改良后入路环椎管减压AF内固定治疗胸腰椎爆裂骨折

目的:探讨胸腰椎爆裂骨折的最佳治疗方式。方法:根据骨折类型不同,采用后入路不同方式的环椎管减压AF内固定治疗胸腰椎爆裂骨折145例。结果:140例得到随访,平均随访34mo(3~80mo)。术前后凸成角平均26°,术后平均9;°术前椎管狭窄率平均54%,术后平均10%。136例获得Frankel分级1~3级以上的改善。结论:改良后入路环椎管减压AF内固定治疗胸腰椎爆裂骨折具有创伤小、出血少、操作简便、减压彻底、复位满意、固定可靠、植骨方便等诸多优点,可做为治疗新鲜胸腰椎爆裂骨折的首选术式。

POSTERIOR IMPROVED CIRCLE SPINAL CANAL DECOMPRESSION AND INTERNAL FIXATION WITH AF SYSTEM FOR THORACOLUMBAR BURSTING FRACTURES

Objective:To research a better operative method for thoracolumbar bursting fractures(TLBF).Methods:According to the distinction of fracture's types,145 patients with TLBF received posterior improved circle spinal canal decompression(PICSCD) and fixation with AF system.Results:140 cases had been followed-up for an average of 34 months(3~80 months).The preoperative average kyphosis angles was 26 degrees,and the postoperative average was 9 degrees.The spinal stenosis was notably improved.136 patients had improved nervous function by one grade or more according to Frankel's grading.Conclusion:PICSCD and internal fixation with AF system for TLBF has advantages of less injury,less bleeding,simple manipulation,thorough decompression,satisfied reduction,reliable fixation, convenient bone grafting,etc.It is the first choice for the treatment of TLBF.
