Some people are born with a small spinal canal. It can also happen with aging. Other things that may cause it are:
- Osteoarthritis and osteophytes (bony spurs) from aging
- Rheumatoid arthritis
- Spinal tumors
- Paget disease of the bone
Spinal stenosis causes pain and other symptoms. Stenosis can occur anywhere along the spinal cord. It is most common in the low back (lumbar) region.
Spinal stenosis may cause:
- Spreading pain in the lower back, buttock, or lower limb
- Problems walking
- Numbness, tingling, or loss of feeling in the feet
- Weak muscles
The doctor will ask about your symptoms and health history. A physical exam will be done.
Images may be taken of your spinal canal. This can be done with:
- MRI scan
- CT scan
The electrical activity of your nerves, nerve roots, and muscle tissue may be measured. This can be done with electromyography.
There is no cure. The goal of treatment is to ease symptoms. Options may be:
- Medicine to ease pain and swelling
- A corset or brace to keep the spine stable
- Exercises to keep the spine stable and promote strength and motion
Some people with severe symptoms may need surgery to take pressure off of the nerves or spinal cord. Options are:
- Decompression laminectomy to remove part of the vertebra, ligaments, and/or bone spurs to make room for the nerves and spinal cord
- Spinal fusion to fuse 2 vertebrae together to support the spine. This is almost always done after decompression laminectomy.
