Heel spurs, or abnormal growths of the heel bone, can cause sharp pains in the heel, especially first thing in the morning and after long periods of rest. In many cases, a heel spur develops as a result of plantar fasciitis, which is the inflammation of the ligament that stretches along the bottom of the foot, from the base of the toes to the heel. In individuals who suffer from plantar fasciitis, the ligament pulls away from the heel as the foot bears weight. In an effort to stabilize the ligament, the body may produce calcium deposits, which can then develop into heel spurs.
Fctors that increase the risk of developing heel spurs include a high body mass index (BMI), regular vigorous activity, and intensive training routines or sports. Factors such as these are believed to increase the incidence of repetitive stress injuries that are associated with the formation of heel spurs. When a heel spur forms, extremely sharp pain along with the feeling that a part of the heel is trying to burst through the skin usually occurs. If left untreated, an individual may eventually begin to struggle to perform simple activities such as walking.
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.
Heel spurs and plantar fasciitis are diagnosed based on the history of pain and tenderness localized to these areas. They are specifically identified when there is point tenderness at the bottom of the heel, which makes it difficult to walk barefoot on tile or wood floors. X-ray examination of the foot is used to identify the bony prominence (spur) of the heel bone (calcaneus).
Non Surgical Treatment
Initially, treatment usually consists of a combination of ice therapy, stretching exercises to improve flexibility (especially in the mornings), anti-inflammatory medications, and physical therapy. Most patients will also need custom-molded orthotics to help control the motion in the foot and arch, which takes the strain off the plantar fascia. If the pain continues, a cortisone injection may be used to calm the severe swelling and pain. There may the need for a night splint to maintain a stretch in the plantar fascia throughout the night.
Surgery involves releasing a part of the plantar fascia from its insertion in the heel bone, as well as removing the spur. Many times during the procedure, pinched nerves (neuromas), adding to the pain, are found and removed. Often, an inflamed sac of fluid call an accessory or adventitious bursa is found under the heel spur, and it is removed as well. Postoperative recovery is usually a slipper cast and minimal weight bearing for a period of 3-4 weeks. On some occasions, a removable short-leg walking boot is used or a below knee cast applied.
