经伤椎置椎弓根钉内固定治疗胸腰椎椎体骨折脱位36例临床观察

目的探讨经伤椎置椎弓根钉内固定治疗胸腰椎椎体骨折脱位36例临床疗效。方法选取2009年1月～2010年12月本院收治的36例胸腰椎椎体骨折脱位患者,经过经伤椎置椎弓根钉内固定手术治疗,并对其进行回顾性分析。结果经研究发现患者术后Cobb角、伤椎椎体前缘高度恢复良好,术后12个月与术后1个月相比无明显差异。结论经伤椎置椎弓根钉内固定治疗胸腰椎椎体骨折脱位,可使伤椎椎体高度得以恢复,尤其是伤椎椎体前缘高度的比值得到改善,Cobbs角改善明显,术后并发症也明显减少,效果满意。

Clinical observation on pedicle screw fixation by injured vertebra in 36 cases of thoracic and lumbar vertebral fracture and dislocation

Objective To study the clinical effect of pedicle screw fixation by injured vertebra in 36 cases of thoracic and lumbar vertebral fracture and dislocation. Methods Thirty six patients with thoracic and lumbar vertebral fracture and dislocation in our hospital from January 2009 to December 2010 were treated with pedicle screw fixation by injured vertebra, then they were retrospectively analyzed. Results The cobb angle and the front height of injured vertebra of patients recovered well,these items after the surgery at twelfth month had no significantly differences to those at first month. Conclusion The treatment of pedicle screw fixation by injured vertebra in thoracic and lumbar vertebral fracture and dislocation can regain the vertebral height of injured vertebra, the ratio of front height of injured vertebra is especially improved, cobb angle is significantly improved, complication is significantly decreased, the effect has satisfactory results.
