Abstract:

A vertebral support device () is disclosed, which in various embodiments comprises at least two osseous anchoring implants (), each designed to be anchored to a vertebra, and at least one linking element () fixed to the osseous anchoring implants () by fasteners () that maintain a fixed angle between the longitudinal axis (L) of the linking element () passing through rigid elements () of the linking element () and the insertion axis (DV) of the implants (). The linking element () includes at least one elastic dampening element () that that allows the implant-bearing vertebrae some freedom of movement. The dampening element () accommodates the stresses imposed on the linking element () during movement of the vertebrae and tends to return the support device () to its normal configuration.
