The herniated nucleus pulposus does not atrophy, it persists and is an irreversible lesion. Once herniated, the herniated nucleus pulposus may persist and worsen due to subsequent compression and local overstrain, and will not retract or atrophy because the nucleus pulposus itself is a cartilage-related structure that is not regenerable and cannot be absorbed by the body. After the nucleus pulposus is herniated, it will exist in the spinal canal for a long time, compress and irritate the nerve roots, and in serious cases, it will even prolapse and become free in the spinal canal, causing compression and irritation to the surrounding nerves from time to time. Therefore, patients suffering from lumbar disc herniation should not expect the herniated nucleus pulposus to atrophy in order to achieve disease relief. The lumbar disc herniation should be actively treated accordingly, and in some serious cases, surgery is required to remove the herniated nucleus pulposus completely.
