The symptoms of spinal stenosis can also be caused by many other conditions, which makes spinal stenosis difficult to diagnose. There is usually no history of back problems or any recent injury. Often, unusual leg symptoms are a clue to the presence of spinal stenosis. If simple treatments, such as postural changes or non-steroidal anti-inflammatory drugs, do not relieve the problem, your orthopaedic surgeon may request special imaging studies to determine the cause of the problem. An MRI (magnetic resonance image) or CAT (computed tomography) scan may be requested. A myelogram (an X-ray taken after a special fluid is injected into the spine) may be arranged. These and other imaging studies provide details about the bones and tissues and assist the orthopaedic evaluation.
