Spondylosis is a type of arthritis spurred by wear and tear to the spine. It happens when discs and joints degenerate, when bone spurs grow on the vertebrae, or both. These changes can impair the spine's movement and affect the nerves and other functions.

What is the main cause of spondylosis?

The main cause is aging, but the way aging affects your spine can lead to other changes and problems. Spondylosis is a cascade: One anatomical change occurs, which leads to more degeneration and changes in your spine's structures. These changes combine to cause spondylosis and its symptoms.

Is spondylosis serious?

Spondylosis is common, but it is usually not serious. Many who have it experience no pain, though it can be painful for some. Most patients with spinal osteoarthritis will not need surgery.
