Abstract

Ce dispositif de stabilisation (150), destiné à relier deux vertèbres, comprend au moins deux chambres (156, 158, 186, 188) placées au voisinage desdites vertèbres, lesdites chambres renfermant un fluide d'amortissement. Il est prévu des moyens (192, 194) de mise en communication fluidique à débit contrôlé de ces chambres, ce qui permet d'amortir de façon satisfaisante les mouvements du patient.This stabilization device (150), intended to connect two vertebrae, comprises at least two chambers (156, 158, 186, 188) placed in the vicinity of said vertebrae, said chambers containing a damping fluid. Means (192, 194) are provided for placing fluid communication at a controlled rate in these chambers, which makes it possible to satisfactorily dampen the movements of the patient.
