Spinal Stenosis
by
Editorial Staff and Contributors DefinitionSpinal stenosis is a narrowing of the spinal canal. The spinal canal is located in the backbone. It is a small space that holds the nerve roots and spinal cord. If this space becomes smaller, it can squeeze the nerves and the spinal cord. This causes pain and other symptoms. Stenosis can occur anywhere along the spinal cord. It is most common in the low back (lumbar) region.
Causes TOPSome people are born with narrowed canals. Most often stenosis is a result of aging. Conditions that can cause spinal stenosis include:
Risk Factors TOPSpinal stenosis is more common in people aged 50 years and older. Other factors that may increase the chance of spinal stenosis include:
Symptoms TOPSpinal stenosis may cause:
Diagnosis TOPYou will be asked about your symptoms and medical history. A physical exam will be done. Imaging tests that evaluate your spine and surrounding structures may include: Treatment TOPTreatments include: MedicationMedications that relieve pain and inflammation include:
Physical TherapySpecial exercises can help stabilize the spinal cord. Exercise can increase muscle endurance and mobility of the spine. This can relieve some pain. Sometimes exercises are ineffective against spinal stenosis. Support Devices TOPWearing a corset or lumbar brace can help stabilize the spine. This may relieve pain. Surgery TOPSurgery is reserved for severe cases.
Prevention TOPThere are no guidelines for preventing spinal stenosis.
