Overview
Heel spurs are a small calcification, which extends into the attachment of the connective tissues from the calcaneus (heel bone). This is easily observed on X-Ray and is very commonly misdiagnosed as the cause of your pain. Why? Because the wrong type of scan is used and only one foot is examined. Do you know if you have a spur on the other heel, the heel without the pain? Probably? and the heel spur would have been there long before you had the pain, and will still be there long after the pain is gone. Heel spurs are not the actual cause of heel pain, and are virtually always a secondary observation or symptom caused by long term pulling on the heel bone.
Causes
Each time we take a step forward, all of our body weight first rests on the heel of one foot. As our weight moves forward, the entire foot begins to bear the body's weight, and the foot flattens and this places a great deal of pressure and strain on the plantar fascia. There is very little ?give? to the plantar fascia, so as it stretches only slightly, it pulls on its attachment to the heel. If the foot is properly aligned this pull causes no problems. However, if the foot is ?pronated?(the foot rolls outward at the ankle, causing a break down of the inner side of the shoe), the arch falls excessively, and this causes an abnormal stretching of the relatively inflexible plantar fascia, which in turn pulls abnormally hard on the heel. The same pathology occurs with ?supination? (the rolling inward of the foot, causing a break down of the outer side of the shoe). Supinated feet are relatively inflexible; usually have a high arch, and a short or tight plantar fascia. Thus as weight is transferred from the heel to the remainder of the foot, the tight plantar fascia hardly stretches at all, and pulls with great force on its attachment to the heel. In both cases, the abnormal stress placed on the attachment of the plantar fascia to the heel usually causes pain, inflammation, and possibly swelling. If this process continues, the plantar fascia partially tears away from the heel. The body will fill in this torn area with calcium; eventually it becomes bone, and a heel spur results.
Symptoms
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.
Diagnosis
Your doctor will review your medical history and examine your foot. X-rays are used to identify the location and size of the heel spur.
Non Surgical Treatment
Since heel spurs are not an indication of pain themselves unless fractured, treatment is usually aimed at the cause of the pain which in many cases is plantar fasciosis. Treatment of plantar fasciiosis includes; rest until the pain subsides, special stretching exercises and if required orthotics may be prescribed.
Surgical Treatment
When chronic heel pain fails to respond to conservative treatment, surgical treatment may be necessary. Heel surgery can provide relief of pain and restore mobility. The type of procedure used is based on examination and usually consists of releasing the excessive tightness of the plantar fascia, called a plantar fascia release. Depending on the presence of excess bony build up, the procedure may or may not include removal of heel spurs. Similar to other surgical interventions, there are various modifications and surgical enhancements regarding surgery of the heel.
