Heel spurs refer to the abnormal accumulation of calcium deposits on the heel of the foot. Vigorous, repetitive movements often result in the formation of heel spurs, but inflammatory diseases (e.g., arthritis) may also increase the occurrence of painful heel spurs. Treatments that have proven to be effective for heel spurs include injections that contain a combination of steroids and anesthesia as well as radiofrequency ablation. However, a bone spur that begins to protrude excessively may need to be removed through surgery.
Heel spurs are exacerbated by an movements that stretch, twist or impact the plantar ligaments. Running, jumping, standing or walking on hard surfaces with unsupportive shoes, walking barefoot in sand are all activities that can activate heel spurs and plantar fasciitis. Obesity is another factor that increases stress to the plantar ligaments.
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.
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
Treatment of heel spurs is the same as treatment of plantar fasciitis. Because these problems are related, the treatment is the same. The first step in the treatment of a heel spur is short-term rest and inflammation control. Here are the steps patients should take in order to cure the symptoms of plantar fasciitis and heel spurs. Avoiding the activity that caused the symptoms is the first step in treatment. For example, take a few day off jogging or prolonged standing/walking. Just resting usually helps to eliminate the most severe pain, and will allow the inflammation to begin to cool down. Icing will help to diminish some of the symptoms and control the heel pain. Icing is especially helpful after a sudden flare up of symptoms. Exercises and stretches are designed to relax the tissues that surround the heel bone. Some simple exercises, performed in the morning and evening, often help patients feel better quickly. Many patients will work with a physical therapist, or you can try some simple activities on your own. If you need some help, meet with a therapist for a few sessions to learn a program you can continue on your own.
More than 90 percent of people get better with nonsurgical treatments. If conservative treatment fails to treat symptoms of heel spurs after a period of 9 to 12 months, surgery may be necessary to relieve pain and restore mobility. Surgical techniques include release of the plantar fascia, removal of a spur. Pre-surgical tests or exams are required to identify optimal candidates, and it's important to observe post-surgical recommendations concerning rest, ice, compression, elevation of the foot, and when to place weight on the operated foot. In some cases, it may be necessary for patients to use bandages, splints, casts, surgical shoes, crutches, or canes after surgery. Possible complications of heel surgery include nerve pain, recurrent heel pain, permanent numbness of the area, infection, and scarring. In addition, with plantar fascia release, there is risk of instability, foot cramps, stress fracture, and tendinitis.
