A heel spur is a calcium deposit on the underside of the heel bone. On an X-ray, a heel spur protrusion can extend forward by as much as a half-inch. Without visible X-ray evidence, the condition is sometimes known as “heel spur syndrome.”
Although heel spurs are often painless, they can cause heel pain. They are frequently associated with plantar fascitis, a painful inflammation of the fibrous band of connective tissue (plantar fascia) that runs along the bottom of the foot and connects the heel bone to the ball of the foot.
Treatments for heel spurs and associated conditions include excercise, custom-made orthotics, anti-inflammatory medications, and cortisone injections. If conservative treatments fail, surgery may be necessary.
