परिभाषा
Spinal 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.
का कारण बनता है
Some people are born with narrowed canals. Most often stenosis is a result of aging. Conditions that can cause spinal stenosis include:
- Osteoarthritis and osteophytes (bony spurs) associated with aging
- रूमेटाइड गठिया
- स्पाइनल ट्यूमर
- सदमा
- Paget’s disease of the bone
- पिछली सर्जरी
जोखिम कारक
Factors that increase your chance of spinal stenosis include:
- Being born with a narrow spinal canal
- आयु: 50 या उससे अधिक
- Previous injury or surgery of the spine
लक्षण
लक्षणों में शामिल हैं:
- Numbness, weakness, cramping, or pain in the legs and thighs
- Radiating pain down the leg
- Abnormal bowel and/or bladder function
- Decreased sensation in the feet causing difficulty placing the feet when walking
- यौन क्रिया का नुकसान
- Partial or complete paralysis of legs
निदान
आपका डॉक्टर आपके लक्षणों और चिकित्सा इतिहास के बारे में पूछेगा। एक शारीरिक परीक्षा ली जाएगी।
परीक्षण में शामिल हो सकते हैं:
- X-ray—a test that uses radiation to take pictures of structures inside the body; in this case, to check for abnormalities in the bones of the back including osteoarthritis, bone spurs, and obvious narrowing of the spinal canal
- CT scan—a type of x-ray that uses a computer to make pictures of the bones of the back, which helps to evaluate the spinal canal
- MRI scan—a test that uses magnetic waves to make pictures of soft tissue, such as the spinal cord and the spinal nerves inside the back
उपचार
उपचार में शामिल हैं:
दवा
- Nonsteroidal anti-inflammatory drugs (NSAIDs)—to relieve pain and inflammation
- Analgesics—to relieve pain
- Corticosteroid injections—to reduce pain and inflammation
शारीरिक चिकित्सा
Special 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
Wearing a corset or lumbar brace can help stabilize the spine. This may relieve pain.
सर्जरी
Surgery is reserved for severe cases.
- Decompression laminectomy —This is the removal of bony spurs or increased bone mass in the spinal canal. This can free up space for the nerves and the spinal cord.
- Spinal fusion —This is when two vertebrae (back bones) are fused together. This will provide stronger support for the spine. This is almost always done after decompression laminectomy.
रोकथाम
There are no guidelines for preventing spinal stenosis.
