钉棒系统内固定治疗胸腰椎骨折45例

Internal fixation by nail-stick system in treat ment of 45 cases of thoracolumbar fracture

目的探讨钉棒系统内固定治疗胸腰椎骨折的临床疗效。方法45例胸腰椎骨折患者均给予钉棒系统内固定手术治疗，记录患者不同时间段伤椎前缘高度与正常椎前缘高度比值变化情况、脊柱后凸Cobb角变化情况，将所得资料进行统计学分析。结果经钉棒系统内固定手术治疗1周后伤椎前缘高度与正常椎前缘高度比值、脊柱后凸Cobb角均较治疗前显著改善（P〈0．05）；随访1年后患者伤椎前缘高度与正常椎前缘高度比值、脊柱后凸Cobb角较手术1周后无明显丢失（P〉0．05）。结论胸腰椎骨折患者采用钉棒系统内固定技术治疗可获得满意疗效及预后，，临床医生应准确掌握此法适应证，对符合条件的患者尽快实施外科手术治疗，以保障患者生活质量。

Objective To investigate the effect of internal fixation by nail-stick system on thoracolumbar fracture. Methods Forty-five eases of thoracolumbar fracture patients were given the internal fixation by nail-stick system, leading edge of vertebral height in pa- tients with normal vertebral anterior height ratio changes, kyphosis Cobb angle changes were recorded and statistically ana- lyzed. Results After treatment for one week, the vertebral height and the leading edge of the front edge of the normal ver- tebral height ratio, and kyphosis Cobb angle were significantly improved than that before treatment （ P 〈 0. 05 ）. After 1 year follow-up, the indicators above had no significant loss （P 〉 0.05）. Conclusions Internal fixation by nail-stick sys- tem for treating thoracolumbar fracture is effective and has satisfactory outcome and prognosis. Clinicians are expected to be well known about this method to improve the quality of life of patients.
