目的 探讨分析经椎弓根植骨和钉棒固定在治疗胸腰椎骨折中的临床价值.方法 回顾分析94例患者的临床资料,所有病例均采用经后路椎弓根植骨、钉棒固定并结合椎管减压予以治疗.并于术前、术后即刻及后续的随访中行X线、CT及MRI检查,测量并比较患者伤椎椎体前后缘压缩率、Cobb角,并观察神经功能、脊柱活动度等的恢复情况.结果 手术顺利,术后切口无感染.术后即刻及末次随访时影像学检查结果显示患者伤椎椎体前后缘压缩率、椎管侵占平及Cobb角均较术前有明显改善(P＜0.05);术后各随访时间点间比较差异无统计学意义(P＞0.05).结论 经椎弓根植骨、钉棒固定治疗胸腰椎骨折在维持椎体高度,促进骨愈合,重建脊柱稳定性中取得了良好的临床疗效,并有效减少远期椎体塌陷及椎弓根钉断裂的发生.%Objective To analyze the clinical value of the pedicle bone graft and pedicle screw fixation in the treatment of thoracolumbar fractures.Methods To retrospectively analyze the clinical data of 94 patients.all patients were treated by posterior pedicle bone graft and pedicle screw fixation and be treated with decompression.X ray.CT and MRI should be down at the time of preoperative, immediate postoperative and follow-up. Measuring and comparing with vertebral and anterior vertebral compression rate and the Cobb angle of injury vertebral devices patients.and observing the neurologic and spinal recovery of activity,etc.Results Successful surgery,postoperative wound was not infected.Immediately after surgery and last follow-up imaging studies showed that vertebral compression,spinal canal encroachment rate and the Cobb angle improved compared with before surgery significantly(P＜0.05).Various times after the operation showed no significant difference in follow-up results(P＞0.05).Conclusion Pedicle graft,pedicle screw fixation for thoracolumbar vertebral fractures are highly conducive to the maintenance and promote bone healing and reconstruction of spinal stability, and effectively reduce the frequency of the long-term vertebral fracture collapse and pedicle screw.
