Bone spurs are bony projections that develop along the edges of bones. Also called osteophytes, bone spurs often form where bones meet each other — in your joints. Bone spurs can also form on the bones of your spine.
The main cause of bone spurs is the wear-and-tear damage associated with osteoarthritis. Most bone spurs cause no symptoms and may go undetected for years. Bone spurs may not require treatment. Decisions about treatment depend on where spurs are located and how they affect your health.
