后路钉棒系统治疗胸腰椎骨折及脱位50例临床观察

Clinical observation of posterior nail bar system in the treatment of thoracolumbar fractures and dislocations

目的探讨后路钉棒系统治疗胸腰椎骨骨折及脱位的手术疗效。方法对2009年3月至2010年12月夏邑县人民医院骨科收治的50例胸腰椎骨折及脱位患者的临床资料进行回顾性分析。结果术后50例切口均全部愈合，无切口感染、血肿或脑脊液漏并发症。经X线检查，无内固定材料松动或断裂及胸腰椎移位或骨折。螺钉均准确地经过椎弓根，固定位置良好且牢固。全部患者进行随访，回访时间为6个月～1年。结论应用后路钉棒内固定系统治疗胸腰椎骨折及脱位，使得椎体前缘高度及脊柱的弯曲得以重新建立，固定良好且复位准确，疗效显著，在临床上值得进一步推广应用。

Objective To investigate the effect of posterior screw-rod system on thoracolumbar fractures and dislocations. Methods The clinical data of 50 patients with thoracolumbar fracture and dislocation admitted in our department from March 2009 to December 2010 were retrospectively analyzed. Results Postoperative wounds were all healed, no wound infection, hematoma, or cerebrospinal fluid leak age. By X-ray examination, no loose fixation of thoracolumbar fracture or displacement or fracture. The pedicle screws were accurately fixed position good and solid. All patients were followed-up for 6 months to 1 year. Conclusions By application of posterior screw-rod fixation for thoracolumbar fractures and disloca- tion, anterior vertebral height and spinal curvature can be re-established, not only with good and reset fixed accuracy, the effect is good, and worthy to be further clinical applicated.
