[The prevention and treatment of complications with pedicle screws].

Pedicle screws are more commonly used by spinal surgeons recently. Although Roy-Camile, Dick, Steffee, R-F etc., are all different surgical procedures, all need pedicle screw techniques. Up to March 1991, 61 cases with 334 screws inserted by Steffee and Dick operations had been performed in our hospital. Neurological symptoms, among all complications, are the most serious problems associated with these procedures. By analyzing the insertion point, transverse screw angle, sagittal angle and other causes of complications of pedicle screws, we present here our experiences for prevention and treatment of these complications.
