Title (EN) SYSTEMS AND METHODS FOR POSTERIOR DYNAMIC STABILIZATION
(FR) SYSTÈMES ET PROCÉDÉS POUR UNE STABILISATION DYNAMIQUE POSTÉRIEURE
Abstract:
(EN) A system for providing dynamic stabilization and balance control at a vertebral motion segment has first and second bridge elements and at least one bias element. The bridge elements anchor to adjacent vertebrae with polyaxially adjustable anchoring members, and the bias elements attach to each bridge element to span between them. Each bias element has two fixation portions and a bias body extending between the fixation portions. Each bias element may comprise an elastically deformable material to provide dynamic stabilization with motion, or may comprise rigid material to provide rigid stabilization, and both bias element types may be included in one system. The bias elements are attachable to the bridge elements at discrete attachment locations, or at non-discrete attachment locations. Alternate embodiments may include three or more bridge elements on adjacent vertebrae, and multiple bias elements. A tensioning tool may provide adjustable tension to an elastically deformable bias element.
(FR) L'invention concerne un système permettant d'obtenir une stabilisation dynamique et une commande d'équilibre, au niveau d'un segment de déplacement vertébral. Ce système comprend un premier élément pont et un second élément pont et au moins un élément de contrainte. Les éléments ponts servent à ancrer les vertèbres adjacentes aux éléments d'ancrage polyaxialement réglables, et les éléments de contrainte servent à fixer chaque élément pont de sorte que ce dernier s'étende entre lesdits éléments de contrainte. Chaque élément de contrainte présente deux parties de fixation et un corps de contrainte s'étendant entre les parties de fixation. Chaque élément de contrainte peut comprendre un matériau élastiquement déformable pour obtenir une stabilisation dynamique lors d'un déplacement, ou peut comprendre un matériau rigide pour obtenir une stabilisation rigide, et les deux types d'éléments de contrainte peuvent être intégrés dans un même système. Les éléments de contrainte peuvent être fixés aux éléments ponts à des emplacements de fixation discrets ou à des emplacements de fixation non discrets. D'autres modes de réalisation de l'invention peuvent comprendre au moins trois éléments ponts sur les vertèbres adjacentes, et plusieurs éléments de contrainte. Un instrument de tensionnement peut permettre d'obtenir une tension réglable sur un élément de contrainte élastiquement déformable.
