Lumbar disc herniation is one of the more common disorders, mainly because the lumbar intervertebral disc parts (nucleus pulposus, fibrous ring and cartilage plate), especially the nucleus pulposus, have different degrees of degenerative changes, under the action of external factors, the fibrous ring of the disc ruptures, and the nucleus pulposus tissue protrudes (or prolapses) from the rupture in the posterior or vertebral canal, resulting in the adjacent spinal nerve roots suffer from irritation or compression, thus producing lumbar pain This results in a series of clinical symptoms, such as numbness and pain in one or both lower extremities. The incidence of lumbar disc herniation is highest in lumbar 4-5 and lumbar 5-sacral 1, accounting for about 95%.
