Twenty-nine fragments from herniated lumbar discs of patients over 60 years of age were studied pathohistologically. For comparison, 109 discs from patients under 59 years of age also were observed. They were classified into seven types according to their composition. In 70% of discs from patients between 60 and 69 and in 80% of discs from patients over 70, the fragments were composed of the anulus fibrosus and the cartilaginous end-plate. The authors concluded that the cartilaginous end-plate had avulsed from the vertebral body and herniated with the anulus fibrosus in these cases. This type of herniation occurs more often than herniation of the nucleus pulposus over 30, and may be most common in elderly patients because of their advanced disc degeneration.
对29例60岁以上患者的腰椎间盘突出碎片进行了病理组织学研究。作为对照，还观察了109例59岁以下患者的椎间盘。根据其组成将它们分为七种类型。在60至69岁患者的70%的椎间盘中，以及在70岁以上患者的80%的椎间盘中，碎片由纤维环和软骨终板组成。作者得出结论，在这些病例中，软骨终板已从椎体撕脱并与纤维环一起突出。这种类型的突出比30岁以上的髓核突出更常见，并且由于老年患者椎间盘退变严重，可能在老年患者中最为常见。
