Not all cases of lumbar disc herniation require surgery, and sometimes can be treated conservatively, as follows: a. In mild lumbar disc herniation, the patient has only intermittent symptoms of lumbar pain and radiating pain in the legs, and does not have severe limitation of lumbar spine activities and muscle atrophy of the lower limbs. Such patients can be treated conservatively, including bed rest, lumbar traction, ultrashort wave therapy and oral celecoxib, which can clearly improve the clinical symptoms and restore the function of the lumbar region. Second, severe lumbar disc herniation can lead to muscle atrophy of the lower limbs and even dysfunction of the second stool. At this time, surgery should be considered to remove the herniated nucleus pulposus tissue, release the nerve compression, restore the nerve conduction as well as the motor function of the lower limbs, which can clearly improve the patient’s normal quality of life. Therefore, the need for surgery for patients with lumbar disc herniation needs to be decided according to the severity of the condition.
