More than 75 percent of disk herniations occur below T8. The peak is at T11-12 where there is greater spinal mobility. Central protrusions are the mast common.
Okada Y, Shimizu K, Ido K, Kotani S (1997) Multiple thoracic disc herniations: case report and review of0the literature. Spinal Cord, 35: 182-186. <now I see the title only talks about T-spine herniations. While I didn’t read the original study, since the page quoting doesn’t explicitly say that it concerns only the T-spine etc etc as such, I guess the study is invalid for the subject. Sorry>
Can anyone explain why is it ok to flex and rotate the T-Spine but not the lumbar?
