Lumbar Spinal Stenosis

Lumbar spinal stenosis is a condition whereby either the spinal canal (central stenosis) or one or more of the vertebral foramina (foraminal stenosis) becomes narrowed. If the narrowing is substantial, it causes compression of the spinal cord or spinal nerves, which causes the painful symptoms of lumbar spinal stenosis, including low back pain, buttock pain, and leg pain and numbness that is made worse with walking and relieved by resting. Lumbar spinal stenosis is typically caused by degenerative arthritis.  As with other joints in the body, arthritis commonly occurs in the spine as part of the normal aging process and as a result of osteoarthritis. This can lead to loss of the cartilage between the bones at the joints symptoms include tumor of the local structures or metastatic tumors (tumors that originated in another part of the body and spread to this location), infection, various metabolic bone disorders that cause bone growth, such as Paget's disease of bone
