To study the value of the classification of the elderly lumbar disc herniation(LDH) as an indication of microendoscopic discectomy(MED).
Based on the pathological features of the elderly LDH, eighty-one patients over fifty years old (Group A) were proved to be intraspinal complications by traditional operation and were divided into I and II types which were compared with what were seen in the operation. Sixty-two patients over 50 years old (Group B) were treated with MED and reviewed retrospectively, and their curative effects were compared with their types.
A general intraspinal narrowness rate of Group A was 62.07% in Type I, 107.69% in Type II (P < 0.01). Group B was all followed up (mean 10 months). According to the macnnab criterion, the satisfactory rate was 100% in Type I, 75% in Type II (P < 0.05).
The clinical classification of the elderly LDH makes a significant effect on the treatment of MED, can be used as an indication of MED, and can be popularized in clinic.
探讨老年腰椎间盘突出症（LDH）的分类对微创椎间盘切除术（MED）的指导价值。
根据老年LDH的病理特点，选取81例50岁以上患者（A组），经传统手术证实存在椎管内并发症，并分为Ⅰ型和Ⅱ型，与术中所见情况进行对比。回顾性分析62例50岁以上接受MED治疗的患者（B组），比较其疗效与分型情况。
A组椎管狭窄总发生率Ⅰ型为62.07%，Ⅱ型为107.69%（P<0.01）。B组均获随访（平均10个月）。按Macnab标准，Ⅰ型优良率为100%，Ⅱ型为75%（P<0.05）。
老年LDH的临床分型对MED治疗有重要指导作用，可作为MED的手术指征，值得临床推广。
