Bone spurs are usually caused by local inflammation, such as from degenerative arthritis (osteoarthritis) or tendinitis. This inflammation stimulates the cells that form bone to deposit bone in this area, eventually leading to a bony prominence or spur. For example, inflammation of the ligament that surrounds a degenerating disc between the vertebrae (the bony building blocks of the spine) is a very common cause of bone spurs of the spine. Inflammation of the Achilles tendon can lead to the formation of a bone spur at the back of the heel bone (calcaneus bone). Inflammation of the tissue on the bottom of the foot, plantar fasciitis, can lead to a bone spur at the underside of the heel bone. These bone spurs are sometimes referred to as heel spurs. A bone spur is medically referred to as an osteophyte.
Rarely, bone spurs may occur as a result of congenital conditions. An
osteochondroma is one type of these congenital spurs.

A bone spur is a small piece of bone that projects from the normal bone around joints. Spurs usually are caused by inflammation that stimulates formation of new bone. Examples of causes of local inflammation at the edge of joints that cause spurs are inflammation of the tendons and ligaments that attach to the bone. For example, inflammation of the ligament that surrounds a degenerating disc between the vertebrae (bony building blocks of the spine) is a very common cause of bone spurs of the spine.
