Spinal stenosis is a medical condition characterized by the narrowing of spaces within the spine, which can lead to pressure on the spinal cord or nerve roots. This condition is most prevalent in individuals over the age of 50 and can result in symptoms like pain, numbness, or weakness, particularly in the lower back and legs.
There are two primary types of spinal stenosis: central stenosis and foraminal stenosis. Central stenosis refers to the narrowing of the spinal canal itself, the main channel through which the spinal cord passes. Foraminal stenosis, on the other hand, involves the tightening of the openings where nerve roots exit the spinal column. This narrowing can be caused by various factors, including age-related spinal degeneration, bone spurs, and thickened ligaments.
One common form of spinal stenosis is lumbar spinal stenosis, which occurs in the lower back. Another is cervical stenosis, where the spinal canal in the neck region becomes too small for the spinal cord and nerve roots, potentially leading to myelopathy (damage to the spinal cord) or radiculopathy (pinched nerves).
Treatment for spinal stenosis varies depending on the severity and location of the condition. Options range from conservative, non-surgical methods to surgical decompression. Advanced minimally invasive techniques are also available, offering quicker recovery times. Washington University spinal neurosurgeons, for instance, provide a full range of treatments for this condition.
Symptoms of spinal stenosis can include pain, fatigue, and a noticeable discomfort in the lower back, extremities, or buttocks. The pain may be intermittent and can range from vague to severe.
