A heel spur is a bony projection on the sole (bottom) of the heel bone. This condition may accompany or result from severe cases of inflammation to the structure called plantar fascia. The plantar fascia is a fibrous band of connective tissue on the sole of the foot, extending from the heel to the toes. Heel spurs are a common foot problem resulting from excess bone growth on the heel bone. The bone growth is usually located on the underside of the heel bone, and may extend forward toward the toes. A painful tear in the plantar fascia between the toes and heel can produce a heel spur and/or inflammation of the plantar fascia. Because this condition is often correlated to a decrease in the arch of the foot, it is more prevalent after the ages of six to eight years, when the arch is fully developed.
A major cause of heel spur pain comes from the development of new fibrous tissue around the bony spur, which acts as a cushion over the area of stress. As this tissue grows, a callus forms and takes up even more space than the heel spur, leading to less space for the thick surrounding network of tendons, nerves, ligaments and supporting tissue. These important structures in the foot have limited space because of calcium or tissue buildup, which leads to swelling and redness of the foot, and a deep throbbing pain worsened with exercise.
Bone spurs may cause sudden, severe pain when putting weight on the affected foot. Individuals may try to walk on their toes or ball of the foot to avoid painful pressure on the heel spur. This compensation during walking or running can cause additional problems in the ankle, knee, hip, or back.
Your doctor will discuss your medical history and will examine your foot and heel for any deformities and inflammation (swelling, redness, heat, pain). He/she will analyze your flexibility, stability, and gait (the way you walk). Occasionally an x-ray or blood tests (to rule out diseases or infections) may be requested.
Non Surgical Treatment
A conventional treatment for a heel spur is a steroid injection. This treatment, however, isn?t always effective because of the many structures in the heel, making it a difficult place for an injection. If this treatment goes wrong, it can make the original symptoms even worse. Another interesting means of treatment is Cryoultrasound, an innovative electromedical device that utilizes the combination of two therapeutic techniques: cryotherapy and ultrasound therapy. Treatments with Cryoultrasound accelerate the healing process by interrupting the cycle and pain and spasms. This form of therapy increases blood circulation and cell metabolism; it stimulates toxin elimination and is supposed to speed up recovery.
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.
