Approximately 10 per cent of the population may have heel spurs without any heel pain. Whilst recent research has raised the question of whether or not heel spurs are the result of the body trying to increase its base of support, heel spurs are still considered to be the result from strain on the muscles of the foot (in particular the plantar fascia). This may result from a biomechanical imbalance, such as over pronation.
A heel spur is a bony overgrowth on the bottom of your heel bone. The heel spur is usually a result of an inflamed ligament (plantar fascia) on the bottom of the foot that attaches to the heel bone. Constant abnormal pulling of this ligament irritates the heel bone and the body lays down a bone spur as a protective mechanism. The patient usually complains of pain with the first step in the morning, some relief following activity, but returning after extended amounts of time standing or walking.
Heel spurs are most noticeable in the morning when stepping out of bed. It can be described as sharp isolated pain directly below the heel. If left untreated heel spurs can grow and become problematic long-term.
Most patients who are suffering with heel spurs can see them with an X-ray scan. They are normally hooked and extend into the heel. Some people who have heel spur may not even have noticeable symptoms, although could still be able to see a spur in an X-ray scan.
Non Surgical Treatment
The key for the proper treatment of heel spurs is determining what is causing the excessive stretching of the plantar fascia. When the cause is over-pronation (flat feet), an orthotic with rearfoot posting and longitudinal arch support is an effective device to reduce the over-pronation, and allow the condition to heal. Other common treatments include stretching exercises, losing weight, wearing shoes that have a cushioned heel that absorbs shock, and elevating the heel with the use of a heel cradle, heel cup, or orthotic. Heel cradles and heel cups provide extra comfort and cushion to the heel, and reduce the amount of shock and shear forces experienced from everyday activities.
Surgery to correct for heel spur syndrome is a common procedure which releases plantar fascia partially from its attachment to the calcaneous (heel bone). This part of the surgery is called a plantar fasciotomy due to the fact the fascia is cut. This is most often done through an open procedure as any heel spur or bursa can be removed at the same time. If the spur is not removed during the surgery, it will probably be just as successful, as the large spur is not the true problem. Some physicians use an endoscopic approach (EPF) where a small camera aids the physician during surgery with typically smaller incisions on each side of your foot.
Heel Spur symptoms can be prevented from returning by wearing proper shoes and using customized orthotics and insoles to relieve pressure. It is important to perform your exercises to help keep your foot stretched and relaxed.
