摘要
[目的]评价PLIF治疗复发性腰椎间盘突出症的临床疗效并探讨复发性腰间盘突出症的原因。[方法]2011年1月~2015年12月,我科收治的32例复发性腰间突出症患者,均采用PLIF再手术治疗,32例均获得随访,随访时间为8~48个月(平均16.1个月)。对术前、术后分别进行JOA评分系统评分评定治疗效果,根据X线评价植骨融合情况。[结果]所有病例6个月复查均获得骨性融合,术后根据JOA评分,术前JOA评分平均8.6分,术后随访时JOA评分平均25.6分,平均改善率83.3%。[结论]初次手术处理不当及术后腰椎病变节段生物力学和解剖结构的改变是间盘突出复发的主要原因。PLIF解决彻底减压和重建腰椎稳定后,获得了良好的临床疗效。
[Objective]To evalue the clinical outcoming of recurrent lumbar disc herniation(RLDH) treated by PLIF and investigate the etiology of RLDH.[Method]32 cases with RLDH operatedby the approoach PLIF during January 2011 to November 2014, were followed up. JOA system was used for evaluation of clinical outcoming before operation and during follow-up period, and X-ray oflumbar spine was performed postoperatively. The patients were followed up for 8 ~ 48 months, average 16.1 months.[Result]All cases obtained bone fusion after 6 postoperative months, and accordingthe score of JOA,the average JOA score was 8.6 before operation, and 25.6 at follow-up. The recovery rate was 83.3 in average.[Conclusion]The improper treatment of the first time and change ofbiomechanics and anatomical structure of lumbar spine after surgery are the main causes of RLDH. RLDH operated by the approoach PLIF which deal with thorough decompression and reconstruct thestability of the lumbar spine can obtain better effects.
