Illustration of Spinal Stenosis | Central Stenosis of the Spine | Colorado Spine Doctor
This illustration demonstrates the change in the diameter in the canal in a patient with spinal stenosis. The picture on the right shows the canal wide open with flexion (bending forward). The picture on the left shows significant compression of the nerve sac in the canal (arrow) with backwards bending. Standing and walking require backwards bending, so the symptoms of central stenosis occur with walking and standing.
