Nerves that branch out to the body from the spinal cord must pass through openings in the sides of each vertebra. When one of the openings, called a foramen, in the vertebrae narrows, a condition called spinal stenosis results. The opening can grow too small for the nerve to comfortably pass through and the nerve root can become pinched or irritated.

Spinal stenosis has a reputation of being difficult to diagnose because the symptoms are similar to those of many other conditions. To get an accurate diagnosis and understanding of the extent of the condition, your Sutter physician may conduct advanced imaging studies that may include spinal X-ray, computed tomography (CT) scan of the spine, magnetic resonance imaging (MRI) of the spine, myelogram, electromyogram (EMG) and nerve conduction studies.

Depending on the cause and severity of the condition, Sutter offers conservative, noninvasive, minimally invasive and complex surgical treatment options.

Spinal stenosis is a condition that can result from various bone, joint and tissue diseases. For a complete description, see our Healthwise health information sections on spinal stenosis and cervical spinal stenosis. The Other Places to Get Help section of the Healthwise article offers additional resources for information and support.
