椎间盘镜辅助下经皮椎弓根螺钉内固定治疗胸腰椎骨折

目的：探讨椎间盘镜辅助下经皮椎弓根螺钉内固定治疗胸腰椎骨折的疗效。方法：2009年2月-2011年7月,采用椎间盘镜辅助下经皮椎弓根螺钉内固定治疗胸腰椎骨折18例（微创组）,并与常规的开放手术组（15例）相比较。结果：两组病例的伤椎前后缘高度百分比、后凸Cobb’s角术前术后相比差异有统计学意义（P〈0.01）,两组间术后影像学观察指标比较差异无统计学意义（P〉0.05）。微创组较常规的开放组的切口长度、术中出血量、住院时间明显减少,（P〈0.01）,但手术时间两组比较差异无统计学意义（P〉0.05）。结论：椎间盘镜辅助下经皮椎弓根螺钉技术具有创伤小、出血少、术后恢复快等优点,是治疗胸腰椎骨折的有效方法。

Percutaneous Pedicle Screw Internal Fixation under Diskoscope in the Treatment of Thoracolumbar Fractures

Objective:To detect the feasibility of percutaneous pedicle screw internal fixation under diskoscope in the treatment of thoracolumbar fractures.Methods:Eighteen patients with thoracolumbar fractures were treated by percutaneous pedicle screw internal fixation under diskoscope(mini-trauma group),and 15 patients were treated by traditional open operation(traditional group) from Feb.2009 to Jul.2011.Results:The postoperative vertebral height and Cobb’s angle were significantly increased in both groups(P<0.01).The incision size,the blood volume of operation,and the hospital stay in mini-trauma group were significantly less than traditional group(P<0.01).But the operative time and indexes of postoperative iconography were not different in the two groups(P>0.05).Conclusion:Percutaneous pedicle screw internal fixation under diskoscope is effective for treating thoracolumbar fractures,which has some advantages such as mini-traumas,less blood lose and postoperative recovery quickly.
