摘要 目的 探讨后路复位联合椎弓根内固定系统治疗严重胸腰椎骨折脱位的疗效. 方法 对2007年6月至2012年6月治疗的16例严重胸腰椎骨折脱位患者资料进行回顾性分析,男13例,女3例;年龄17~47岁,平均33.6岁;损伤部位:T7-81例,T10-112例,T11-12 3例,T12至L15例,L1-2 3例,L3-42例.术前脊髓神经功能按美国脊髓损伤协会(ASIA)分级:A级6例,B级5例,C级4例,D级1例.所有患者均采用后路复位联合椎弓根螺钉系统进行复位与固定,并进行彻底的椎管前后减压、椎间和/或后外侧植骨融合. 结果 所有患者术后均获随访,时间18 ~ 69个月(平均35个月),手术时间为120~280 min(平均170 min);出血量为450 ~1 300 mL(平均700 mL).脱位椎体滑脱程度由术前72%±20%(56% ~100%)恢复至术后10%±6%(0~15%),脱位节段畸形角度由术前29.2°±15.0°(6°~51°)恢复至术后12.6°±6.7°(8°~18°),差异均有统计学意义(P<0.05).6例ASIA分级A级患者术后1例恢复至B级,1例恢复至C级,4例无明显恢复;5例B级患者3例恢复至C级,2例恢复至D级;4例C级2例恢复至D级,其余2例及1例D级患者恢复至E级.植骨均获骨性融合,无内固定物松动、断裂等并发症发生. 结论 对于严重胸腰椎骨折脱位患者,可通过后路椎弓根系统实现严重椎体骨折脱位的良好复位与固定,单纯后路可完成椎管的充分减压和植骨融合.
