A heel spur is a hook of bone that can form on the heel bone of the foot. Heel spurs are associated with plantar fasciitis. Heel spurs can cause extreme pain in the rearfoot. The pain is most intense while standing or walking. What Causes Heel Spurs? Heel spurs develop as an abnormal growth in the heel bone due to calcium deposits that form when the plantar fascia stretches and pulls away from the heel. The plantar fascia is a ligament located at the bottom of your foot. This stretching of the plantar fascia is usually the result of flat feet or unusually high arches.
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.
Heel spur is characterised by a sharp pain under the heel when getting out of bed in the morning or getting up after sitting for a period of time. Walking around for a while often helps reduce the pain, turning it into a dull ache. However, sports, running or walking long distance makes the condition worse. In some cases swelling around the heel maybe present.
Diagnosis of a heel spur can be done with an x-ray, which will be able to reveal the bony spur. Normally, it occurs where the plantar fascia connects to the heel bone. When the plantar fascia ligament is pulled excessively it begins to pull away from the heel bone. When this excessive pulling occurs, it causes the body to respond by depositing calcium in the injured area, resulting in the formation of the bone spur. The Plantar fascia ligament is a fibrous band of connective tissue running between the heel bone and the ball of the foot. This structure maintains the arch of the foot and distributes weight along the foot as we walk. However, due to the stress that this ligament must endure, it can easily become damaged which commonly occurs along with heel spurs.
Non Surgical Treatment
Elevation of the affected foot and leg at rest may diminish the pain. Applying gentle heat to the painful area may ease the pain by dilating local blood vessels. One also can protect the heel by placing a foam rubber pad in the heel of the shoe. A pad about one-half inch thick will raise the heel, shift the weight of the body forward, and protect the irritated muscles attached to the heel bone. The same effect can be achieved by using adhesive tape to turn the foot inward. Additional treatment may consist of a number of physical therapies, such as diathermy, ultrasound waves and whirlpool baths.
Usually, heel spurs are curable with conservative treatment. If not, heel spurs are curable with surgery, although there is the possibility of them growing back. About 10% of those who continue to see a physician for plantar fascitis have it for more than a year. If there is limited success after approximately one year of conservative treatment, patients are often advised to have surgery.
