spinal stenosis
Information, Symptoms, Treatments and Resources
Spinal stenosis is a narrowing of the lumbar (back) or cervical (neck) spinal canal, which causes compression of the nerve roots.
Spinal stenosis mainly affects middle-aged or elderly people. It may be caused by osteoarthritis or Paget's disease or by an injury that causes pressure on the nerve roots or the spinal cord itself.
Neurological examination confirms leg weakness and decreased sensation in the legs.
- EMG may show neurological changes.
- Spinal MRI or spinal CT scan shows spinal stenosis.
- X-ray of the spine shows degenerative changes and narrowed spinal canal.
Generally, conservative management is encouraged. This involves the use of anti-inflammatory medications, other pain relievers, and possibly steroid injections. If the pain is persistent and does not respond to these measures, surgery is considered to relieve the pressure on the nerves.
Surgery is performed on the neck or lower back, depending on the site of the nerve compression.
If the nerve roots can be successfully relieved of pressure, the symptoms will not worsen and may improve.
Injury can occur to the legs or feet due to lack of sensation. Infections may get worse because pain related to them may not be felt. Changes caused by nerve compression may be permanent, even if the pressure is relieved.
Call your health care provider if you have symptoms of spinal stenosis.
