Sequestrated Disc Definition

Sequestrated disc is a condition in which a portion of the vertebral disc fragments and migrates into the spinal canal. The condition results when the nucleus pulposus of a herniated disc extrudes through the annular fibers and a piece of the nucleus breaks free. The disc fragment can compress the spinal nerve root, causing pain and symptoms similar to herniated discs. Pain from a sequestrated disc can be treated conservatively or with spinal fusion surgery.
