Bone spurs usually form around joints that have arthritis, in the vertebrae of the spine, and on the heel. When they form on the heel, they may form on the back of the heel but usually form on the bottom of the heel. Of course, this is where all of the body weight comes down with each step. Spurs on the bottom of the heel are usually most painful the first few steps out of bed each morning. The pain may lessen somewhat after walking for a few minutes, but may be intense again after sitting for a half hour or so, such as after lunch. The pain usually gets worse throughout the day as you are up on your feet more. Often the pain feels like a nail being driven through the heel into the ankle and leg.
One frequent cause of heel spurs is an abnormal motion and mal-alignment of the foot called pronation. For the foot to function properly, a certain degree of pronation is required. This motion is defined as an inward action of the foot, with dropping of the inside arch as one plants the heel and advances the weight distribution to the toes during walking. When foot pronation becomes extreme from the foot turning in and dropping beyond the normal limit, a condition known as excessive pronation creates a mechanical problem in the foot. In some cases the sole or bottom of the foot flattens and becomes unstable because of this excess pronation, especially during critical times of walking and athletic activities. The portion of the plantar fascia attached into the heel bone or calcaneous begins to stretch and pull away from the heel bone.
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.
Heel spurs and plantar fasciitis are diagnosed based on the history of pain and tenderness localized to these areas. They are specifically identified when there is point tenderness at the bottom of the heel, which makes it difficult to walk barefoot on tile or wood floors. X-ray examination of the foot is used to identify the bony prominence (spur) of the heel bone (calcaneus).
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.
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.
