A heel spur is caused by the displacement of calcium on the bone that forms on the underside of the heel, it may be one small bony protrusion or a collection of tiny, irregularly shaped growths on the bone of the heel, which is called the calcaneum. Heel spurs are sometimes painful, described as a knife digging into the heel and other times, a heel spur goes unnoticed and is only detected by an X-ray.
When a patient has plantar fasciitis, the plantar fascia becomes inflamed and degenerative (worn out)--these abnormalities can make normal activities quite painful. Symptoms typically worsen early in the morning after sleep. At that time, the plantar fascia is tight so even simple movements stretch the contracted plantar fascia. As you begin to loosen the plantar fascia, the pain usually subsides, but often returns with prolonged standing or walking.
Some symptoms at the beginning of this condition include pain and swelling, and discomfort when pushing off with the toes during walking. This movement of the foot stretches the fascia that is already irritated and inflamed. If this condition is not treated, pain will be noticed in the heel when a heel spur develops in response to the stress. This is a common condition among athletes and others who run and jump a significant amount.
Your doctor will discuss your medical history and will examine your foot and heel for any deformities and inflammation (swelling, redness, heat, pain). He/she will analyze your flexibility, stability, and gait (the way you walk). Occasionally an x-ray or blood tests (to rule out diseases or infections) may be requested.
Non Surgical Treatment
The key is to identify what is causing excessive stretching of the plantar fascia. When the cause is over-pronation (flat feet), an orthotic with rearfoot posting and longitudinal arch support will help reduce the over-pronation and thus allow the condition to heal. Other common treatments for heel spurs include Stretching exercises. Losing weight. Wearing shoes that have a cushioned heel that absorbs shock. Elevating the heel with the use of a heel cradle, heel cup, or orthotics. For example, heel cradles and heel cups provide extra comfort and cushion to the heel, reducing the amount of shock and shear forces experienced from everyday activities.
Sometimes bone spurs can be surgically removed or an operation to loosen the fascia, called a plantar fascia release can be performed. This surgery is about 80 percent effective in the small group of individuals who do not have relief with conservative treatment, but symptoms may return if preventative measures (wearing proper footwear, shoe inserts, stretching, etc) are not maintained.
You can prevent heel spurs by wearing well-fitting shoes with shock-absorbent soles, rigid shanks, and supportive heel counters; choosing appropriate shoes for each physical activity; warming up and doing stretching exercises before each activity; and pacing yourself during the activities. Avoid wearing shoes with excessive wear on the heels and soles. If you are overweight, losing weight may also help prevent heel spurs.
