Measurements of disc thickness, shape and degeneration, using the criteria described by Rolander (1966), were recorded from 204 post-mortem lumbar spines. The "true average disc height" increased with age as the discs "sink" into the vertebrae. These results add information to previous studies which indicate that the loss of transverse trabeculae of lumbar vertebrae is primarily responsible for the change in shape of both vertebrae and discs in the elderly. While the incidence of disc degeneration does increase in old age, the majority of the discs examined did not show evidence of any such change.
使用罗兰德（1966年）描述的标准，对204个尸检腰椎的椎间盘厚度、形状和退变情况进行了测量。随着椎间盘“下沉”到椎体中，“真正的平均椎间盘高度”随年龄增长而增加。这些结果为先前的研究增添了信息，先前研究表明，腰椎横向小梁的丧失是老年人椎体和椎间盘形状改变的主要原因。虽然椎间盘退变的发生率在老年时确实会增加，但大多数检查的椎间盘并未显示出任何此类变化的迹象。
