Spine Treatment In India
Spinal stenosis is a narrowing of the spaces within your spine, which can put pressure on the nerves that travel through the spine. Spinal stenosis occurs most often in the lower back and the neck. Some people with spinal stenosis may not have symptoms. Others may experience pain, tingling, numbness and muscle weakness. Symptoms can worsen over time. Spinal stenosis is most commonly caused by wear-and-tear changes in the spine related to osteoarthritis. In severe cases of spinal stenosis, doctors may recommend surgery to create additional space for the spinal cord or nerves.The backbone (spine) runs from your neck to your lower back. The bones of your spine form a spinal canal, which protects your spinal cord (nerves). Some people are born with a small spinal canal. But most spinal stenosis occurs when something happens to narrow the open space within the spine. Causes of spinal stenosis may include:
Types of spinal stenosisThe types of spinal stenosis are classified according to where on the spine the condition occurs. It's possible to have more than one type. The two main types of spinal stenosis are:
- Cervical stenosis. In this condition, the narrowing occurs in the part of the spine in your neck.
- Lumbar stenosis. In this condition, the narrowing occurs in the part of the spine in your lower back. It's the most common form of spinal stenosis.
SymptomsMany people have evidence of spinal stenosis on an MRI or CT scan but may not have symptoms. When they do occur, they often start gradually and worsen over time. Symptoms vary depending on the location of the stenosis and which nerves are affected.
In the neck (cervical spine)
- Numbness or tingling in a hand, arm, foot or leg
- Weakness in a hand, arm, foot or leg
- Problems with walking and balance
- Neck pain
- In severe cases, bowel or bladder dysfunction (urinary urgency and incontinence)
In the lower back (lumbar spine)
- Numbness or tingling in a foot or leg
- Weakness in a foot or leg
- Pain or cramping in one or both legs when you stand for long periods of time or when you walk, which usually eases when you bend forward or sit
- Back pain
When to see a doctorSee your doctor if you have any of the symptoms listed.
Herniated disk and bone spurs on spine
- Overgrowth of bone. Wear and tear damage from osteoarthritis on your spinal bones can prompt the formation of bone spurs, which can grow into the spinal canal. Paget's disease, a bone disease that usually affects adults, also can cause bone overgrowth in the spine.
- Herniated disks. The soft cushions that act as shock absorbers between your vertebrae tend to dry out with age. Cracks in a disk's exterior may allow some of the soft inner material to escape and press on the spinal cord or nerves.
- Thickened ligaments. The tough cords that help hold the bones of your spine together can become stiff and thickened over time. These thickened ligaments can bulge into the spinal canal.
- Tumors. Abnormal growths can form inside the spinal cord, within the membranes that cover the spinal cord or in the space between the spinal cord and vertebrae. These are uncommon and identifiable on spine imaging with an MRI or CT.
- Spinal injuries. Car accidents and other trauma can cause dislocations or fractures of one or more vertebrae. Displaced bone from a spinal fracture may damage the contents of the spinal canal. Swelling of nearby tissue immediately after back surgery also can put pressure on the spinal cord or nerves.
Risk factorsMost people with spinal stenosis are over the age of 50. Though degenerative changes can cause spinal stenosis in younger people, other causes need to be considered. These include trauma, congenital spinal deformity such as scoliosis, and a genetic disease affecting bone and muscle development throughout the body. Spinal imaging can differentiate these causes.
ComplicationsRarely, untreated severe spinal stenosis may progress and cause permanent:
- Balance problems
