EXTRA-DISCAL INTER-VERTEBRAL PROSTHESIS FOR CONTROLLING THE VARIATIONS OF THE INTER-VERTEBRAL DISTANCE BY MEANS OF A DOUBLE DAMPER

摘要

This invention relates to a prosthesis with double damper performing the function of intervertebral stabilizer, wherein it comprises at least two identical elements assembled together and comprising means for regulating the bending-stretching movement between two vertebrae so as to approach as closely as possible the physiological course of a discal movement.
