A heel spur is an abnormal growth of the heel bone, the largest bone in the foot which absorbs the greatest amount of shock and pressure. 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.
A bone spur forms as the body tries to repair itself by building extra bone. It generally forms in response to pressure, rubbing, or stress that continues over a long period of time. Some bone spurs form as part of the aging process. As we age, the slippery tissue called cartilage that covers the ends of the bones within joints breaks down and eventually wears away (osteoarthritis). Bone spurs due to aging are especially common in the joints of the spine and feet.
Heel spur and plantar fasciitis pain usually begins in the bottom of the heel, and frequently radiates into the arch. At times, however, the pain may be felt only in the arch. The pain is most intense when first standing, after any period of rest. Most people with this problem experience their greatest pain in the morning, with the first few steps after sleeping. After several minutes of walking, the pain usually becomes less intense and may disappear completely, only to return later with prolonged walking or standing. If a nerve is irritated due to the swollen plantar fascia, this pain may radiate into the ankle. In the early stages of Heel Spurs and Plantar Fasciitis, the pain will usually subside quickly with getting off of the foot and resting. As the disease progresses, it may take longer periods of time for the pain to subside.
A Heel Spur diagnosis is made when an X-ray shows a hook of bone protruding from the bottom of the foot at the point where the plantar fascia is attached to the heel bone. The plantar fascia is the thick, connective tissue that runs from the calcaneus (heel bone) to the ball of the foot. This strong and tight tissue helps maintain the arch of the foot. It is also one of the major transmitters of weight across the foot as you walk or run. In other words, tremendous stress is placed on the plantar fascia.
Non Surgical Treatment
Diathermy treatment uses an electrical current to produce heat that sedates the inflamed tissues. The ultrasound device sends sound waves into the heel and sets up a massaging action that stimulates blood circulation. Treatment with a whirlpool bath involves placing the foot directly into the jetting stream. Orthopedic molds and appliances, such as orthotics, are designed by foot specialists for use inside the shoe to eliminate irritation to the heel when the patient stands or walks. When those appliances are used, the spur (in effect) floats on air. At the same time, the body's weight is transferred forward from the tender spot.
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.
Heel Spur symptoms can be prevented from returning by wearing proper shoes and using customized orthotics and insoles to relieve pressure. It is important to perform your exercises to help keep your foot stretched and relaxed.
