The bone screw (1), and especially a pedicle screw, has a screw shaft with a thread. An opening along the screw is for the insertion of a wire. The bone screw has at least one fastener to secure a stiffener inserted at least partially into the opening as a pin or rod and the like. The bone screws are inserted into the pedicles (3) flanking a vertebra (5).
