When the body is under stress or constent inflammation it will deposit calcium to our bones. This added 'bone growth' is designed to relieve the added stress/pressure to our connective tissue. In the case of a heel spur, added calcium to the heel bone (calcaneus). It usually forms at the bottom underside of the heel bone where the plantar fascia attaches. This calcium deposit forms over a period of many months. Heel bones can very in shape and size from person to person. An irregular shape heel (calcaneus) can cause the tissue to twist (plantar ligament and Achilles tendon) or a smaller heel bone will put additional stress on tendons and ligaments.
Bone spurs form in the feet in response to tight ligaments, to activities such as dancing and running that put stress on the feet, and to pressure from being overweight or from poorly fitting shoes. For example, the long ligament on the bottom of the foot (plantar fascia) can become stressed or tight and pull on the heel, causing the ligament to become inflamed (plantar fasciitis). As the bone tries to mend itself, a bone spur can form on the bottom of the heel (known as a ?heel spur?). Pressure at the back of the heel from frequently wearing shoes that are too tight can cause a bone spur on the back of the heel. This is sometimes called a ?pump bump,? because it is often seen in women who wear high heels.
With heel spurs, people often talk about a dull ache which is felt most of the time with episodes of a sharp pain in the center of the heel or on the inside margin of the heel. Often the pain is worse on first rising in the morning and after rest and is aggravated by prolonged weight bearing and thin-soled shoes.
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, which is a more radical treatment, can be a permanent correction to remove the spur itself. If your doctor believes that surgery is indicated, he will recommend an operation - but only after establishing that less drastic methods of treatment are not successful.
