Bone spurs (retrocalcaneal spur, or exostosis) can develop not only on the back of the heel, but also on the toes, mainly around the fifth (small) toe. Most often, they occur next to the toenail on the outside of the toe; on the inside of the toe near the tip, where the fifth toe presses against the fourth toe; and on the inside of the base of the toe. Bone spurs can also occur on the sides of the toes. This is usually due to wearing shoes that are too tight in the toe box, which causes the toes to press against each other. Bone spurs may also develop in the arch area of the top of the foot; this area becomes painful when you tie your shoelaces tightly or exert other pressure on that part of the foot. Formation of spurs in this area is often associated with arthritis.
Over-pronation (flat feet) is a common cause of heel spurs, but people with unusually high arches (pes cavus) can also develop heel spurs. Women have a significantly higher incidence of heel spurs due to the types of footwear often worn on a regular basis.
Symptoms may be similar to those of plantar fasciitis and include pain and tenderness at the base of the heel, pain on weight bearing and in severe cases difficulty walking. The main diagnosis of a heel spur is made by X-ray where a bony growth on the heel can be seen. A heel spur can occur without any symptoms at all and the athlete would never know they have the bony growth on the heel. Likewise, Plantar fasciitis can occur without the bone growth present.
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
The key for the proper treatment of heel spurs is determining what is causing the excessive stretching of the plantar fascia. When the cause is over-pronation (flat feet), an orthotic with rearfoot posting and longitudinal arch support is an effective device to reduce the over-pronation, and allow the condition to heal. Other common treatments include stretching exercises, losing weight, wearing shoes that have a cushioned heel that absorbs shock, and elevating the heel with the use of a heel cradle, heel cup, or orthotic. Heel cradles and heel cups provide extra comfort and cushion to the heel, and reduce the amount of shock and shear forces experienced from everyday activities.
In a small number of cases (usually less than 5 percent), patients may not experience relief after trying the recommendations listed above. It is important that conservative treatments (such as those listed above) be performed for AT LEAST a year before considering surgery. Time is important in curing the pain from heel spurs, and insufficient treatment before surgery may subject you to potential complications from the procedure. If these treatments fail, your doctor may consider an operation to loosen the plantar fascia, called a plantar fascia release.
