Spinal stenosis
Spinal Stenosis
Spinal stenosis (/ˈspaɪnəl stɪˈnoʊsɪs/) is a medical condition where the spaces within your spine narrow, which can put pressure on the nerves that travel through the spine.
Etymology
The term "spinal stenosis" is derived from the Greek words "spinos" meaning spine, and "stenos" meaning narrow.
Definition
Spinal stenosis occurs when the space around the spinal cord, also known as the spinal canal, becomes narrowed. This can lead to a pinching of the spinal cord and nerve roots, causing pain, tingling, or numbness in your arms or legs. It is most commonly caused by wear-and-tear changes in the spine related to osteoarthritis.
Symptoms
Symptoms of spinal stenosis may include:
- Pain or cramping in the legs when standing for long periods of time or when walking
- Numbness, tingling, or hot and cold sensations in the legs
- Weakness or a heavy feeling in the legs
- A loss of balance
- Severe cases can affect bowel and bladder function
Causes
Spinal stenosis is typically caused by age-related changes in the spine. Other causes can include:
- Osteoarthritis and the resulting bone spurs
- Rheumatoid arthritis
- Spinal injuries
- Congenital spinal deformity
- Tumors of the spine
Treatment
Treatment for spinal stenosis depends on the location and severity of the condition. It may include:
- Medications such as pain relievers, antidepressants for chronic pain, or anti-seizure drugs to reduce nerve pain
- Physical therapy to build strength and endurance, maintain the flexibility and stability of the spine, and improve balance
- Steroid injections to reduce inflammation
- Surgery in severe cases, such as laminectomy, laminotomy, or spinal fusion
