目的　通过对 7例儿童骨折脱位型腰段脊髓损伤的的诊断治疗分析 ,总结患儿受伤特点及内固定治疗的方法和经验。方法　回顾分析 7例急性腰椎骨折伴不完全脊髓损伤病例 ,男 5例 ,女 2例 ,年龄 6～ 1 2岁 ,平均 9岁。X线均呈明显腰椎骨折伴移位 ,按Frankel分级 ,B级 5例 ,C级 2例。采用后路减压内固定复位固定术。结果　经 8个月～ 4年 3个月随访 ,7例均恢复正常或接近正常 ,按Frankel分级提高 2～ 3级。结论　对于儿童不稳定腰椎损伤伴脊髓损害者非手术治疗无法复位并保持稳定应考虑及时采取手术治疗 ,采用精制内固定装置能有效减少创伤、重建脊柱的稳定性、促进损伤的脊髓功能恢复 Objective To analyze and analyze the diagnosis and treatment of lumbar spinal cord injury in children with fracture and dislocation of seven cases and summarize the characteristics of the injury and the methods and experience of internal fixation. Methods A retrospective analysis of 7 cases of acute lumbar fractures with incomplete spinal cord injury cases, 5 males and 2 females, aged 6 to 12 years old with an average of 9 years old. X-ray showed obvious lumbar fracture with displacement, according to Frankel classification, B grade in 5 cases, C grade in 2 cases. Posterior decompression with internal fixation and reduction fixation. Results After 8 months to 4 years and 3 months follow-up, all 7 patients returned to normal or nearly normal, and the grade was increased by 2 to 3 according to Frankel classification. Conclusion For patients with unstable lumbar spinal cord injury with spinal cord injury non-surgical treatment can not be reset and maintain stability should be taken timely surgical treatment, the use of refined internal fixation device can effectively reduce the trauma, reconstruction of the spine stability and promote spinal cord injury recovery
