A heel spur is a pointed bony outgrowth of the bone of the heel (the calcaneus bone). Heel spurs under the sole of the foot (plantar area) are associated with plantar fasciitis. Heel spurs and plantar fasciitis can occur alone or be related to underlying diseases. Heel spurs and plantar fasciitis are treated by measures that decrease the associated inflammation and avoid reinjury.
An individual with the lower legs angulating inward, a condition called genu valgum or “knock knees,” can have a tendency toward excessive pronation. As a result, this too can lead to a fallen arch resulting in plantar fascitis and heel spurs. Women tend to have more genu valgum than men do. 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 change of shoes. Dramatic increase in training intensity or duration may cause plantar fascitis. Shoes that are too flexible in the middle of the arch or shoes that bend before the toe joints will cause an increase in tension in the plantar fascia and possibly lead to heel spurs.

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 Heel Spur diagnosis is made when an X-ray shows a hook of bone protruding from the bottom of the foot at the point where the plantar fascia is attached to the heel bone. The plantar fascia is the thick, connective tissue that runs from the calcaneus (heel bone) to the ball of the foot. This strong and tight tissue helps maintain the arch of the foot. It is also one of the major transmitters of weight across the foot as you walk or run. In other words, tremendous stress is placed on the plantar fascia.
Non Surgical Treatment
In extreme cases, a doctor may recommend surgery for the removal of heel spurs. Fortunately, this is the exception rather than the rule. Most cases can be resolved with a combination of icing, rest, foot stretches and supporting the foot with an orthodic shoe insert specifically designed for this condition. We recommend that you continue on to our article on Heel Spur Treatment to discover the best, speediest and most affordable methods of resolving this ailment without invasive medical procedures.
Surgery to correct for heel spur syndrome is a common procedure which releases plantar fascia partially from its attachment to the calcaneous (heel bone). This part of the surgery is called a plantar fasciotomy due to the fact the fascia is cut. This is most often done through an open procedure as any heel spur or bursa can be removed at the same time. If the spur is not removed during the surgery, it will probably be just as successful, as the large spur is not the true problem. Some physicians use an endoscopic approach (EPF) where a small camera aids the physician during surgery with typically smaller incisions on each side of your foot.
In 2002, researchers attempted to compare the effects of various running techniques on pronation and resulting injuries like stress fractures and heel spurs. They suggested that it is possible to teach runners to stride in such a way as to minimize impact forces. One way is to lower running speed. Another is to take longer rest periods following a run.
