Heel spurs are usually under the heel and are generally caused by excessive forces acting on the bone. By far the most common cause of heel spurs is abnormal biomechanics - often the same biomechanics that cause plantar fasciitis. Heel spurs are not a direct cause of heel pain. They grow in response to the forces of the soft tissue pulling on the bone. Any condition where the foot has excessive motion can produce tension within the soft tissues acting on the heel.
At the onset of this condition, pain and swelling become present, with discomfort particularly noted as pushing off with the toes occurs during walking. This movement of the foot stretches the fascia that is already irritated and inflamed. If this condition is allowed to continue, pain is noticed around the heel region because of the newly formed bone, in response to the stress. This results in the development of the heel spur. It is common among athletes and others who run and jump a significant amount.
The vast majority of people who have heel spurs feel the asscociated pain during their first steps in the morning. The pain is quite intense and felt either the bottom or front of the heel bone. Typically, the sharp pain diminishes after being up for a while but continues as a dull ache. The pain characteristically returns when first standing up after sitting for long periods.
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
Over-the-counter or prescription-strength anti-inflammatory medications can help temporarily, but can cause side effects with prolonged use - the most significant being gastrointestinal upset, ulceration and bleeding. Deep tissue massage, taping and other physical therapy modalities can also be helpful. Arch support is highly recommended, either with shoe inserts or custom orthotics made by podiatrists. If pain continues, a steroid injection at the site of pain may be recommended; however, many physicians do not like injecting around the heel. The side effects of steroids injected in this area can be serious and worsen symptoms. Complications can include fat necrosis (death of fatty tissue) of the heel and rupture of the plantar fascia.
Surgery to correct for heel spur syndrome is a common procedure which releases plantar fascia partially from its attachment to the calcaneous (heel bone). This part of the surgery is called a plantar fasciotomy due to the fact the fascia is cut. This is most often done through an open procedure as any heel spur or bursa can be removed at the same time. If the spur is not removed during the surgery, it will probably be just as successful, as the large spur is not the true problem. Some physicians use an endoscopic approach (EPF) where a small camera aids the physician during surgery with typically smaller incisions on each side of your foot.
