What exactly is a sequestrated lumbar intervertebral disc?
2 doctors weighed in across 2 answers
HNP: A sequestrated lumbar disc refers to migration of the central nuclear disc material through the outer layers that make up the anulus fibrosis and are then lodged in the spinal canal. Separation of the fragment from the disc from which it originates results in a sequestered fragment.

Separated: There are different degrees of herniation. The most severe degree is sequestered. It just means a piece of disc has ruptured through the back wall of the disc into the nerve canal and then migrated away to the extent it is no longer in contact with the disc.
