AF内固定系统治疗胸腰椎骨折

目的 探讨应用AF系统治疗胸腰椎骨折的方法和临床疗效。方法 对我院2001年3月．2006年3月采用该方法治疗胸腰椎爆裂性骨折的21例患者的临床资料进行回顾性分析。结果 21例患者术后获随访3—20个月。平均8个月；伤椎前缘高度及Cobb＇s角均较术前改善（P〈0．01）。神经功能按Frankel分级：A级4例，术后3例无恢复；B—D级病人均有1-2级恢复。结论 应用AF系统治疗胸腰椎骨折可获满意的脊柱矫形、良好的椎管减压和神经功能恢复的疗效。

Treatment of thoracolumber vertebrae fracture with atlas fixation

Objective To explore the effectiveness (outcome) of the thoracolumbar vertebrae fracture with Atlas Fixation(AF) system.Methods A total of 21 patients with fracture of thoracolumbar spine were operated by AF internal fixation ,and the date of all the cases were retrospectively analysed.Results All patients were followded up for 3~20 months to observe the treating result.The average follow-up was 8 months.The anterior edge height decreased,and the Cobb's angle increased,there was a significant difference(P<0.01)compared with the pre-operative radiographic evaluation.4 cases who were A grade according to Frankel's criteria of calssificationhad no recovering,except one.The patients of B-D grade recoverd by1~2grade .Conclusion The atlas fixation (AF) is a good and reliable method to treat patients with thoracolumbar vertebrae fracture.
