Overview
Heel spurs usually form under the base of the foot or the back of the heel bone. Spurs that develop underneath the foot may visibly protrude through the skin. In addition, plantar fasciitis as well as heel spurs may eventually lead to chronic pain that persists for three or more months, especially if the sides and base of the heel bone have been affected. A large heel spur can affect movement and prevent an individual from walking or even standing properly. If a heel spur begins to protrude excessively, then surgery usually becomes necessary.
Causes
Diseases such as arthritis may lead to chronic inflammation in the tissue surrounding the heel and over time this can lead to the accumulation of calcium deposits. Ankylosing spondylitis, for example, is one particular form of arthritis that frequently develops along with heel spurs. This condition can damage bones all over the body and even lead to the fusion of spinal vertebrae.
Symptoms
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.
Diagnosis
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
Heel spurs and plantar fascitis are usually controlled with conservative treatment. Early intervention includes stretching the calf muscles while avoiding re-injuring the plantar fascia. Decreasing or changing activities, losing excess weight, and improving the proper fitting of shoes are all important measures to decrease this common source of foot pain. Modification of footwear includes shoes with a raised heel and better arch support. Shoe orthotics recommended by a healthcare professional are often very helpful in conjunction with exercises to increase strength of the foot muscles and arch. The orthotic prevents excess pronation and lengthening of the plantar fascia and continued tearing of this structure. To aid in this reduction of inflammation, applying ice for 10-15 minutes after activities and use of anti-inflammatory medication can be helpful. Physical therapy can be beneficial with the use of heat modalities, such as ultrasound that creates a deep heat and reduces inflammation. If the pain caused by inflammation is constant, keeping the foot raised above the heart and/or compressed by wrapping with an ace bandage will help. Corticosteroid injections are also frequently used to reduce pain and inflammation. Taping can help speed the healing process by protecting the fascia from reinjury, especially during stretching and walking.
Surgical Treatment
Usually, heel spurs are curable with conservative treatment. If not, heel spurs are curable with surgery, although there is the possibility of them growing back. About 10% of those who continue to see a physician for plantar fascitis have it for more than a year. If there is limited success after approximately one year of conservative treatment, patients are often advised to have surgery.
Prevention
To prevent this condition, wearing properly fitted shoes with good arch support is very important. If a person is overweight, weight loss can help diminish stress on the feet and help prevent foot problems. For those who exercise frequently and intensely, proper stretching is always necessary, especially when there is an increase in activities or a change in running technique. It is not recommended to attempt to work through the pain, as this can change a mild case of heel spurs and plantar fascitis into a long-lasting and painful episode of the condition.
