When a patient has a lumbar disc protruding backward and compressing the dural sac, it means that the patient’s lumbar spine fibular ring is damaged by external force and the protection of the nucleus pulposus is weakened, so that the nucleus pulposus will easily protrude backward and compress the dural sac, and the patient will have symptoms of nerve compression, and the patient may have lumbar tingling pain, bending difficulties, decreased skin sensation and muscle strength of the lower extremities, difficulty walking, and abnormal bowel movements. abnormalities, or pathological reflexes. After the above situation, the patient should lie flat on a hard bed to reduce the external stimulation of the lumbar region, and at the same time, traction should be given by using a pelvic belt, acupuncture, moxibustion, and electrocautery in the lumbar spine, and mannitol solution can also be injected in a static manner to reduce the pressure in the lumbar spinal canal, which can relieve the clinical symptoms of the patient.
