The heel bone is the largest bone in the foot and absorbs the most amount of shock and pressure. A heel spur develops as an abnormal growth of the heel bone. Calcium deposits form when the plantar fascia pulls away from the heel area, causing a bony protrusion, or heel spur to develop. The plantar fascia is a broad band of fibrous tissue located along the bottom surface of the foot that runs from the heel to the forefoot. Heel spurs can cause extreme pain in the rearfoot, especially while standing or walking.
Athletes who participate in sports that involve a significant amount of jumping and running on hard surfaces are most likely to suffer from heel spurs. Some other risk factors include poor form while walking which can lead to undue stress on the heel and its nerves and ligaments. Shoes that are not properly fitted for the wearer?s feet. Poor arch support in footwear. Being overweight. Occupations that require a lot of standing or walking. Reduced flexibility and the thinning of the fat pad along the bottom of the heel, both of which are a typical depreciation that comes with aging.
An individual with the lower legs turning inward, a condition called genu valgus or "knock knees," can have a tendency toward excessive pronation. This can lead to a fallen arch and problems with the plantar fascia and heel spurs. Women tend to suffer from this condition more than men. Heel spurs can also result from an abnormally high arch. Other factors leading to heel spurs include a sudden increase in daily activities, an increase in weight, or a thinner cushion on the bottom of the heel due to old age. A significant increase in training intensity or duration may cause inflammation of the plantar fascia. High-heeled shoes, improperly fitted shoes, and shoes that are too flexible in the middle of the arch or bend before the toe joints will cause problems with the plantar fascia and possibly lead to heel spurs.
Most patients who are suffering with heel spurs can see them with an X-ray scan. They are normally hooked and extend into the heel. Some people who have heel spur may not even have noticeable symptoms, although could still be able to see a spur in an X-ray scan.
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.
