Causes

By Mayo Clinic staff

Wear-and-tear arthritis (osteoarthritis) is the most common cause of bone spurs. As osteoarthritis breaks down the cartilage cushioning the ends of your bones, your body attempts to repair the loss by creating bone spurs near the damaged area. The extra bone may help increase the amount of surface area for load bearing.
