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, extending forward to the toes. One explanation for this excess production of bone is a painful tearing of the plantar fascia connected between the toes and heel. This can result in either a heel spur or an inflammation of the plantar fascia, medically termed plantar fascitis. Because this condition is often correlated to a decrease in the arch of the foot, it is more prevalent after the age of six to eight years, when the arch is fully developed.
Causes of Heel Spur Syndrome are mostly due to your foot structure. Foot structure is due to hereditary for the most part, meaning it was the way you were when born. Other factors such as increase in weight, injury, improper shoes, or different activities may change the way your foot functions as well. If one leg is longer or shorter than the other, this may make your foot function improperly and be the cause of the heel spur syndrome. Improper shoes may be ones that are new or ones that are worn out and do not give good support. The higher priced shoes do not mean it's a better shoe. Pronation is a term used to describe a foot which allows the arch to fall more than normal and allows for the fascia along the bottom of the foot to put a tighter pull or a different angle of pull on the heel bone. Over time, this constant pull of the tight fascia can force the bone to enlarge and form a spur. It is not the heel spur that causes the pain directly. The spur may cause pressure against a nearby nerve causing a neuritis, or a bursa causing a bursitis.
The spur itself is not painful, however, if it is sharp and pointed it can poke into soft tissue surrounding the spur itself. As the bone spur irritates the tissue, inflammation and bruising can occur leading to heel pain. Heel spurs can affect your ability to do your usual work and/or activities, and can also trap and irritate the nerves in your heel area. They can change the way you walk, and can lead to knee, hip and low back injuries. If severe, they may require medical intervention.
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
If pain and other symptoms of inflammation-redness, swelling, heat-persist, you should limit normal daily activities and contact a doctor of podiatric medicine. The podiatric physician will examine the area and may perform diagnostic X-rays to rule out problems of the bone. Early treatment might involve oral or injectable anti-inflammatory medication, exercise and shoe recommendations, taping or strapping, or use of shoe inserts or orthotic devices. Taping or strapping supports the foot, placing stressed muscles and tendons in a physiologically restful state. Physical therapy may be used in conjunction with such treatments. A functional orthotic device may be prescribed for correcting biomechanical imbalance, controlling excessive pronation, and supporting of the ligaments and tendons attaching to the heel bone. It will effectively treat the majority of heel and arch pain without the need for surgery. Only a relatively few cases of heel pain require more advanced treatments or surgery. If surgery is necessary, it may involve the release of the plantar fascia, removal of a spur, removal of a bursa, or removal of a neuroma or other soft-tissue growth.
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.
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.
