A heel spur is a bony projection on the sole (bottom) of the heel bone. This condition may accompany or result from severe cases of inflammation to the structure called plantar fascia. The plantar fascia is a fibrous band of connective tissue on the sole of the foot, extending from the heel to the toes. Heel spurs are a common foot problem resulting from excess bone growth on the heel bone. The bone growth is usually located on the underside of the heel bone, and may extend forward toward the toes. A painful tear in the plantar fascia between the toes and heel can produce a heel spur and/or inflammation of the plantar fascia. Because this condition is often correlated to a decrease in the arch of the foot, it is more prevalent after the ages of six to eight years, when the arch is fully developed.
There exists a membrane that covers most of the bone along the heel. When this membrane gets torn repeatedly due to straining of the muscles in the foot, the calcium deposits that lead to heel spurs are more likely to occur.
Although it may take years to become a problem, once it appears, it may cause considerable suffering. Because of proximity to the tendons, the spur is a source of continuous painful aching. The sensation has been described as “a toothache in the foot.” When you place your weight on the heel, the pain can be sufficient to immobilize you.
A thorough medical history and physical exam by a physician 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
Only in rare cases do the symptoms of heel spurs fail to be resolved through conservative treatment. Conservative treatment, although not 100% effective, is successful in most cases and should be given ample time to work. In many cases, conservative methods should be utilized as long as a year depending on the rate at which your body responds to the treatment. When treatment is unsuccessful, surgery may be considered. A common surgical procedure for this condition is plantar fascia release surgery. In this procedure, the tension of the plantar fascia ligament is released, lessening tension in the heel and helping to prevent damage.
Heel spur surgery should only be considered after less invasive treatment methods have been explored and ruled insufficient. The traditional surgical approach to treating heel spurs requires a scalpel cut to the bottom of the food which allows the surgeon to access the bone spur. Endoscopic plantar fasciotomies (EPF) involve one or two small incisions in the foot which allow the surgeon to access and operate on the bone spur endoscopically. Taking a surgical approach to heel spur treatment is a topic to explore with a foot and ankle specialist.
There are heel spur prevention methods available in order to prevent the formation of a heel spur. First, proper footwear is imperative. Old shoes or those that do not fit properly fail to absorb pressure and provide the necessary support. Shoes should provide ample cushioning through the heel and the ball of the foot, while also supporting the arch. Wearing an orthotic shoe insert is one of the best ways to stretch the plantar fascia and prevent conditions such as heel spurs. Stretching the foot and calf is also helpful in preventing damage. Athletes in particular should make sure to stretch prior to any physical activity. Stretching helps prevent heel spurs by making tissue stronger as well as more flexible. In addition, easing into a new or increasingly difficult routine should be done to help avoid strain on the heel and surrounding tissue.
