Heel spurs are a small calcification, which extends into the attachment of the connective tissues from the calcaneus (heel bone). This is easily observed on X-Ray and is very commonly misdiagnosed as the cause of your pain. Why? Because the wrong type of scan is used and only one foot is examined. Do you know if you have a spur on the other heel, the heel without the pain? Probably? and the heel spur would have been there long before you had the pain, and will still be there long after the pain is gone. Heel spurs are not the actual cause of heel pain, and are virtually always a secondary observation or symptom caused by long term pulling on the heel bone.
Heel spurs can be caused by several things. Anything that can cause the body to rebuild itself can lead to a bone spur. A heel spur is a natural reaction of the body to correct a weakness by building extra bone. One of the most common causes for the development of heel spurs is the wearing of shoes that are too tight. That?s why more women suffer from heel spurs more than men. Athletes who tend to stress their feet a lot, people are overweight who have more pressure on their lower extremities and the elderly also tend to suffer more from heel spurs.
The spur itself is not painful, however, if it is sharp and pointed it can poke into soft tissue surrounding the spur itself. As the bone spur irritates the tissue, inflammation and bruising can occur leading to heel pain. Heel spurs can affect your ability to do your usual work and/or activities, and can also trap and irritate the nerves in your heel area. They can change the way you walk, and can lead to knee, hip and low back injuries. If severe, they may require medical intervention.
A thorough medical history and physical exam by a physician is always necessary for the proper diagnosis of heel spurs and other foot conditions. X rays of the heel area are helpful, as excess bone production will be visible.
Non Surgical Treatment
Heel spurs can be treated by wearing orthotic insoles inside the shoe. Orthotics are designed to correct incorrect gait, in particular over-pronation (rolling in of the foot and collapsing of the arches). Over-pronation is a very common foot condition, affecting at least half of the population. It is a major contributing cause of heel spurs. Orthotics are very effective in that the device corrects the foot to its natural position. By supporting the arches properly and preventing excess rolling in of the foot, the plantar fascia is placed under much less strain and stress compared to an unsupported foot. Less strain on the ligament means less pulling away from the heel bone, allowing the inflammation to heal faster. In addition to orthotic treatment, most podiatrists and physiotherapists recommend a series of exercises to help make the ligaments in the feet and legs longer and more flexible. In turn this will help reduce strain on the plantar fascia.
Surgery involves releasing a part of the plantar fascia from its insertion in the heel bone, as well as removing the spur. Many times during the procedure, pinched nerves (neuromas), adding to the pain, are found and removed. Often, an inflamed sac of fluid call an accessory or adventitious bursa is found under the heel spur, and it is removed as well. Postoperative recovery is usually a slipper cast and minimal weight bearing for a period of 3-4 weeks. On some occasions, a removable short-leg walking boot is used or a below knee cast applied.
