Lumbar disc herniation is a series of clinical symptoms and signs caused by degeneration of the lumbar disc, rupture of the annulus fibrosus and protrusion of the nucleus pulposus that irritates or compresses the nerve root and cauda equina nerve, commonly known as “lumbar protrusion”. It often causes a lot of pain in life and work, and even disability and loss of working ability. Lumbar disc herniation is the main cause of low back pain and is one of the most common orthopedic clinical disorders, accounting for 10%-15% of patients with low back pain in orthopedic outpatient clinics and 25%-40% of hospitalization cases for low back pain. The most common symptom in patients with lumbar disc herniation is pain, which can be manifested as low back pain and sciatica, and typical sciatica manifests as radiating pain from the hip, the back of the thigh, the lateral calf to the heel or the back of the foot. According to clinical statistics, about 95% of patients with lumbar synostosis have varying degrees of low back pain and 80% of patients have lower limb pain. In particular, lumbar pain is not only the most common symptom of lumbar disc herniation, but also one of the earliest symptoms. The pain occurs mainly due to the stimulation and compression of adjacent tissues (mainly sinus nerve and spinal nerve root) by the herniated and degenerated nucleus pulposus, as well as the overflow of biological substances such as glycoproteins in the nucleus pulposus, the release of histamine and other local chemical inflammation caused by chemical and mechanical radiculitis, resulting in mild or severe chronic back and leg pain. Moreover, degeneration of the lumbar spine also often occurs simultaneously in other tissues of the lumbar region, such as small intervertebral joints, ligaments, and lumbar muscles, causing local chronic inflammation of these tissues and causing pain. The two factors interact with each other and aggravate each other, causing progressive development of lumbar and leg pain.
