Bone spurs

Osteoarthritis is the most common cause of bone spurs

These are bony growths formed on normal bone, commonly the spine, hands, shoulders, hips, knees and feet. They are usually smooth, but can cause pain if they rub on other bones or soft tissue.

Osteoarthritis is the most common cause of bone spurs. This form of arthritis breaks down cartilage that cushions the ends of your bones, and your body attempts to repair the damage by building extra bone.

Bone spurs can go undetected for years, or you can have them and not require treatment. In severe cases, they can press on nerves and cause a lot of pain, so may need to be surgically removed.

Complications can also result if the spur breaks off and becomes embedded in the lining of your joint.
