What is a sequestered disc fragment?

A free fragment, also known as a sequestered disc, is one type of herniated disc in which a piece breaks off from the main structure. Once separated, the detached fragment can, and often does, move up or down, causing symptoms or repercussions at an entirely different level of the spine. Source: Verywell Health.

Does a sequestered disc require surgery?

We suggest conservative treatment in the initial course of the sequestrated type of disc herniation for at least 2 months before recommending surgical intervention unless severe neurologic deterioration takes place.

How do you treat a sequestered disc?

How is Disc Sequestration Treated? If disc extrusion or sequestration causes compression of nerves or spinal cord and there are symptoms, in most cases conservative treatment over several weeks will alleviate those symptoms. This includes pain medication, physical therapy, and other medical methods of treatment.

What happens to a sequestered disc?

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.

How common is a sequestered disc?

Although sequestered disc fragments accounts for 28.6% of all disc herniations [3], migration to the posterior epidural space or into the dural sac is rare, with an incidence rate about 0.27–1.04% [4, 5].

What causes disc sequestration?

The main cause of disc sequestration is disc degeneration. Disk degeneration decreases the flexibility of the disks which increases the risk of damage caused by strain or injury.

How long does it take for a sequestered disc to reabsorb?

In Takada et al.’s study [8], all cases of sequestrated discs were completely resolved after 9 months, whereas extruded discs were only completely resolved after 12 months.
