Understanding Spinal Stenosis
You may hear the term spinal stenosis used in relation to other conditions that affect the spine, but what does stenosis mean?
"Stenosis" is derived from the ancient Greek word for "narrowing." Therefore, spinal stenosis refers to a narrowing of the spinal canal. This space is typically wide enough to comfortably house the spinal cord as it runs from the base of the brain to the lower mid-back. However, if an anatomical abnormality develops in the spine, it is possible that the abnormality could intrude upon the spinal canal's space and compress the spinal cord or its nerve roots.
Spinal Stenosis Causes
There are a number of conditions that can lead to the narrowing of the spinal canal -- and the potential compression of the spinal cord or nerve roots -- including:
- Bulging discs
- Herniated discs
- Inflamed ligaments or tendons
- Bone spurs
It is also possible that an injury, disease, or infection within the spine could cause spinal canal blockage. Additionally, some individuals are born with a birth defect that leaves them with an abnormally narrow spinal canal.
Nerve Compression
If the spinal cord is compressed, or pinched, due to spinal stenosis, a number of symptoms may develop. Typically, a pinched spinal cord presents with localized pain near the area of compression. Depending on the location of the spinal canal blockage, pain, numbness, tingling, and weakness may also radiate down the neck, shoulders, arms, and hands, or through the lower back, buttocks, hips, legs, and feet. Symptoms may worsen when standing or walking for long periods of time, as the spinal canal naturally narrows when extended. Flexion of the spine widens the spinal canal, so many patients may find relief when leaning forward or sitting down.
If You Are In Pain
If you believe your back or neck pain is a result of spinal stenosis, call your doctor. After diagnosing the condition that has caused narrowing within the spinal canal, he or she will likely recommend that you begin a course of conservative (non-surgical) treatments, such as non-steroidal anti-inflammatory drugs (NSAIDs), physical therapy, and hot/cold therapy. |
