A heel spur occurs when calcium deposits build up on the underside of the heel bone. The abnormal calcium deposits form when the plantar fascia pulls away from the heel. This stretching of the plantar fascia is common among people who have flat feet, but people with unusually high arches can also develop this problem. Heel spurs are especially common among athletes who do a lot of running and jumping. Also, women who wear high heels have a significantly higher incidence of heel spurs. Still, it can happen to anyone.
The calcaneal spur is seen most often in persons over the age of 40. The condition can also be associated with osteoarthritis, rheumatoid arthritis, poor circulation of the blood and other degenerative diseases. Men and women are equally likely to have them.
An individual with the lower legs turning inward, a condition called genu valgus or "knock knees," can have a tendency toward excessive pronation. This can lead to a fallen arch and problems with the plantar fascia and heel spurs. Women tend to suffer from this condition more than men. Heel spurs can also result from an abnormally high arch. Other factors leading to heel spurs include a sudden increase in daily activities, an increase in weight, or a thinner cushion on the bottom of the heel due to old age. A significant increase in training intensity or duration may cause inflammation of the plantar fascia. High-heeled shoes, improperly fitted shoes, and shoes that are too flexible in the middle of the arch or bend before the toe joints will cause problems with the plantar fascia and possibly lead to heel spurs.
A thorough history and physical exam is always necessary for the proper diagnosis of heel spurs and other foot conditions. X rays of the heel area are helpful, as excess bone production will be visible.
Non Surgical Treatment
There are many temporary solutions to resolve the pain associated with irritation to the plantar ligaments. Common recommendations are ice and anti-inflammatory medications or even cortisone injections, however none of these solve the fundamental problem. To permanently resolve heel spurs you need to support and restrict the movement of the plantar ligaments. Flexible shoes will aggravate and often contribute to heel spurs. We recommend a RIGID orthotic that extends from the metatarsal heads to the heel to resolve heel spurs.
Sometimes bone spurs can be surgically removed or an operation to loosen the fascia, called a plantar fascia release can be performed. This surgery is about 80 percent effective in the small group of individuals who do not have relief with conservative treatment, but symptoms may return if preventative measures (wearing proper footwear, shoe inserts, stretching, etc) are not maintained.
