Title
(EN) HINGE-LINK SPINAL CORRECTION DEVICE AND METHOD
(FR) DISPOSITIF ET PROCÉDÉ DE CORRECTION SPINALE DE TYPE CHARNIÈRE
Abstract
(EN)
A device for spinal correction includes a stabilizer assembly including a hinge including a first rod-bearing leaf; a second rod-bearing leaf rotatably coupled to the first rod-bearing leaf to provide coronal or sagittal freedom of movement, or both, of the stabilizer assembly; a locking mechanism to lock the first and second rod-bearing leaves at a desired angle; a first stabilizing rod coupled to the first rod-bearing leaf; a second stabilizing rod coupled to the second rod-bearing leaf; and a plurality of monoaxial or polyaxial links, wherein each monoaxial or polyaxial link is movably coupled to the first or second stabilizing rod and is movably couplable to a first spinal rod or a second spinal rod fixed to the spine; wherein the stabilizer assembly is couplable to the first or second spinal rod to stabilize the spine to prevent compression, distraction, or translation of the spinal cord during a spinal correction.
(FR)
Selon la présente invention, un dispositif de correction spinale comprend un ensemble stabilisateur comprenant une charnière comprenant une première lame porte-tige ; une seconde lame porte-tige accouplée rotative à la première lame porte-tige afin de fournir une liberté coronale ou sagittale de mouvement, ou les deux, de l'ensemble stabilisateur ; un mécanisme de verrouillage permettant de verrouiller les première et seconde lames porte-tiges à un angle souhaité ; une première tige de stabilisation accouplée à la première lame porte-tige ; une seconde tige de stabilisation accouplée à la seconde lame porte-tige ; et une pluralité de liaisons monoaxiales ou polyaxiales, chaque liaison monoaxiale ou polyaxiale étant accouplée mobile à la première ou à la seconde tige de stabilisation et étant accouplée mobile à une première tige spinale ou à une seconde tige spinale fixée à la colonne vertébrale ; l'ensemble stabilisateur pouvant être accouplé à la première ou à la seconde tige spinale afin de stabiliser la colonne vertébrale afin d'empêcher la compression, la distraction ou la translation de la moelle épinière pendant une correction spinale.
