Spinal stenosis: New study purports to show surgery better than medical management
Metadata[+] Show full item record
Lumbar spinal stenosis is a narrowing of the spinal canal, often caused by an overgrowth of vertebral bone due to degenerative disease or by disc herniation. The condition is most common among patients older than 65 years. Symptoms include lower back or leg pain, numbness, or weakness that worsens with walking and improves with sitting or bending forward. The physical examination is frequently normal.
