Overview
A heel spur is a hooked bony growth protruding from the calcaneus or heel bone. It often occurs alongside plantar fasciitis, and as such the two conditions are often confused, however they are not the same.
Causes
A strong band of sinew (plantar fascia) stretches across the sole of the foot below the surface of the skin and is attached to a point in the middle of the under surface of the heel bone. With repeated activity on our feet, the plantar fascia can become tight and cause persistent traction (tugging) on its attachment point into the heel bone, and inflammation and pain may develop at this site. This painful condition is known as plantar fasciitis. Sometimes a ?spur? develops at the site of this traction on the bone and protrudes into the surrounding tissue. This is a heel spur.
Symptoms
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.
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
A conventional treatment for a heel spur is a steroid injection. This treatment, however, isn?t always effective because of the many structures in the heel, making it a difficult place for an injection. If this treatment goes wrong, it can make the original symptoms even worse. Another interesting means of treatment is Cryoultrasound, an innovative electromedical device that utilizes the combination of two therapeutic techniques: cryotherapy and ultrasound therapy. Treatments with Cryoultrasound accelerate the healing process by interrupting the cycle and pain and spasms. This form of therapy increases blood circulation and cell metabolism; it stimulates toxin elimination and is supposed to speed up recovery.
Surgical Treatment
Approximately 2% of people with painful heel spurs need surgery, meaning that 98 out of 100 people do well with the non-surgical treatments previously described. However, these treatments can sometimes be rather long and drawn out, and may become considerably expensive. Surgery should be considered when conservative treatment is unable to control and prevent the pain. If the pain goes away for a while, and continues to come back off and on, despite conservative treatments, surgery should be considered. If the pain really never goes away, but reaches a plateau, beyond which it does not improve despite conservative treatments, surgery should be considered. If the pain requires three or more injections of "cortisone" into the heel within a twelve month period, surgery should be considered.
