The measured height of the lumbosacral disc in patients with and without transitional vertebrae.
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.
