单节段复发性腰椎间盘突出症经后路椎间盘镜再手术疗效观察

目的:探讨LDH术后复发的原因以及应用后路椎间盘镜行再次手术的疗效。方法:应用后路椎间盘镜对31例LDH手术疗效差、术后复发的患者再次手术,行单纯扩大开窗或半椎板切除,并证实再次手术原因。结果:31例均获随访时间8～24个月。采用Nakai分级标准进行疗效评估,优18例、良8例、可3例,差2例。结论:只要诊断明确,严格掌握适应证,术中操作细致,则应用MED对单节段复发性LDH行单纯扩大开窗或半椎板切除再次手术是较理想的方法,并能使绝大多数病例获得满意疗效。

Single segment of recurrent lumbar disc herniation by posterior endoscopic discectomy observed under the effect of re-operation

Objective To explore the reasons for postoperative recurrence of lumbar disc herniation(LDH) as well as the application of mirror line posterior disc surgery again.Method Application of posterior disc on 31 cases of endoscopic surgery LDH poor in patients with postoperative recurrence of re-operation,the window to expand or semi-simple laminectomy,and confirmed that the reasons for re-operation. Results Thirty-one cases were followed up for 8～24 months.Nakai classification criteria was used to assess efficacy,18 cases of excellent,good in 8 cases,3 cases of ok,and 2 cases of poor.Conclusion As long as the diagnosis of clear,strict indications,during the operation carefully,the application of single segment MED recurrent LDH window line to expand or semi-simple laminectomy surgery again is a more ideal way to enable access to the vast majority of cases satisfied with the effect.
