Abstract

Ce dispositif de stabilisation intervertébrale, destiné à relier deux vis pédiculaires s'étendant dans deux vertèbres adjacentes, comprend deux organes rigides (10, 20) destinés à être articulés par rapport aux deux vis pédiculaires, un élément amortissant (30) rapporté sur ces organes rigides, de façon à être solidaire de ces derniers à la fois en compression et en extension, ainsi qu'au moins une paroi (40) s'étendant axialement à partir d'un premier organe rigide (10), au voisinage de la périphérie de l'élément amortissant (30) et en direction de l'autre organe rigide (20), de manière à former à la fois une butée en compression ainsi que des moyens de centrage afin d'éviter le désaxement de ces deux organes rigides.
