The herniation of the lumbar disc occurs due to degeneration of the disc, causing the nucleus pulposus to protrude backwards from the ruptured annulus fibrosus, compressing the spinal cord and nerve roots, thus leading to a series of symptoms. There will be pain in the lumbar region, and restricted flexion and extension movements of the waist. Symptoms may include numbness in the lateral calf and dorsum of the foot, weakness in walking, decreased muscle strength in the dorsiflexion of the big toe and ankle. In severe cases, there may be loss of control over urination and defecation. Therefore, when a disc herniation occurs, it is important to diagnose and treat it early to avoid worsening of symptoms.
