Abstract:
Vertebral fixator forming a discal prosthesis having substantially the height of an intervertebral disk to be replaced comprising at least one essentially rigid first element (10) intended to be fixed to the articular face of one (V1) of two adjacent vertebrae, and at least one essentially rigid second element (11) fixed to the articular face of the other vertebrae (V2), the said essentially rigid first and second elements (10, 11) being connected by at least one intermediate element (20) having articular mobility, the said essentially first and second elements and the said intermediate element being shaped dimensionally for introduction into the intervertebral space via a posterior or lateral surgical route, the said essentially rigid first and second elements having fixation members (30) capable, once the fixator has been arranged in the intervertebral space, of protruding from the two rigid elements (10, 11) essentially at right angles to their surfaces in contact with the corresponding surface of the vertebral body, in order to penetrate the vertebral body.
