There are approximately 75 different causes of heel pain. At least 80% of all heel pain is due to heel spurs. A heel spur contains calcium, but cannot truly be called a calcium deposit. Bone spurs, whether they are on the heel or on any other bone of the body, are true bone -- they are true enlargements of the bone and may be sharp and pointed, or round and knobby. Since bone spurs are true bone, they contain calcium just like regular bones, but are not pure calcium deposits.
The cause of heel spurs is excessive strain placed on the plantar fascia over a long period of time, as a result of different factors. These factors include incorrect gait, being overweight, ageing or being in a job that requires a lot of standing on hard floors. It is usually a combination of any of these factors that will bring on the development of heel spurs.
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.
Your doctor will discuss your medical history and will examine your foot and heel for any deformities and inflammation (swelling, redness, heat, pain). He/she will analyze your flexibility, stability, and gait (the way you walk). Occasionally an x-ray or blood tests (to rule out diseases or infections) may be requested.
Non Surgical Treatment
Perform some exercises. Exercises that strengthen and lengthen your plantar fascia can also be very helpful for heel spurs. Try some of the following activities. Calf stretch. Place your hands on a wall. Extend 1 foot (0.3 m) behind you with your knee straight and place the other foot in front of you with the knee bent. Push your hips toward the wall and hold the stretch for 10 seconds. You should feel a pull in your calf muscles. Repeat the stretch 20 times for each foot. Plantar fascia stretch, Perform this exercise in the morning before you've done any standing or walking. Cross your injured foot over the knee of your other leg. Grasp your toes and gently pull them toward you. If you can't reach your toes, then wrap a towel around them and pull on the towel. Hold the stretch for 10 seconds and repeat 20 times for each foot.
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.
