ABSTRACT:
A pedicle screw with a closure device including a seat element and a closure cap for quick closure of the seat element of the pedicle screw. An elastic rod element inserted therein in the seat recess, which element serves to stabilize a vertebral column, is held in a form-locking way. The closure cap of the closure device has the function of a cross-brace, and can transfer the forces absorbed by it from the rod element to the pedicle screw. Disposed on the closure cap with a holding recess are engagement elements which, during insertion of the closure cap, automatically lock in place in a stable position in the seat element provided with a U-shaped seat recess. The seat recess and the holding recess preferably have a ridged or grooved structure corresponding to the rod element used.
