腰骶部移行椎与椎间盘突出症关系探讨

The relationship between lumbosacral transitional vertebra and the lumbar disc herniation

通过对２００例下腰痛患者及７８例经手术证实的腰椎间盘突出症的Ｘ线学调查，发现在下腰病和椎间盘突出症中腰椎部移行椎的发生率高，按Ｃａｓｔｅｌｌｖｉ分类，Ⅱ型最多，在有移行谁的椎间盘突出症中。７０％的椎间盘突出发生在移行椎的上一间隙，脊柱侧弯也明显多于无移行椎的对照组，髂嵴间线的高度在Ⅱ型中倾向较低．我们认为腰骶部移行椎从多方面影响脊柱的稳定。是引起下腰痛和椎间盘突出的一个因素。

cases of lumbago and 78 cases of lumbar disc herniation were analyzed in this paper. The incidence of the lumboaxcral transitional vertebra was high. The type Ⅱ of Castellvi's standard was the most compsen one. In the group of lumbar disc herniation with the transitional vertebra, there are 70% of lumbar disc her4iation occurred at the upper one disc of the transitional vertebra, and the scoliosis is much more thAn in the normal group. The intercrestal line tend to lower in the type Ⅱ. It was believed that the lumbosacral transitional vertebra induce the instability of spine and it is associated with the lumbago and the lumbar disc herniation.
