A bone spur (osteophyte) is a bony growth formed on normal bone. Most people think of something sharp when they think of a spur, but a bone spur is just extra bone. It's usually smooth, but it can cause wear and tear or pain if it presses or rubs on other bones or soft tissues such as ligaments, tendons, or nerves in the body.
