摘要
目的 探讨基于影像学方法评估特发性脊柱侧弯(IS)内固定矫正手术的疗效.方法 回顾性分析经内固定手术治疗的 IS患者 46 例,手术前后均行脊柱全长正侧位数字摄影(DR)检查、CT平扫并进行CT后处理重建.分别测量术前、术后DR和CT主弯Cobb角、胸椎后凸角、冠状面平衡和矢状面平衡值;术后CT多平面重建(MPR)评估螺钉置入情况.结果 本组患者术前、术后DR和CT主弯 Cobb角、胸椎后凸角、冠状面平衡均有显著统计学差异(P<0.001);矢状面平衡均有统计学差异(P<0.05).本组共植入螺钉数量 854枚,其中 775枚螺钉完全在椎弓根内,总体置放准确率为 90.75%.结论 特发性脊柱侧弯内固定矫正手术疗效明确,DR和 CT均可提供评估疗效的客观指标,CT-MPR还可精准评估螺钉不良置入.
Abstract
Objective To explore the efficacy evaluation of corrective surgery for idiopathic scoliosis(IS)based on radiological methods.Methods A retrospective analysis was conducted on 46 patients with IS who underwent internal fixation surgery.Preoperative and postoperative e-valuations included full-length anteroposterior digital radiography(DR),CT scans,and post-processing reconstructions.Preoperative and postoperative DR and CT main curve Cobb angles,thoracic kyphosis angles,coronal balance,and sagittal balance values were taken as measurements.Postoperative CT multi-planar reconstructions(MPR)were used to assess screw placement.Results There were significant differences in Cobb Angle,thoracic kyphosis Angle and coronal balance of DR And CT before and after surgery(P<0.001).There were statistical differences in sagittal plane balance(P<0.05).A total of 854 screws were implanted in this study,775 of which were completely within the pedicle,and the overall placement accuracy was 90.75%.Conclusion The efficacy of corrective surgery for idiopathic scoliosis with internal fixation is clear,and DR and CT can provide objective indicators.CT-MPR images can also provide precise evaluation of bad screw placement.
