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.
Heel spurs are bony outgrowths positioned where the plantar fascia tissue attaches to the heel bone (the calcaneus). Heel spurs seldom cause pain. It is the inflamed tissue surrounding the spur that causes the pain. The Latin meaning of Plantar Fasciitis is, ?Inflammation of Plantar Fascia.? The plantar fascia is a long, thick and very tough band of tissue beneath your foot that provides arch support. It also connects your toes to your heel bone. Each time you take a step, the arch slightly flattens to absorb impact. This band of tissue is normally quite strong and flexible but unfortunately, circumstances such as undue stress, being overweight, getting older or having irregularities in your foot dynamics can lead to unnatural stretching and micro-tearing of the plantar fascia. This causes pain and swelling at the location where the plantar fascia attaches to the heel bone. As the fascia continually pulls at the heel bone, the constant irritation eventually creates a bony growth on the heel. This is called a heel spur.
Most people think that a bone “spur” is sharp and produces pain by pressing on tissue, when in fact, these bony growths are usually smooth and flat. Although they rarely cause pain on their own, bone spurs in the feet can lead to callus formation as tissue builds up to provide added cushion over the area of stress. Over time, wear and tear on joints may cause these spurs to compress neighboring ligaments, tendons or nerves, thus injuring tissue and causing swelling, pain and tearing.
A heel spur is often seen on X-ray as a bony protrusion, which can vary in size. However, because a Heel Spur only indicates increased load on the plantar fascia, and not pain, an ultra sound may be required to assess other actual cause of the heel pain such and may include checking to see if the plantar fascia is inflamed or degenerated.
Non Surgical Treatment
If pain and other symptoms of inflammation-redness, swelling, heat-persist, you should limit normal daily activities and contact a doctor of podiatric medicine. The podiatric physician will examine the area and may perform diagnostic X-rays to rule out problems of the bone. Early treatment might involve oral or injectable anti-inflammatory medication, exercise and shoe recommendations, taping or strapping, or use of shoe inserts or orthotic devices. Taping or strapping supports the foot, placing stressed muscles and tendons in a physiologically restful state. Physical therapy may be used in conjunction with such treatments. A functional orthotic device may be prescribed for correcting biomechanical imbalance, controlling excessive pronation, and supporting of the ligaments and tendons attaching to the heel bone. It will effectively treat the majority of heel and arch pain without the need for surgery. Only a relatively few cases of heel pain require more advanced treatments or surgery. If surgery is necessary, it may involve the release of the plantar fascia, removal of a spur, removal of a bursa, or removal of a neuroma or other soft-tissue growth.
Most studies indicate that 95% of those afflicted with heel spurs are able to relieve their heel pain with nonsurgical treatments. If you are one of the few people whose symptoms don?t improve with other treatments, your doctor may recommend plantar fascia release surgery. Plantar fascia release involves cutting part of the plantar fascia ligament in order to release the tension and relieve the inflammation of the ligament. Sometimes the bone spur is also removed, if there is a large spur (remember that the bone spur is rarely a cause of pain. Overall, the success rate of surgical release is 70 to 90 percent in patients with heel spurs. One should always be sure to understand all the risks associated with any surgery they are considering.
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.
