目的：探讨胸腰椎骨折应用经皮后路单节段椎弓根钉内固定治疗的临床效果。方法对15例压缩性骨折和轻度暴力骨折采用经皮后路单节段椎弓根钉内固定。患者随访6~24(平均16)个月,进行临床Denis疼痛评分、椎体前缘高度矫正率、后凸Cobb's角矫正率,调查患者手术满意度。结果所有患者均得到随访,所有患者均对手术表示满意。按照Denis疼痛分级,P1级有12例患者无疼痛,P2级有3例患者有轻微疼痛,无需服药治疗,神经功能均恢复至正常；X线检查术后椎体高度恢复满意,术后伤椎高度矫正率为95%、后凸Cobb's角矫正率为98%。无内固定物断裂、松动、脱出,所有病例均获得骨性愈合。结论选择好适应证,经皮后路单节段椎弓根钉内固定治疗胸腰段骨折能达到理想的疗效。“,”Objective To evaluate the clinical outcome of percutaneous injured vertebra pedicle screw fixation for thoracolumbar fracture. Methods 15 compression fracture and mild burst fracture patients treated by minimal yInvasive percutaneous injured vertebra pedicle screw fixation were fol owed up for 6to 24 months (average 16 months). The Denis pain scale, anterior vertebral height cor ection rate, kyphosis Cobb's angle cor ection rate and patients' satisfaction were recorded.Results Al patients were fol owed up and had a high level of satisfaction with surgery. According to Denis pain grading, 12 patients had no pain, 3 patients with occasional pain but no medication. X-ray evaluation revealed satisfactory recovery of vertebral body height, the anterior vertebral height cor ection rate was 95%, and the kyphosis Cobb's angle correction rate was 98%. No implant break, and no signs of pseudoarthrosis were observed.Conclusion The treatment for thoracolumbar fracture by percutaneous injured vertebra pedicle screw fixation isef ective with a proper indication.
