经椎弓根钉固定治疗胸腰椎不稳定骨折疗效研究

目的：研究经椎弓根钉固定治疗胸腰椎不稳定骨折的疗效。方法选取我院2012年1月~2013年12月收治的55例胸腰椎不稳定骨折患者为研究对象,对其行经椎弓根钉固定治疗,对治疗前后Cobb角、Frankel分级等情况进行比较分析。结果术前患者平均Cobb角（21.1±0.5）o,平均Frankel分级（2.8±0.3）级,术后半年患者Cobb角（7.0±0.2）o,平均Frankel分级（4.8±0.2）级,两者比较差异有统计学意义（P〈0.05）。此外,术后随访1年55例患者未出现明显并发症。结论经椎弓根钉固定治疗胸腰椎不稳定骨折疗效显著,具有复位固定良好、操作简单、重建脊柱稳定等优点,可作为胸腰椎不稳定骨折的主要治疗手段。

Study on the curative effect of pedicle screw fixation in the treatment of unstable thoracolumbar fractures

Objective To explore the curative effect of pedicle screw fixation in the treatment of unstable thoracolumbar fractures. Methods All 55 patients with unstable thoracolumbar fractures who were admitted to our hospital from Jan-uary 2012 to December 2013 were selected as research subjects and received the treatment of pedicle screw fixation. The Cobb angle and Frankel grading before and after the treatment were compared and analyzed. Results Average Cobb angle before the surgery was（21.1±0.5）o, and the average Frankel grade was（2.8±0.3）. The Cobb angle in half an year after the surger was（7.0±0.2）o, and the average Frankel grading was（4.8±0.2）. The differences were statisti-cally significant（P〈0.05）. In addition,55 patients did not show obvious complications in a one-year follow-up. Con-clusion The pedicle screw fixation in the treatment of unstable thoracolumbar fractures has a significant effect and ad-vantages of good reduction fixation, easy operation and reestablishing spinal stability, so it can be applied as main treatment method for unstable thoracolumbar fractures.
