Patients with lumbar disc herniation and spinal stenosis can usually be cured after surgery. 1. Patients with lumbar disc herniation and spinal stenosis can consider surgery if their symptoms are severe and conservative treatment is not effective. Surgery can relieve the pressure on the nerve roots and spinal cord, thus causing the symptoms to disappear. 2. There are many types of surgery, such as disc removal and radiofrequency ablation for patients with lumbar disc herniation, and spinal decompression for patients with spinal stenosis to relieve the compression of the spinal cord, nerve roots and other neural tissues, and eliminate the symptoms. 3. Surgery can remove the herniated disc lesions and decompress the spinal canal and nerve root canal, completely removing the compression factors of the spinal cord and nerves, so that the nerves can resume normal blood supply. 4. After the surgery, the spinal cord nerves can gradually complete the self-repair of the damage, and gradually restore the normal nerve conduction function, and the pain and numbness symptoms disappear. To summarize, patients who meet the indications for surgery and choose surgical treatment can get satisfactory results.
