<p><strong>What Is Spinal Stenosis?</strong></p>
<p>Spinal stenosis is a narrowing of the spinal canal, the cavity within the vertebral column through which the spinal cord and nerves pass. Nerves leaving the spinal cord are called nerve roots; they pass through the vertebral column via small canals. Arthritic changes that cause overgrowth of vertebral bones may compress the spinal cord or the nerve roots, impairing sensation and muscle strength in the affected portion of the body. Most common among people in their 50s and 60s, spinal stenosis affects the lumbar (lower back) portion of the spine more than the cervical (neck) region. Symptoms include pain, numbness, and weakness in the neck, arms, lower back, and legs. As a result of leg weakness, people are prone to falls. Because the nerves controlling the bladder emerge from the lower spine, spinal stenosis may also cause urinary incontinence.</p>
