目的：观察U PASS-Ⅱ脊柱微创系统经皮椎弓根螺钉内固定治疗胸腰椎骨折的临床疗效。方法2011年5月至2012年12月，应用U PASS-Ⅱ脊柱微创系统经皮椎弓根螺钉内固定治疗26例没有神经损害的胸腰椎骨折患者（观察组），并与同期收治的另外26例采用传统开放切口椎弓根螺钉内固定治疗的胸腰椎骨折患者（对照组）进行比较。结果所有患者均随访半年以上，平均9．2个月。虽然两组患者的Cobb′s角、椎体前缘高度、视觉模拟疼痛评分（VAS）、日本骨科学会下腰痛评分（JOA）和Oswestry 功能障碍指数（ODI ）等术后均有显著改善（P＜0．01），但是观察组的手术时间、住院时间显著短于对照组（P＜0．05），而且观察组的手术出血量和术后伤口引流量也明显少于对照组（P＜0．01）。结论本研究显示UPASS-Ⅱ脊柱微创系统经皮椎弓根螺钉内固定术治疗胸腰椎骨折，能够快速缓解疼痛，早期稳定受伤脊柱，却不牺牲任何脊柱的运动节段。

Objective To observe the therapeutic effects of UPASS-Ⅱ minimally invasive spinal system percutaneous pedicle screws internal fixation treating thoracolumbar fracture .Methods From May 2011 to December 2012 ,26 patients(observing group) were sufferred from thoracolumbar fracture without neural impairment were treated with UPASS-Ⅱ minimally invasive spinal sys-tem percutaneous pedicle screws internal fixation ,and were compared with other 26 cases(control group) adopted the treatment of conventional open pedicle screws internal fixation in the same period .Results All patients were followed up more than 6 months (mean 9 .2 months) ,the comparison of Cobb′s angle ,anterior vertebra height ,VAS ,JOA score and ODI between pre and post oper-ation were all significantly different in both group(P<0 .01) ,but the operation time and length of stay in the hospital in observing group were significantly shorter than that in control group (P<0 .05) ,moreover ,the amount of operative bleeding and drainage of post operation in observing group decreased obviously than that in control group (P<0 .01) .Conclusion This study shows that UPASS-Ⅱ minimally invasive spinal system percutaneous pedicle screw internal fixation treating thoraco-lumbar fracture is a safe and effective treatment strategy in selected patients .
