A heel spur is a bony projection on the sole (plantar) region of the heel bone (also known as the calcaneous). This condition may accompany or result from severe cases of inflammation to the structure called plantar fascia. This associated plantar fascia is a fibrous band of connective tissue on the sole of the foot, extending from the heel to the toes.
One frequent cause of injury to the plantar fascia is pronation. Pronation is defined as the inward and downward action of the foot that occurs while walking, so that the foot's arch flattens toward the ground (fallen arch). A condition known as excessive pronation creates a mechanical problem in the foot, and the portion of the plantar fascia attached to the heel bone can stretch and pull away from the bone. This damage can occur especially while walking and during athletic activities.
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.
Your doctor will review your medical history and examine your foot. X-rays are used to identify the location and size of the heel spur.
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.
More than 90 percent of people get better with nonsurgical treatments. If conservative treatment fails to treat symptoms of heel spurs after a period of 9 to 12 months, surgery may be necessary to relieve pain and restore mobility. Surgical techniques include release of the plantar fascia, removal of a spur. Pre-surgical tests or exams are required to identify optimal candidates, and it's important to observe post-surgical recommendations concerning rest, ice, compression, elevation of the foot, and when to place weight on the operated foot. In some cases, it may be necessary for patients to use bandages, splints, casts, surgical shoes, crutches, or canes after surgery. Possible complications of heel surgery include nerve pain, recurrent heel pain, permanent numbness of the area, infection, and scarring. In addition, with plantar fascia release, there is risk of instability, foot cramps, stress fracture, and tendinitis.
