Bone spurs usually form around joints that have arthritis, in the vertebrae of the spine, and on the heel. When they form on the heel, they may form on the back of the heel but usually form on the bottom of the heel. Of course, this is where all of the body weight comes down with each step. Spurs on the bottom of the heel are usually most painful the first few steps out of bed each morning. The pain may lessen somewhat after walking for a few minutes, but may be intense again after sitting for a half hour or so, such as after lunch. The pain usually gets worse throughout the day as you are up on your feet more. Often the pain feels like a nail being driven through the heel into the ankle and leg.
Faulty foot structures such as abnormal growths, different leg lengths, and unhealed injuries and haveinf flat feet or high arches. Muscle imbalances tight, weak or shortened muscles in your foot, plantar fascia, ankle, calf and hamstring. Over pronation can cause imbalance in foot mechanics which puts excess pressure on the plantar fascia. Poor biomechanics affect the way your foot hits the ground. If you overpronate (feet roll inward) you tend to have flat feet (pes planus), which increases stress on the heel bone. Regular shoes or high heels that are too tight or don't support your heel or arch affect the distribution of your body weight on your foot. Health conditions such as obesity, inflammatory diseases (rheumatoid arthritis, ankylosing spondylitis), bursitis, neuroma (nerve growths), gout, diabetes, Haglund's deformity, and Achilles tendinitis can also instigate the problem. Running or jogging on hard surfaces, repetative striking of the heel bone.
Although it may take years to become a problem, once it appears, it may cause considerable suffering. Because of proximity to the tendons, the spur is a source of continuous painful aching. The sensation has been described as "a toothache in the foot." When you place your weight on the heel, the pain can be sufficient to immobilize you.
A thorough medical history and physical exam by a physician is always necessary for the proper diagnosis of heel spurs and other foot conditions. X rays of the heel area are helpful, as excess bone production will be visible.
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.
There are heel spur prevention methods available in order to prevent the formation of a heel spur. First, proper footwear is imperative. Old shoes or those that do not fit properly fail to absorb pressure and provide the necessary support. Shoes should provide ample cushioning through the heel and the ball of the foot, while also supporting the arch. Wearing an orthotic shoe insert is one of the best ways to stretch the plantar fascia and prevent conditions such as heel spurs. Stretching the foot and calf is also helpful in preventing damage. Athletes in particular should make sure to stretch prior to any physical activity. Stretching helps prevent heel spurs by making tissue stronger as well as more flexible. In addition, easing into a new or increasingly difficult routine should be done to help avoid strain on the heel and surrounding tissue.
