Avoiding Heel Spur

Inferior Calcaneal Spur

Overview

Heel spurs refer to the abnormal accumulation of calcium deposits on the heel of the foot. Vigorous, repetitive movements often result in the formation of heel spurs, but inflammatory diseases (e.g., arthritis) may also increase the occurrence of painful heel spurs. Treatments that have proven to be effective for heel spurs include injections that contain a combination of steroids and anesthesia as well as radiofrequency ablation. However, a bone spur that begins to protrude excessively may need to be removed through surgery.

Causes

A bone spur forms as the body tries to repair itself by building extra bone. It generally forms in response to pressure, rubbing, or stress that continues over a long period of time. Some bone spurs form as part of the aging process. As we age, the slippery tissue called cartilage that covers the ends of the bones within joints breaks down and eventually wears away (osteoarthritis). Bone spurs due to aging are especially common in the joints of the spine and feet.

Symptoms

Heel spurs result in a jabbing or aching sensation on or under the heel bone. The pain is often worst when you first arise in the morning and get to your feet. You may also experience pain when standing up after prolonged periods of sitting, such as work sessions at a desk or car rides. The discomfort may lessen after you spend several minutes walking, only to return later. Heel spurs can cause intermittent or chronic pain.

Diagnosis

A Diagnosis of Heel Spur Syndrome is a very common reason for having heel pain. Heel pain may be due to other types of conditions such as tendonitis, Haglund's Deformity, Stress Fracture, Tarsal Tunnel Syndrome, or low back problems. A more common condition in children is Sever's Disease. The diagnosis is usually made with a combination of x-ray examination and symptoms.

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.

Surgical Treatment

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.
