【摘要】：目的分析新型导引通道辅助经皮椎弓根置钉治疗无神经损伤胸腰椎骨折的手术时间、射线暴露时间及置钉准确性。方法收集2010年7月至2012年10月采用新型导引通道辅助经皮椎弓根置钉技术治疗的35例无神经损伤胸腰椎骨折患者临床资料,同一术者共完成178枚椎弓根螺钉置钉。记录分析每枚椎弓根螺钉置入时间及术者射线暴露时间,根据术后连续2次手术节段CT扫描结果,对置钉准确性进行分级和评估。结果本组置钉技术成功率为100%。单枚椎弓根螺钉平均置钉时间为(11.35±2.82)min,平均射线暴露时间为(8.06±2.15)s;156枚(87.64%)螺钉评定为A级,20枚螺钉(11.24%)为B级,1枚螺钉(0.56%)为C级,1枚螺钉(0.56%)为D级。结论新型导引通道有助于辅助经皮椎弓根置钉过程中定位穿刺点,提高置钉准确性,明显减少置钉时间及射线暴露时间。
[Abstract]:Objective to analyze the operative time of a new type of guided channel assisted percutaneous pedicle screw for the treatment of thoracolumbar fractures without nerve injury. Methods from July 2010 to October 2012, 35 patients with thoracolumbar fracture without nerve injury were treated with a new guidance channel assisted by percutaneous pedicle screw insertion. A total of 178 pedicle screws were placed in the same operation. The insertion time of each pedicle screw and the radiographic exposure time of each pedicle screw were recorded and analyzed. The accuracy of nail placement was graded and evaluated. Results the success rate of screw placement technique was 100. The average nail placement time of a single pedicle screw was 11.35 卤2.82 min, and the mean radiographic exposure time was 8.06 卤2.15 / s (156) screws were assessed as grade A, 20 screws and 11.24%, respectively. Conclusion the new guiding passage is helpful to locate the puncture point in the process of percutaneous pedicle screw insertion. Improve the accuracy of nail placement, significantly reduce the nail placement time and radiation exposure time.
