Spinal osteosynthesis device and the straightening device of the connectors with respect to the axial screw poly

摘要

The osteosynthesis assembly, comprising pedicular anchoring screws (4) and linking rods, has L-shaped connectors between the rods and screws. Each connector comprises a body (5) with an oval hole (6) for the linking rod, a threaded hole (7) for a locking screw, and a branch with a second threaded hole (9) for fastening it to the spherical head of the anchoring screw by means of a threaded plug (12). The plug has an inner cylindrical or conical tip (15) that fits into the head of the anchoring screw, and an outer threaded surface to engage with the connector.
