目的 探讨腰椎间盘突出症术后原位复发的原因和腰椎后路椎间融合术(PLIF)的临床疗效.方法 11例原位复发性椎间盘突出症患者均采用手术治疗,初次行椎板间开窗髓核摘除术8例,椎间盘镜下髓核摘除术2例,臭氧消融术1例;再次手术采用腰椎后路椎间融合术.采用Oswestry评分进行术前和随访时的评分.结果 11例全部为原手术节段间盘脱出,再次手术平均历时3.2 h,术中出血平均450 ml,平均住院时间为13.3 d.患者再次手术前Oswcstry评分平均52.3分,术后随访时评20.3分,72.7% 的患者对手术疗效满意.结论 原位复发性椎间盘突出症采用腰椎后路椎间融合术手术治疗,同时解决腰椎减压和稳定,临床效果良好.“,”Objective To investigate the cause of recurrent herniation of lumbar disc and the outcomes of posterior lumbar of interbody fusion(PLIF).Methods A total of 11 cases with recurrent lumbar disc herniation were treated by PLIF.The primary operations was open window discectomy in 8 cases, microendoscopic discectomy in 2 cases,ozone marrow nucleus dissolution in 1 case.The second surgery of PLIF was performed in all cases with average time of 3.2 hours and blood loss of 450 ml.the patients were followed up and recived Oswestry scoring.Results All cases had recurrent disc herniation on the original operative sites.The average hospital stay after second operation was 13.3 days.Oswestry score was improved from 52.3 before to 20.3 after second operation and 72.7% cases had satisfactory surgical results.Conclusion PLIF for recurrent hernation of lumbar disc can deal with decompression and segmental fusion simultaneously with better outcomes.
