<p>A pedicle screw (3) fastener (1) with a take-up element (4) and a U-shaped device between which a closure cap (5) is inserted for rapid locking of element (4) also has an element (14) stabilizing the vertebral column. A pedicle screw (3) fastener (1) with a take-up element (4) and a U-shaped device between which a closure cap (5) is inserted for rapid locking of element (4) also has an element (14) stabilizing the vertebral column, this element (14) having a ribbed and grooved surface allowing gripping at the contact position such that the closure cap (5) functions as a crossbeam and transmits the forces in the longitudinal direction of the stabilizer element (14) to the screw (3).</p> |
