The lumbar intervertebral foramens of 20 isolated cadaveric spines were investigated by the use of a molding technique to assess their dimensions accurately and how intervertebral disc pathology altered their configuration. Oval foramens predominated over auricularly shaped foramens when the disc was normal, but when the disc was abnormal, the converse was true. Foraminal size varied from 40 to 160 mm2 but showed great variation even at individual levels; these were not accurately reflected by simple radiologic measurements.
使用一种成型技术对20个离体尸体脊柱的腰椎椎间孔进行了研究，以准确评估其尺寸以及椎间盘病变如何改变其形态。当椎间盘正常时，椭圆形椎间孔比耳形椎间孔更为常见，但当椎间盘异常时，情况则相反。椎间孔大小在40至160平方毫米之间变化，即使在个体水平上也存在很大差异；简单的放射学测量并不能准确反映这些差异。
