Lumbar disc herniation is a very common clinical disease, and it is helpful to understand and recognize this disease for treatment and rehabilitation. Many people think that the disease will lead to paralysis, loss of labor and life ability, but in fact, except for very few cases of paralysis or unilateral limb incomplete paralysis, most cases appear to be back pain, leg pain, numbness, and difficulty walking. The cause is the degeneration and injury of the lumbar spine, resulting in the imbalance of the internal and external mechanical balance of the spinal canal, coupled with external forces, causing partial or complete rupture of the lumbar intervertebral disc fibrous ring, the nucleus pulposus protrudes outward, compressing the nerve roots or spinal cord, causing a series of neurological symptoms (such as low back pain, sensory impairment, weakness, abnormalities in the second stool, etc.). Long-term bending (such as professional drivers), excessive weight-bearing, and sprains cause intervertebral pressure to increase, leading to protrusion. Clinical manifestations of recurrent low back pain and radiating pain to one side of the lower limbs, difficulty in turning over, coughing, sneezing, pain aggravated by increased abdominal pressure when straining to defecate, lower limb pain mostly distributed to the sciatic nerve, pressure pain and radiating pain in the lumbar region, CY, MR can clearly diagnose. Treatment is bed rest for 1-2 weeks (slightly hard mattress is better) to reduce intervertebral pressure, traction, oral painkillers, local closure, blood circulation and pain relief are feasible, and conservative treatment for 1-3 months without improvement is feasible for surgery.
