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.
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.
Most patients who are suffering with heel spurs can see them with an X-ray scan. They are normally hooked and extend into the heel. Some people who have heel spur may not even have noticeable symptoms, although could still be able to see a spur in an X-ray scan.
Non Surgical Treatment
Diathermy treatment uses an electrical current to produce heat that sedates the inflamed tissues. The ultrasound device sends sound waves into the heel and sets up a massaging action that stimulates blood circulation. Treatment with a whirlpool bath involves placing the foot directly into the jetting stream. Orthopedic molds and appliances, such as orthotics, are designed by foot specialists for use inside the shoe to eliminate irritation to the heel when the patient stands or walks. When those appliances are used, the spur (in effect) floats on air. At the same time, the body's weight is transferred forward from the tender spot.
Surgery, which is a more radical treatment, can be a permanent correction to remove the spur itself. If your doctor believes that surgery is indicated, he will recommend an operation - but only after establishing that less drastic methods of treatment are not successful.
If you have not yet developed this condition, you can take steps to protect yourself from it. Most importantly, make it a rule to wear properly fitted footwear. Avoid shoes that have become worn down in the heel, and don't choose shoes that cause you to walk in an abnormal fashion. Maintaining a healthy weight will ensure that undue pressure isn't being put on the ligaments, tendons and bones of your feet. If your job requires a great deal of time on your feet, or if you exercise regularly, be sure to balance periods of activity with periods of rest for your feet.
