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.
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.
The Heel Spur itself is not thought to be painful. Patients who experience pain with Plantar Fasciitis are suffering from inflammation and irritation of the plantar fascia. This the primary cause of pain and not the Heel Spur. Heel Spurs form in some patients who have plantar fasciitis, and tend to occur in patients who have had the problem for a prolonged period of time. While about 70 % of patients with plantar fasciitis have a heel spur, X-rays also show about 50 % of patients with no symptoms of plantar fasciitis also have a heel spur.
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
Ice and use arch support . If you can localize the spur, cut a hole in a pad of felt and lay the hole over the spur. This supports the area around the spur and reduces pressure on it. Massage the spur. Start gently with your thumb and gradually increase the pressure until you?re pushing hard directly on the spur with your knuckle or another firm object. Even it if hurts, it should help. Arch support. Build up an arch support system in your shoes. Try to equalize the pressure of your body weight throughout your arch and away from the plantar area. Use a ?cobra pad? or other device that supports the arch but releases pressure on the painful area. If homemade supports do not work, see a podiatrist about custom orthotics.
Sometimes bone spurs can be surgically removed or an operation to loosen the fascia, called a plantar fascia release can be performed. This surgery is about 80 percent effective in the small group of individuals who do not have relief with conservative treatment, but symptoms may return if preventative measures (wearing proper footwear, shoe inserts, stretching, etc) are not maintained.
