There are approximately 75 different causes of heel pain. At least 80% of all heel pain is due to heel spurs. A heel spur contains calcium, but cannot truly be called a calcium deposit. Bone spurs, whether they are on the heel or on any other bone of the body, are true bone — they are true enlargements of the bone and may be sharp and pointed, or round and knobby. Since bone spurs are true bone, they contain calcium just like regular bones, but are not pure calcium deposits.
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.
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.
The proper diagnosis of a heel spur often requires an X-ray. To make this process as convenient for his patients as possible, most clinics have an on-site digital X-ray and diagnostic ultrasound machines. This can make it unnecessary for patients to visit diagnostic imaging centers, allowing patients to receive more expedient treatment.
Non Surgical Treatment
Heel pain may be associated with a heel spur, however the heel pain is usually due to plantar fasciitis, rather than a heel spur, so treatment is usually directed at the plantar fasciitis itself. Treatment usually involves application of ice to reduce pain and inflammation, special stretching exercises, and pain-relieving or anti-inflammatory medicines. Night splints or orthotics may be recommended. It may help to avoid the activities that aggravate pain, such as long walks and running. Surgery is very rarely recommended and only after other measures fail.
Have surgery if no other treatments work. Before performing surgery, doctors usually give home treatments and improved footwear about a year to work. When nothing else eases the pain, here’s what you need to know about surgical options. Instep plantar fasciotomy. Doctors remove part of the plantar fascia to ease pressure on the nerves in your foot. Endoscopy. This surgery performs the same function as an instep plantar fasciotomy but uses smaller incisions so that you’ll heal faster. However, endoscopy has a higher rate of nerve damage, so consider this before you opt for this option. Be prepared to wear a below-the-knee walking cast to ease the pain of surgery and to speed the healing process. These casts, or “boots,” usually work better than crutches to speed up your recovery time.
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.
