摘要：
The present invention relates to an intervertebral disc prosthesis and insertion instrumentation, the prosthesis comprising at least first and second osseous anchoring means, the first osseous anchoring means disposed proximal to the periphery of the plate on which it is situated and the second osseous anchoring means being offset along the antero-posterior axis, the second osseous anchoring means comprising a basal portion and a sharp-edged portion of width narrower than the basal portion. The instrumentation comprises a rod fitted with at least two feet forming a clip and sliding in a tube, sliding the rod in the tube, in the direction of the manipulation end, causing closing of the clip by contact between the exterior of the feet and a truncated portion of the tube and sliding the rod in the tube, in the direction of the prehension end, causing opening of the clip by contact between an axis and the interior of the feet of the rod.
