The plantar fascia is connective tissue on the sole of your foot. When the arch of the foot is not properly supported, the plantar fascia can stretch and pull away from the heel area. When the plantar fascia pulls away from the heel, calcium deposits form in its absence. These calcium deposits are called heel spurs and can be very painful.
Everyone can be affected by heel spurs, however, certain groups of people have an increased risk. For example, Plantar Fasciitis is a common running injury. People who walk a lot are much more likely to have heel spurs or people who play golf or play tennis. Over-weight people are also more at risk for heel bone spurs as our feet are not designed to carry around extra weight. As a result the ligaments under the foot are placed under constant stress, which inevitably will lead to foot problems.
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.
Heel spurs and plantar fasciitis are diagnosed based on the history of pain and tenderness localized to these areas. They are specifically identified when there is point tenderness at the bottom of the heel, which makes it difficult to walk barefoot on tile or wood floors. X-ray examination of the foot is used to identify the bony prominence (spur) of the heel bone (calcaneus).
Non Surgical Treatment
To aid in the reduction of inflammation, applying ice for 10-15 minutes after activities and the use of anti-inflammatory medications, such as aspirin or ibuprofen, can be helpful. Corticosteroid injections may also be used to reduce pain and inflammation. Physical therapy can be beneficial with the use of heat modalities, such as ultrasound, that create a deep heat and reduce inflammation. If the pain caused by inflammation is constant, keeping the foot raised above the heart and/or compressed by wrapping with a bandage will help. Taping can help speed the healing process by protecting the fascia from reinjury, especially during stretching and walking.
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.
