Cervical spondylosis is a general term for age-related wear of the intervertebral discs in the neck. When the intervertebral discs become dehydrated and shrink, signs of osteoarthritis develop, including bony protrusions along the edges of the bone (bone spurs).Cervical spondylosis is very common and worsens with age. More than 85% of people over the age of 60 have cervical spondylosis.
Most people have no symptoms of these problems. When symptoms appear, nonsurgical treatments are often effective.
In most people, cervical spondylosis does not cause symptoms. When symptoms appear, they usually include pain and stiffness in the neck.Sometimes cervical spondylosis causes a narrowing of the space required by the spinal cord and the nerve roots that run through the spine to the rest of the body. If the spinal cord or nerve roots are pinched, the following may occur:
Tingling, numbness, and weakness in the arms, hands, legs, or feet
Lack of coordination and difficulty walking.
Loss of bladder or bowel control.
As you age, the bones and cartilage that make up your spine and neck gradually grow downward. These changes can include:
1- Dehydrated slices:-
The discs act as cushions between the vertebrae in your spine. By age 40, most people’s spinal discs begin to dry out and shrink, allowing more bone contact between the vertebrae.
2- Disc prolapse:-
Age also affects the appearance of your spinal discs. Cracks often appear, leading to bulging intervertebral (intervertebral) discs that can sometimes press on the spinal cord and nerve roots.
3 -Bone spurs:-
Disc degeneration often leads the spine to produce additional amounts of bone in a misguided attempt to strengthen the spine. These bone spurs can sometimes pinch the spinal cord and nerve roots.
4- Rigid ligaments:-
Ligaments are cords of tissue that connect bones to bones. The ligaments in your spine can stiffen with age, making your neck less flexible.
