AF系统在胸腰段脊椎骨折中的应用

目的探讨AF内固定系统在治疗胸腰段脊柱骨折的临床应用。方法19例爆裂性骨折伴继发性椎管狭窄病例采用撑开内固定加全椎板切除减压，18例压缩性或爆裂性骨折无椎管狭窄病例采用单纯撑开内固定。结果全部病例均获随访，平均随访1年8个月，骨折均愈合。3例椎体高度丢失10—15％，术后腰痛2例，无1例镙钉松动、断裂。结论AF系统是治疗胸腰段单个椎体骨折较理想的内固定材料，但应掌握好手术适应证和椎弓根镙钉植入技巧，并进行良好的复位。

Objective To discuss AF fixation system in the treatment of thoracolumbar spine fractures clinical application. Methods 19 cases of burst fracfure with secondary spinal canal stenosis cases using distraction within fixed and Canada decompressive laminectomy. 18 cases of compression or a burst fracture patients without spinal stenosis using simple distraction fixation. Results All patients were followed up for an awerage of one year and eight months, the fracture heated. 3cases of vertebral height loss of 10 - 15% , two cases of low back pain. But no one screw lovsening, fracture. Conclusion AF system is a single treatment of thoracolumbar vertebrae fractures than ideal internal fixation devices, but should have a good indication for surgery and pedicle screw implants skills, and good reduction
