What is spinal stenosis?
Spinal stenosis refers to the narrowing of the spinal canal. This is most often a condition that develops as a person ages, although in rare circumstances it is present at birth. This condition can also be caused by arthritic changes, injury or surgery. Diagnosis of spinal stenosis is confirmed through testing such as MRI, CT scan or Myelogram.
What are the effects of spinal stenosis?
When the spinal canal becomes narrowed, the nerves which pass through can be compressed. This may cause them to become inflamed which can cause pain in the low back, or one or both legs. Symptoms may also include pain in the legs which occurs after walking and is relieved by rest and/or a feeling of coldness, weakness, numbness or cramping in the legs. The onset of these symptoms may be slow or sudden.
How is spinal stenosis treated?
Treatment of this condition depends on the number of vertebrae involved, the amount of pain and the condition of the patient’s general health. Non-surgical treatments include use of the non-steroidal anti-inflammatory medication, physical therapy, spine education programs, rest and the application of ice. Epidural steroid injections into the epidural space of the spine may reduce inflammation and pain. Surgical treatment involves removing the bone compressing the spinal cord or nerves and allowing them to move freely. If this bone removal makes the spine less stable, a spinal fusion may be done to immobilize the area.
