Spinal Stenosis

Introduction

Spinal stenosis is a narrowing of the spinal canal in the space where the canal houses the nerves. This narrowing results in a pinching of the nerves and can occur in the neck (cervical spine) or lower back (lumbar spine).

This condition is most commonly caused by degeneration of the spine due to aging or a traumatic injury to the spine. Arthritis in the neck and/or back can also cause the intervertebral discs to bulge, cause bone spurs and cause ligaments in the back to thicken; all of which contribute to spinal stenosis.

Symptoms of spinal stenosis include back pain that spreads to the legs, numbness, weakness and/or pain in the arms or legs, difficulty walking and pain or numbness in the buttocks, thighs and or calves that is worsened by walking or exercise.

Spinal Stenosis is diagnosed through various imaging techniques including X-rays and MRI.
