A heel spur also known as a calcaneal spur, is a pointed bony outgrowth of the heel bone (calcaneus). Heel spurs do not always cause pain and often are discovered incidentally on X-rays taken for other problems. Heel spurs can occur at the back of the heel and also under the heel bone on the sole of the foot, where they may be associated with the painful foot condition plantar fasciitis.
Heel spurs develop as an abnormal growth in the heel bone due to calcium deposits that form when the plantar fascia pulls away from the heel. This stretching of the plantar fascia is usually the result of over-pronation (flat feet), but people with unusually high arches (pes cavus) can also develop heel spurs. Women have a significantly higher incidence of heel spurs due to the types of footwear often worn on a regular basis.
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 history and physical exam 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
FIRST, Reduce the acute pain. This is done by a combination of several things; injection of a synthetic relative of cortisone into the heel, a prescription of anti-inflammatory pills to reduce inflammation, physical therapy and a special heel pad. About 50% of the time, these treatments will permanently relieve the pain. In the other 50%, the pain becomes recurrent, and the treatment proceeds to Stage II. SECOND, Recurrent, painful heel spur is caused by the tug and pull of the plantar fascia ligament on the heel bone with each step. When the pain is recurrent, arch supports are made to prevent sagging of the arch. The arch supports are custom-made according to the size and shape of the feet. This prevents the arch from sagging and the ligament from tugging and pulling on the heel bone. The inflammation and pain eventually go away as the first phase of treatment is continued along with the arch supports, although the spur itself remains. THIRD, Surgery to remove the spur is possible and is usually done as Day Surgery.
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.
To prevent this condition, wearing properly fitted shoes with good arch support is very important. If a person is overweight, weight loss can help diminish stress on the feet and help prevent foot problems. For those who exercise frequently and intensely, proper stretching is always necessary, especially when there is an increase in activities or a change in running technique. It is not recommended to attempt to work through the pain, as this can change a mild case of heel spurs and plantar fascitis into a long-lasting and painful episode of the condition.
