Title
(EN) FACET JOINT STABILIZATION
(FR) STABILISATION DE FACETTES ARTICULAIRES
Abstract
(EN)
Various implementations for therapy to facet joints connecting vertebrae are disclosed including: A) Facet joint stabilization that may be implemented using stabilization band that maintains tension between two anchors. The stabilization band may be retained in any one of a number of ways including the use of an anti-slip device such as a mechanically deformed crimp that abuts one of the anchors. B) Facet joint augmentation may be implemented by dilating the facet joint and inserting a facet joint spacer before adding a facet joint stabilization assembly. The facet joint augmentation may include connecting a tail section of the facet joint spacer to the first anchor used in the facet joint stabilization assembly. C) Facet joint immobilization may be implemented by inserting a fastener across the facet joint and into the vertebra so that the assembled fastener expands inside the vertebra.

L'invention concerne divers modes de réalisation permettant de traiter des facettes articulaires reliant des vertèbres et qui comprennent: A) un dispositif de stabilisation de facettes articulaires utilisant une bande de stabilisation qui maintient une tension entre deux ancres. La bande de stabilisation peut être retenue de diverses manières, y compris au moyen d'un dispositif antiglissement tel qu'un élément de serrage mécaniquement déformé aboutant l'une des ancres. B) L'augmentation d'une facette articulaire, obtenue par l'expansion de celle-ci et l'insertion d'un espaceur de facette articulaire avant l'ajout d'un ensemble stabilisation de facette articulaire. L'augmentation d'une facette articulaire comprend l'étape consistant à relier une partie queue de l'espaceur de facette articulaire à la première ancre utilisée dans l'ensemble stabilisation de facette articulaire. C) L'immobilisation d'une facette articulaire, mise en oeuvre par l'insertion d'un élément de fixation traversant la facette articulaire et pénétrant la vertèbre, de sorte l'élément de fixation assemblé se déploie à l'intérieur de la vertèbre.
