Title (EN) THREADED FUSION CAGE ANCHORING DEVICE AND METHOD
(FR) PROCEDE ET DISPOSITIF D'ANCRAGE D'UNE CAGE DE FUSION FILETEE
Abstract:
(EN) This invention is an anchoring device and method for stabilizing adjacent vertebral joints. The anchoring device (12) includes an anchoring plate (26) adapted to be secured to at least one vertebral disc having a central portion (32), extended end portions (34), and at least one lateral extension (60). The central portion includes an anchoring nut (28) for fastening the anchoring plate to a vertebral implant (24), and the end portions include anchoring screws (30) for fastening the anchoring plate to the vertebral disc. The vertebral implant is preferably a threaded fusion cage (24), wherein the anchoring nut is rotatable fixed to both the anchoring plate and the threaded fusion cage. The anchoring device preferably includes the central portion, and each extended end portion having at least one locking tab (48, 52) for rotatable locking the anchoring nut and anchoring screws. Additionally, the central portion includes a plurality of a projecting detent (42) along an outer periphery which mate with corresponding slots (44) on the threaded fusion cage.
(FR) L'invention porte sur un dispositif d'ancrage et sur un procédé de stabilisation d'articulations vertébrales adjacentes. Le dispositif d'ancrage (12) comprend une plaque d'ancrage (26) conçue pour être fixée à au moins un disque intervertébral comportant une partie centrale (32), des parties terminales étendues (34) et au moins une extension latérale (60). La partie centrale comprend un écrou d'ancrage (28) permettant de fixer la plaque d'ancrage à un implant vertébral (24), et les parties terminales comportent des vis d'ancrage (30) permettant de fixer la plaque d'ancrage au disque intervertébral. L'implant vertébral est de préférence une cage de fusion filetée, l'écrou d'ancrage pouvant tourner tout en étant fixé à la fois à la plaque d'ancrage et à la cage de fusion filetée. Le dispositif d'ancrage comprend de préférence la partie centrale, et chaque partie terminale étendue étant pourvue d'au moins une patte de verrouillage (48, 52) qui bloque par rotation l'écrou et les vis d'ancrage. La partie centrale comprend, de plus, sur sa périphérie externe, une pluralité d'ergots d'encliquetage saillants (42) qui s'adaptent dans les fentes correspondantes (44) de la cage de fusion filetée.
