术中锥束CT辅助下脊柱侧凸畸形椎弓根螺钉置入的精确性及安全性
Accuracy and safety of pedicle screw placement for spinal deformity under intraoperative CT-assisted
摘要
Abstract
Objective To evaluate the accuracy and safety of pedicle screw placement for spinal deformity under intraoperative CT-as-sisted.Methods The clinical data of 28 patients with spinal deformity,who underwent intraoperative CT-assisted placement of pedicle screws in our hospital from March 2014 to March 2017,were analyzed retrospectively.Intraoperative CT-assisted placement of pedicle screws was to observe the position of pedicle screws and adjust the screw position.The safety of pedicle screw fixation was assessed by the postoperative complications.Results All 28 patients of scoliosis were successfully performed surgery.A total of 402 pedicle screws were placed in the spines and the placements of 64 screws of them were adjusted according to intraoperative CT findings.Of 402 screws,377 were placed in the pedicles,13 by grade 1 pedicle breach,8 by grade 2 pedicle breach and 4 by grade 3 pedicle breach according to Gertzbein-Robbins classifi-cation of pedicle screw placement accuracy.No complication was directly related to the screws placement.No patient required reoperation due to the misplacement of the pedicle screws.Conclusion Intraoperative cone-beam CT scan can help the surgeon improve the accuracy and safety of pedicle screw placement for spinal deformity with less complication.关键词
