探讨腰椎间盘突出症与腰骶部横突异常的关系。我们回顾了连续200例腰椎间盘突出症脊髓造影术阳性的患者。患者(60例)表现为横突异常，以满足腰椎移行椎体的标准。本文根据突出髓核的形态和临床特点，提出了腰骶部移行椎体的新分类。I型代表腰骶部移行椎体的一种形式，在突出部位的发生率上没有差别。在III型和IV型中，腰椎移行椎体水平没有突出，腰椎移行椎体近端的突出发生率也没有增加。II型腰椎移行椎体在移行节段表现为腰椎间盘突出。它还显示腰骶部移行椎体上方的水平上的突出发生率高于正常水平。
The relationship between herniated lumbar disc and abnormalities of the transverse process of the lumbosacral junction was investigated. Consecutive patients (200) with positive myelographic findings of herniated lumbar disc were reviewed. Patients (60) presented abnormalities of the transverse process to satisfy the criteria for lumbosacral transitional vertebra. A new classification of lumbosacral transitional vertebra is presented based upon the morphologic and clinical characteristics with respect to herniated nucleus pulposus. Type I represents a forme fruste of lumbosacral transitional vertebra and shows no difference in the incidence of the location of herniations. In types III and IV, there are no herniations at the level of the lumbosacral transitional vertebra and no increase in the incidence of herniations just proximal to the lumbosacral transitional vertebra. The Type II lumbosacral transitional vertebra presents herniated lumbar disc at the level of transition. It also presents a greater than normal incidence of herniations at the level just above the lumbosacral transitional vertebra.
