What's a spur?

A bony growth: A bone spur forms as the body tries to repair itself by building extra bone. It generally forms in response to pressure, rubbing, or stress that continues over a long period of time.

Extra bone growth: 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. Common places for bone spurs include the spine, shoulders, hands, hip.

Spur : Most spurs are completely asymptomatic. They don't need any specific treatment. Very few need surgery.
