Abstract: 【Abstract】〓Objective〓To investigate the efficacy of minimally invasive percutaneous pedicle screw fixation on thoracic vertebral compression fractures. Methods〓Thirty patients with thoracic vertebral compression fractures from January 2012 to November 2014 were included in the study, the data were analyzed retrospectively. Of these 30 cases, 15 underwent surgical procedure of minimally invasive percutaneous pedicle screw fixation (observation group) and 15 were treated with open surgery of traditional posterior midline longitudinal incision approach. The operation time, blood loss, hospital stay, postoperative visual analogue scale (VAS), postoperative Cobb angle correction rate, postoperative failed back surgery syndrome(FBSS) were compared between two groups. Results〓In observation group, the mean operation time, blood loss, hospital stay were significantly reduced when compared with control(P<0.05). VAS at 48 h was significantly lower in observation group than in control group(P<0.05). The postoperative Cobb angle correction rate in observation group was similar to that in control. FBSS patients in control group was higher than in the observation group, but the difference was not statistically significant. Conclusion〓Minimally invasive percutaneous pedicle screws osteosynthesis has better surgical results than the traditional posterior midline longitudinal incision approach in treatment of thoraco-lumbar vertebra fracture.

摘要： 【摘要】〓目的〓探讨经皮微创行椎弓根螺钉内固定治疗单纯胸腰椎压缩性骨折的临床疗效。方法〓选择2012年1月至2014年11月间我院收治的30例单纯胸腰椎压缩性骨折患者,分为对照组(n=15)和观察组(n=15)。对照组患者采用传统的以伤椎为中心的后正中纵行切口开放手术,观察组患者采用经皮微创椎弓根螺钉内固定手术。比较两组患者手术相关指标、术后48 h疼痛视觉模拟评分(VAS)、手术即期效果和远期效果、术后腰椎手术失败综合征(FBSS)的发生情况。结果〓观察组平均手术时间缩短,术中出血量明显减少,住院时间显著缩短(P<0.05);观察组术后48 h VAS也明显低于对照组为(P<0.05);两组患者术后局部Cobb角矫正率和末次随访局部Cobb角矫正率相似,说明两种手术方式的即期和远期效果相似。对照组患者术后FBSS发生率略高于观察组,但差异无统计学意义。结论〓微创手术创伤小,恢复快,不影响手术的矫正效果。
