CA 2436902

The invention concerns an intervertebral stabilising device, designed to link two neighbouring vertebrae (2, 2'), characterised in that it comprises an upper stop element (26), integral with the upper vertebra (2) and a lower stop element (34) integral with the lower vertebra (2') said extra-disc stop elements (26, 34) having mutual support surfaces (26', 38) adapted to allow a mutual rotation of said upper (2) and lower (2') vertebrae about the patient's transverse and sagittal axes, and to prevent a mutual rotation of said two vertebrae about a vertical axis, said support surfaces being further adapted to allow mutual translation of said vertebrae in a single direction along the sagittal axis, to allow translation between said two vertebrae in both directions along the vertical axis, and to prevent translation between said two vertebrae in both directions along the transverse axis.

Dispositif de stabilisation intervertébral, destiné à relier deux vertèbres voisines (2, 2'), caractérisé en ce qu'il comprend un élément de butée supérieur (26), solidaire d'une vertèbre supérieur (2), ainsi qu'un élément de butée inférieur (34), solidaire d'une vertèbre inférieure (2'), ces éléments de butée extra-discaux (26, 34) possédant des surfaces d'appui mutuelles (26', 38) aptes à autoriser une rotation mutuelle desdites vertèbres supérieure (12) et inférieure (2') autour d'axes transversal et sagittal du patient, ainsi qu'à empêcher une rotation mutuelle de ces deux vertèbres autour d'un axe vertical, ces surfaces d'appui étant en outre aptes à autoriser une translation mutuelle de ces vertèbres dans un unique sens selon l'axe sagittal, à autoriser une translation entre ces deux vertèbres dans les deux sens selon l'axe vertical, et à interdire une translation entre ces deux vertèbres dans les deux sens selon l'axe transversal.
