ABSTRACT
Objective To compare the effect of pedicles screw fixation through entry point of the “人" shape crest and traditional entry point (Weinstein method). Methods Ninety-two patients of lumbar spine disorders were treated by pedicles screw fixation combined with bone grafting through posterior approach. The screws were placed through the traditional entry point among 45 patients (group A, transverse process method, 186 screws), the others were through entry point of the “人" shape crest (group B, “人" shape crest method, 196 screws). The condition of accuracy of screw placement, operation time, bleeding amount and injury were compared. Results All patients accepted the examination of X-ray and CT scan after operation. The rate of screw bad placement was 6.5% in group A and 2.0% in group B, the incidence of injury of nerve and blood vessel was 8.9% in group A and 2.1% in group B. The accuracy of screw placement, operational time and bleeding amount in group B were significantly better than those in group A (P
