation pour les vis par rapport à la plaque. Les éléments de fixation sont maintenus dans la cavité des orifices afin d'éviter le retrait des vis. Lorsque la vis est positionnée dans la plaque, l'élément de fixation repose sur une surface supérieure de la vis afin d'empêcher le retrait de la vis de la plaque. L'élément de fixation peut s'étendre afin de permettre l'entraînement de la vis, et peut se contracter lorsque la vis est positionnée dans la plaque de façon à se trouver dans une configuration empêchant tout retrait. L'invention concerne également des outils et des méthodes d'implantation et de retrait des plaques et des vis.
