　　目的分析经伤椎椎弓根内固定植骨治疗胸腰椎爆裂性骨折的疗效。方法回顾性分析138例胸腰椎爆裂性骨折患者的临床资料。30例行4钉内固定植骨(A组)，108例行经伤椎椎弓根5钉固定同时植骨(B组)。术后随访22~72个月。结果术后及随访时，两组伤椎前缘高度、矢状面Cobb角、神经功能恢复改善，但两组之间无显著性差异(P>0.05)。随访时两组间腰背疼痛视觉模拟评分B组更低(P<0.05)。结论经伤椎椎弓根钉固定植骨术治疗胸腰椎爆裂性骨折能更有效地降低后期腰背疼痛。

Objective To investigate the clinical outcome of fixation and autograft through the pedicle of fractured vertebrae for thoraco-lumbar burst fracture. Methods 138 cases with thoracolumbar burst fracture were retrospectively analyzed. 30 cases (group A) accepted 4 pedicle screw fixation with autogrft, and other 108 cases (group B) accepted internal fixation through the pedicle of fractured vertebrae with autogrft. All the cases were followed up for 22~72 months. Results The fractured vertebral height and Cobb's angle recovered and the neuro-logical function improved after treatment in both groups (P<0.05), but there was no significant difference between 2 groups. There was sig-nificant difference in Visual Analogue Score for back pain (P<0.05). Conclusion Vertebral pedicle screw fixation with transpedicular auto-graft is an effective operation for thoracolumbar burst fracture, especially on back pain.
