经皮穿刺椎间盘摘除(APLD)是近年国外治疗椎间盘突出症的—种新方法,国内一些医院亦已开展这一术式。但L5～S1椎间盘周围结构复杂,较上位椎间盘有较大的差异,一些学者认为该平面不宜施行经皮闭式髓核摘除术。本文着重探讨经皮髂骨钻孔、腹前壁戳口两种入路的应用解剖。在24具成人标本上解剖观察了L_5～S_1椎间盘的毗邻关系。L_5～S_1椎间盘外侧存在一个由髂血管和神经围成的“V”相对安全区,在该 Percutaneous discectomy (APLD) is a new method of treating disc herniation abroad in recent years. Some hospitals in China have also carried out this procedure. However, the structures around the L5 ~ S1 intervertebral discs are complex and have more differences than those of the upper intervertebral discs. Some scholars think that this plane should not be performed percutaneous closed nucleus excision. This article focuses on the application of percutaneous iliac bone drilling, anterior abdominal wall of the two methods of application of anatomy. Twenty-four adult specimens were dissected to observe the adjacent relationship of L_5 ~ S_1 intervertebral disc. There is a “V” relative safety zone outside the L_5 ~ S_1 intervertebral disc in the iliac vessels and nerves,
