Overview
A common cause of heel pain is the heel spur, which is a bony growth on the underside of the heel bone. The spur, visible by X-ray, appears as a protrusion that can extend forward as much as half an inch. When there is no indication of bone enlargement, the condition is sometimes referred to as ?heel spur syndrome.?
Heel spurs result from strain on the muscles and ligaments of the foot, by stretching of the long band of tissue that connects the heel and the ball of the foot, and by repeated tearing away of the lining or membrane that covers the heel bone. These conditions may result from biomechanical imbalance, running or jogging, improperly fitted or excessively worn shoes, or obesity. Heel spurs specifically relate to the bony spurs (extra bony growth) that form at the base of the heel. It is a ?spike? of bone that grows from the base of the heel.
Causes
You are more likely to develop plantar fasciitis and heel spurs if you are Active. Sports that place excessive stress on the heel bone and attached tissue, especially if you have tight calf muscles or a stiff ankle from a previous ankle sprain, which limits ankle movement eg. running, ballet dancing and aerobics. Overweight. Carrying around extra weight increases the strain and stress on your plantar fascia. Pregnant. The weight gain and swelling associated with pregnancy can cause ligaments to become more relaxed, which can lead to mechanical problems and inflammation. On your feet. Having a job that requires a lot of walking or standing on hard surfaces ie factory workers, teachers and waitresses. Flat Feet or High Foot Arches. Changes in the arch of your foot changes the shock absorption ability and can stretch and strain the plantar fascia, which then has to absorb the additional force. Middle-Aged or Older. With ageing the arch of your foot may begin to sag - putting extra stress on the plantar fascia. Wearing shoes with poor support. Weak Foot Arch Muscles. Muscle fatigue allows your plantar fascia to overstress and cause injury. Arthritis. Some types of arthritis can cause inflammation in the tendons in the bottom of your foot, which may lead to plantar fasciitis. Diabetes. Although doctors don't know why, plantar fasciitis occurs more often in people with diabetes.
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
Because the diagnosis of heel spurs can be confused with tarsal tunnel syndrome (as described earlier), most surgeons advocate performing a tarsal tunnel release (or at least a partial tarsal tunnel release) along with the plantar fascia release. This surgery is about 80percent successful in relieving pain in the small group of patients who do not improve with conservative treatments.
Non Surgical Treatment
To aid in the reduction of inflammation, applying ice for 10-15 minutes after activities and the use of anti-inflammatory medications, such as aspirin or ibuprofen, can be helpful. Corticosteroid injections may also be used to reduce pain and inflammation. Physical therapy can be beneficial with the use of heat modalities, such as ultrasound, that create a deep heat and reduce inflammation. If the pain caused by inflammation is constant, keeping the foot raised above the heart and/or compressed by wrapping with a bandage will help. Taping can help speed the healing process by protecting the fascia from reinjury, especially during stretching and walking.
Surgical Treatment
In some cases, heel spurs are removed by surgery after an X-ray. While the surgery is typically effective, it?s a timely and expensive procedure. Even after surgery, heel spurs can re-form if the patient continues the lifestyle that led to the problem. These reasons are why most people who develop painful heel spurs begin looking for natural remedies for joint and bone pain. Surgery isn?t required to cure a heel spur. In fact, more than 90 percent of people get better with nonsurgical treatments. If nonsurgical methods fail to treat symptoms of heel spurs after 12 months, surgery may be necessary to alleviate pain and restore mobility.
Prevention
o help prevent heel and bone spurs, wear properly designed and fitted shoes or boots that provide sufficient room in the toe box so as not to compress the toes. They should also provide cushioning in appropriate areas to minimize the possibility of the irritation and inflammation that can lead to bone spurs in the feet. If needed, use inserts that provide arch support and a slight heel lift to help ensure that not too much stress is placed on the plantar fascia. This helps to reduce the possibility of inflammation and overstress. Wearing padded socks can also help by reducing trauma. Peer-reviewed, published studies have shown that wearing clinically-tested padded socks can help protect against injuries to the skin/soft tissue of the foot due to the effects of impact, pressure and shear forces. Also consider getting your gait analyzed by a foot health professional for appropriate orthotics. If you have heel pain, toe pain or top-of-the-foot pain, see your doctor or foot specialist to ensure that a spur has not developed.
