The Leiden case material of 6,565 protruded/herniated discs is analyzed with regard to age and localization. It appears that a positive correlation exists between these two parameters: in advancing age the protruded disc shows an apparent shift in localization to higher lumbar levels, the incidence of its localization at the L5-S1 level decreasing markedly at the same time.
对莱顿的6565例椎间盘突出/脱出病例资料进行了年龄和部位方面的分析。结果显示这两个参数之间存在正相关：随着年龄的增长，突出的椎间盘在部位上明显向更高的腰椎水平转移，同时其在L5-S1水平的发生率显著降低。
