Patients with lumbar spinal stenosis are heavier than those with lumbar disc herniation because lumbar spinal stenosis is caused by continuous degeneration of the lumbar spine area over a very long period of time resulting in a significant narrowing of the local nerve travel area, which produces compression and irritation of the nerves and can lead to significant ischemic symptoms of the nerves, numbness and related manifestations such as intermittent claudication. There are many patients with lumbar disc herniation already present, which is a related manifestation caused by the location of the herniated disc irritating the nerve roots, resulting in edema or ischemia of the nerve roots. Surgery for lumbar spinal stenosis requires open surgery, which is relatively invasive. Patients with lumbar spinal stenosis are often combined with lumbar disc herniation, and the spinal canal is surgically opened to decompress the spinal canal. If there is a lot of local hyperplasia and calcified lesions, it is also necessary to remove the herniated disc by biting with a bone crusher in order to avoid continued nerve compression and irritation. Patients with lumbar disc herniation, whose symptoms are relatively mild, can be treated by foraminoscopy, which is less invasive, less expensive, and has a relatively good prognosis. With increasing age, there are many patients with lumbar disc herniation in which the herniated disc gradually dehydrates and atrophies, producing less irritation to the nerves, and the symptoms gradually disappear.
