[Analysis of 112 cases of pedicular screw placement].
This article presented 464 pedicular screw placement in 112 patients who were treated with a method of internal spinal fixation system. Radiographic films or CT scans were used to assess the accuracy of the screw insertion into the vertebral body through pedicle and the angle of inserted screw to the end plate of the vertebral body. Results revealed that 88.7% of screw placement were considered excellent and good, 11.3% were acceptable and poor. There was no neurological complication at all. It is concluded that preoperative radiographic films in prone position to determine the point of entry and accurate marking of the pedicle were required for pedicular screw placement even without roentgenoscopic monitoring during operation. The indications and techniques were discussed.
