Overview: Lumbar disc herniation is a syndrome manifested by degeneration of the intervertebral disc, rupture of the annulus fibrosus, and protrusion of the nucleus pulposus to irritate or compress the nerve roots and cauda equina, and is one of the most common causes of back and leg pain. The incidence is highest in the L4-5 and L5-S1 gaps. It belongs to the category of low back pain and paralysis in Chinese medicine. Diagnosis: Refer to the diagnostic criteria for lumbar intervertebral herniation in the “Diagnostic and Therapeutic Criteria for Chinese Medicine” of the State Administration of Traditional Chinese Medicine in 1994 (1) history of lumbar trauma, chronic strain or cold and dampness, and most patients have a history of chronic lumbar pain before the onset of the disease; (2) often occurs in young adults; (3) lumbar pain radiates to the buttocks and lower limbs, and the pain increases when abdominal pressure increases (e.g. coughing, sneezing); (4) scoliosis, lumbar physiology (4) scoliosis, loss of lumbar physiology, paravertebral pressure at the lesion site, and radiation to the lower extremities, and limitation of lumbar movement; (5) sensory hypersensitivity or dullness in the affected innervation areas of the lower extremities, and muscle atrophy may occur in long-standing cases. (6) X-ray examination: scoliosis, loss of lumbar physiological anterior convexity, possible narrowing of the diseased intervertebral discs, osteophytes on the adjacent edges, CT examination may show the site and degree of disc protrusion or MRI to confirm the diagnosis. Exclusion criteria: (1) combined with lumbar spine tumor, tuberculosis, fracture; (2) other causes of sciatica; (3) herniated nucleus pulposus severely compressing the cauda equina; (4) more than two discectomies or collagen chemolysis; (5) pregnancy and severe cardiac, pulmonary and renal insufficiency. Modern medicine must consider and analyze the symptoms, signs and imaging data together to ensure that all three are consistent. 1, side consistent, most of the lumbar spine in the image of the side of the protrusion and symptoms and signs are consistent, such as CT shows that the disc to the left, the patient feel left leg pain, physical examination: left straight leg elevation test and strengthening positive. 2, the level is consistent: CT shows the level of disc protrusion (gap), the involved N and the lesion N reflected by the chief complaint area and physical signs are consistent. If CT shows L4-5N protruding into the lateral saphenous fossa and L5 spinal nerve root flooding, then the complaint is painful and numb should be lateral to the calf, dorsal to the foot to the bunion, and on examination this area has hypoesthesia, weak thumb dorsal extensor muscles, and normal Achilles tendon reflex. The same interstitial protrusion, the exact location of the protrusion is different, the involvement of N roots are different (L4-5 protrusion pressure L5N root), the central type of protrusion pressure next N root or the entire cauda equina, intervertebral foramen or extradural foramen pressure intersequential N root. 3, the degree of consistency: generally the larger the image shows the protrusion, the heavier the clinical manifestations signs, but not absolutely, but also by the relationship between the location of the protruding disc and the compressed N root
