Vertebral osteosynthesis material, has connecting rods that are fixed to vertebra and include connection parts that are fixed to screw, where each part is immobilized on screw independent of locking rod in part

摘要

The material has connecting rods (2) that are linked to a pedicular screw (1). The connecting rods are fixed to the vertebra, and the connection parts (3) of the connecting rods are fixed the pedicular screw. Each connection part is conformed in such a way that the immobilization of the part on the screw is made independent of locking the connecting rod in the connection part.
