AF系统治疗胸腰椎骨折60例

AF System For Thoracolumbar Fracture CReport of 60 Cases

目的:探讨AF系统手术治疗胸腰椎骨折的疗效。方法:回顾以AF椎弓根系统手术治疗的胸腰椎骨折60例,分析了术后功能、并发症、伤椎及其相邻椎间隙的矫正与矫正丢失。结果:ASIA神经功能5级分度,恢复2个级差27例,1个级差33例;与正常椎相比较,伤椎高度平均矫正95.1%,远期矫正丢失为19.7%,伤椎相邻椎间隙变窄,上间隙较重。结论:AF系统治疗胸腰椎骨折对于伤椎高度、神经功能的恢复是肯定的,但存在内植材料断裂、矫正丢失等问题,未充分植骨与及时取出内植材料是其主要原因。

Objective：To assess the efficacy of AF system on thoracolumbar fracture. Methods： In 60 cases of thoracolumbar fracture treated with AF pedicle system, the postoperative function, complications, correction or correction loss between involved vertebrae and adjacent vertebrae were retrospectively analyzed. Results：27 cases improved 2 ASIA grades, 33 ones improved 1 ASIA grade. The rate of correction in height of involved vertebrae was 95.1%, the rate of correction loss in long - term was 19.7 %. The intervertebral space of involved verte- brae narrowed, specially superior one. Conclusion： AF system is effective in treatment of thoracolumbar fracture, recovery of height of inoolved vertebrae and nerve function. There are problems including implant rupture and correction loss, deficiency of bone grafting and delayed implant removal are the major causes.
