Accurate insertion of pedicle screws in scoliosis patients is a challenge for surgeons. Computer-assisted navigation techniques might help improve the accuracy of screw placement, thereby avoiding complications. Thus, the objective of this present work is to compare the accuracy and postoperative assessment of pedicle screw placement in scoliosis patients using a computer-assisted navigation technique and using a conventional free-hand method.
A search of the PubMed, Cochrane, and Web of Science databases was executed. In vivo comparative studies that assessed the accuracy and postoperative evaluation of pedicle screw placement in scoliosis patients with or without navigation techniques were chosen and analyzed.
The accuracy of pedicle screw insertion was significantly increased when using the navigation system, although the average operative time and correction rate was not significantly different from that with non-navigated surgery.
The navigation technique improves the accuracy of pedicle screw placement during scoliosis surgery without prolonging the operative time or decreasing the deformity correction effect. Copyright © 2016 John Wiley & Sons, Ltd.
对于外科医生而言，在脊柱侧弯患者中准确植入椎弓根螺钉是一项挑战。计算机辅助导航技术可能有助于提高螺钉置入的准确性，从而避免并发症。因此，本研究的目的是比较在脊柱侧弯患者中使用计算机辅助导航技术和传统徒手方法进行椎弓根螺钉置入的准确性及术后评估。
检索了PubMed、Cochrane和科学引文索引数据库。选择并分析了评估有无导航技术的脊柱侧弯患者椎弓根螺钉置入准确性及术后评估的体内对照研究。
使用导航系统时，椎弓根螺钉植入的准确性显著提高，尽管平均手术时间和矫正率与非导航手术无显著差异。
导航技术可提高脊柱侧弯手术中椎弓根螺钉置入的准确性，且不延长手术时间或降低畸形矫正效果。版权所有© 2016约翰威立国际出版公司。
