In the presence of transitional lumbosacral segmentation, the lumbosacral intervertebral disc is significantly narrower than its counterpart in non-transitional spines. Even in spines with no transitional features, the lumbosacral disc is significantly narrower than discs at higher levels. This narrowing does not imply disc degeneration.
在存在过渡性腰骶部节段的情况下，腰骶椎间盘明显比非过渡性脊柱中的对应椎间盘更窄。即使在没有过渡特征的脊柱中，腰骶椎间盘也明显比更高节段的椎间盘更窄。这种变窄并不意味着椎间盘退变。
