几位作者已经注意到，在腰椎间盘突出症患者的X线片中，腰骶椎先天性异常的频率很高。这些异常包括椎弓峡部裂、脊柱裂和骶骨化。奥康奈尔（1951）描述了另一种变异，即神秘的神圣化。骶骨位于骨盆的高处，最后一节腰椎的棘突可能与髂嵴齐平，或略低于髂嵴。腰椎有五个椎体，但骶骨可能由六个椎体节段组成。由于这些病例不是第五腰椎的明显骶化，因此术语“隐性骶化”被用来描述这种异常。人们认为，承认坦率和神秘的神圣化是重要的。首先，这两种情况可能使椎间盘突出;其次，神经系统症状和体征可能与粗略检查X线片所预期的不一致，也可能与手术所见不一致。本文的目的是首先比较的频率都坦率和隐匿性骶化的患者患有腰椎间盘突出症与对照系列。
THE frequency of congenital abnormalities of the lumbosacral spine in the radiographs of patients suffering from lumbar intervertebral disk protrusions has been noted by several authors. These abnormalities include spondylolysis, spina bifida, and sacralization. A further variation--namely, occult sacralization-has been described byO'Connell (1951). Here the sacrum is high in the pelvis, and the spinous process of the last lumbar vertebra may be level with, or just below, the iliac crests. The lumbar spine shows five vertebrz, but the sacrum may be composed of six vertebral segments. As these are not cases of frank sacralization of the fifth lumbar vertebra, the term'occult sacralization'has been used to describe the abnormality. It is believed that the recognition of both frank and occult sacralization is of importance. In the first place these two conditions may predispose to intervertebral disk protrusions; in the second place the neurological symptoms and signs may be at variance with those expected from a cursory examination of the radiographs, as well as with the findings at operation. The purpose of this paper is firstly to compare the frequency of both frank and occult sacralization in patients suffering from lumbar intervertebral disk protrusions with that in a control series.
