Spinal stenosis (spinal stenosis) is a type of disease in which various causes shorten the diameter of the spinal canal and compress the dural sac, spinal cord or nerve roots, resulting in a series of neurological dysfunctions such as pain, numbness, limb weakness, claudication, and urinary and fecal disorders. Spinal stenosis is divided into cervical spinal stenosis, thoracic spinal stenosis, and lumbar spinal stenosis from the site of stenosis. From the etiology, it is mainly divided into congenital spinal stenosis and acquired spinal stenosis. The spinal stenosis is either congenital or acquired, and the more common is acquired spinal stenosis, which is mainly caused by degeneration of the spine. Ligamentous hypertrophy, osteophytes, and herniated discs occur as people age, and these causes can cause spinal stenosis. Congenital spinal stenosis is relatively uncommon. The main symptom of spinal stenosis is related to compression of the spinal cord or nerves in the spinal canal, and the most typical symptom is intermittent claudication. Intermittent claudication means that after walking one or two hundred meters, you can no longer walk because of pain and must rest before walking again. Treatment of spinal stenosis should be early with medication, such as conservative treatment, rest, and non-steroidal anti-inflammatory pain medication. If conservative treatment is ineffective, surgery may be the only treatment option.
