A system for setting cervical vertebrae from behind.

摘要

Hooks (10) and plates (12) are used together with a number of jointed segments or cylinders (1) crossed longitudinally and vertically by a web (4) housing a connecting wire (8) that can be tightened with tightening means and locked by a screw (7) lying crosswise to each segment (1). The system can be used to join all the required levels; neither the point of insertion of the screws nor the position of the hooks are predetermined; and it can be used after laminectomy. <IMAGE> <IMAGE>
