Lumbar dural sac compression can be treated by the following methods: First, conservative treatment: If the lumbar dural sac compression is mild, the patient’s clinical symptoms are not obvious, and only proper rest and strengthening of the lumbar back muscle strength training are needed. Second, surgical treatment: if the lumbar dural sac compression is more serious, the patient has obvious lumbar pain, leg pain and muscle atrophy of the lower limbs, surgery needs to be considered to surgically remove the protruding nucleus pulposus tissue, expand the narrow spinal canal and release the dural sac compression, which can completely relieve the clinical symptoms. After surgery, the strength training of the lumbar back muscles needs to be strengthened to consolidate the treatment effect of surgery and prevent the recurrence of clinical symptoms. If a patient is diagnosed with lumbar dural sac compression, the appropriate treatment should be selected according to the different degrees of compression to bring about relief of clinical symptoms as soon as possible.
