【摘要】 目的　经前路应用AO自锁Ventro Fix脊柱内固定系统治疗胸腰椎爆裂骨折 ,前瞻性研究其坚强内固定的作用及价植。方法　采用经胸膜外—腹膜后入路 ,对 2 4例胸腰椎爆裂骨折患者行前路彻底减压 ,取髂骨椎间植骨 ,Ventro Fix脊柱内固定系统复位、内固定术。结果　 2 4例患者获 5～ 40个月随访 ,平均 16 7个月。椎间植骨融合均获成功。融合时间平均 3 8个月。除 2例患者外 ,Frankel分级均有一级以上改善 ,平均增加 1 5级。椎管占位面积术前平均 6 5 5 % ,术后椎管无占位。术前后凸成角 11～ 37° ,平均 2 4°,术后 4°。随访期间未见畸形复发或加重 ,也未见内固定松动、脱落及断裂现象。但有一例内固定螺钉自终板穿入椎间隙 ,所幸未造成负损伤。结论　经前路手术减压直接彻底 ,可获得神经功能最大改善。Ventro Fix脊柱内固定系统设计科学、合理 ,具备高度的内在稳定性。操作工具使用简便、可靠。内固定材料钛合金制造 ,生物相容性好 ,不必二次手术取出。是治疗胸腰椎爆裂骨折一种可靠有效的前路自锁内固定系统更多还原

【Abstract】 Objective To study anterior decompression and stabillization with the AO Ventro FIX in anterior decompression and fixation for thoracolumbar burst fractures Methods Twenty four patients with thoracolumbar burst fracture treated by anterior decompression,iliacbone grafting and AO Ventro Fix Fixation were followed Results The average followed up period was 16 7 months (5～40 months) The average posterior prominence angle was 24° before operation, and 6° after operation All patients had successful fusion with an average 3 8 months The nervous funtion of 22 cases had improved by one grade or more according to Frankels grading One fixing screw penetrated through disc, but no problem Conclusion Anterior decompression is directive and completely, so the greatest improvement of nerve function can be obtained AO Ventro Fix could supply high intrinsic stability, and is simple, safe and good biocompatible It is a kind of reliable anterior locking fixation system for thoracolumbar burst fracture更多还原
