Spinal stenosis can be diagnosed through X-rays, magnetic resonance imaging (MRI), computed tomography (CT) scans and blood tests. Common treatments include physical therapy, medication or, in severe cases, surgery to relieve pressure on the spinal cord and/or nerves.
Surgery can be performed by removing, trimming or adjusting diseased areas of the spine that are causing pressure or loss of alignment. The most common surgery for spinal stenosis is a laminectomy, which involves removing the back part of affected vertebra to open up space for the nerves. In some cases, surgery may also involve the fusion of vertebrae in order to strengthen portions of the spine.
