摘　　要：目的：探讨经后路伤椎椎弓根钉固定治疗胸腰椎骨折的临床疗效及安全性。方法对48例胸腰椎骨折患者采用经后路伤椎椎弓根钉固定，根据情况行椎板切除减压术，均行横突间植骨融合治疗。术后随访1年，比较患者术前、术后3个月以及术后1年伤椎椎体压缩率及Cobb角的变化，评价术后复位情况。结果48例患者术后3个月及术后1年的术后伤椎椎体压缩率均较术前明显减小（P＜0．05）；术后3个月及术后1年的Cobb角均较术前明显缩小（P＜0．05）。复查X线片显示所有骨折均获得良好复位，内固定均无松动或断裂，无脊柱后凸畸形发生，神经功能均有1～3级恢复。结论经伤椎椎弓根钉固定治疗胸腰椎骨折具有固定可靠，复位效果好的优点。Objective To investigate the injury posterior vertebral pedicle nail fixed treatment of thoracolumbar fractures of the clinical efficacy and safety .Methods Forty-eight cases of thoracolumbar fractures were treated by the posterior vertebral pedicle screw fixation ,according to cases decompressive laminectomy ,underwent intertransverse fusion treatment .Postoperative follow-up of 1 year ,preoperative ,postoperative 3 months ,after 1 years of vertebral compression rate ,Cobb Angle were compared .Results Forty-eight patients with postoperative 3 months and 1 year after injury postoperative spinal vertebral body compression rate were significantly decreased compared with preoperative （P〈0 .05）;After 3 months and 1 year after the Cobb Angle were markedly sig-nificant reduction than preoperative（P〈0 .05） .X-ray showed all fractures were obtained good reduction ,internal fixation with no looseness or breakage ,no protruding after spinal deformity ,neural function were all in 1 -3 level recovery .Conclusion Posterior vertebral pedicle injury by nail fixed treatment of thoracolumbar fractures with fixed reliable ,reset effect is good .
