The charts and roentgenograms of 200 patients operated upon for lumbar disc herniations were reviews. Among them, there were 42 persons in whom a lumbosacral transitional vertebra existed. The discs beneath these vertebra varied in appearance. A descriptive classification for the four disc types is proposed. In none of the 42 patients were there myelographic evidence of herniation of such a disc. In five instances, such disc were surgically inspected, and no protrusion was uncovered. Before transitional discs are operated upon, the proof of herniation should be incontrovertible.
对200例行腰椎间盘突出症手术患者的图表和X线片进行了回顾。其中，有42人存在腰骶部移行椎。这些椎体下方的椎间盘外观各异。提出了四种椎间盘类型的描述性分类。42例患者中均无此类椎间盘突出的脊髓造影证据。在5例中，对这类椎间盘进行了手术检查，未发现突出。在对移行椎间盘进行手术之前，椎间盘突出的证据应确凿无疑。
