AF内固定系统治疗胸腰椎骨折72例疗效观察

Observation on curative effect of AF internal fixation system in treatment of thoracolumbar fracture in 72 cases

目的探讨AF内固定系统治疗胸腰椎骨折的方法和临床疗效。方法应用AF内固定系统治疗72例胸腰椎骨折,观察手术前后神经功能、椎体高度、矢状指数的变化及并发症发生的情况。结果神经功能改善有效率86.1%,椎体前后缘高度恢复正常91.7%,矢状指数由术前5°～31°(平均18°),恢复到术后-5°～6°(平均0°),发生螺钉植入错误、断钉、断杆等并发症各1例,占4.2%,未发生神经血管并发症。结论应用AF内固定系统治疗胸腰椎骨折疗效可靠,安全性较高,正确选择AF器件和熟练的操作是手术成功的关键。

[Objective] To explore the methods and clinical effects of AF internal fixation system used in the treatment of thoracolumbar fracture. [Methods] AF internal fixation system was applied to treat thoracolumbar fracture in 72 cases. Neurological function, vertebral body height, sagittal index（SI） and the complications were observed and recorded perioperatively. [Results] The effective rate of the neurological function recovery was 86.1%. The vertebral body height recovered to 91.7%.SI improved from 18°（5°-31°）to 0°（-5°-6°） in average. The hardware failure rate was 4.2%, and no neurovascular complications existed. [Conclusion] AF internal fixation system can be applied to treat thoracolumbar fracture with reliable curative effect and high security. The correct selection and skilled manipulation of AF device are crucial to successful operation.
