Heel spur is a hook of bone that protrudes from the bottom of the foot where plantar fascia connects to the heel bone. Pain associated with heel spurs is usually pain from plantar fasciitis, not the actual bone. Heel spurs are most often diagnosed when a patient has visited a pain specialist or podiatrist for on-going foot pain related to plantar fasciitis; spurs are diagnosed via X-ray of the foot. Heel spurs are most commonly diagnosed in middle-aged men and women. As noted, most patients with this condition have other podiatry-related pain. This condition is a result of plantar fasciitis (when the fascia, a thick connective tissue that connects the heel bone and ball of the foot) becomes inflamed. Some 70% of plantar fasciitis patients have a bone spur. Bone spurs are soft calcium deposits caused from tension in the plantar fascia. When found on an X-ray, they are used as evidence that a patient is suffering from plantar fasciitis. Plantar fasciitis is typically caused from repetitive stress disorder. Walking, running, and dancing can cause this with time.
These bony protrusions are commonly found in association with a condition called Plantar Fasciitis. Plantar Fasciitis occurs when the plantar fascia ligament, which spans the arch of the foot, becomes stressed, torn and inflamed. Misalignment and excessive movement of the plantar fascia ligament is most typically the result of an abnormal walking gait. The ligament is designed to stretch with the bounce of each step you take, but if it stretches too much, the resulting small tears and inflammation can cause mild to extreme discomfort. At the same time, it is believed that heel spurs are formed as the body attempts to provide some additional support to the over-stretched ligament. In other words, calcium builds up as a prop to the plantar fascia.
If your body has created calcium build-ups in an effort to support your plantar fascia ligament, each time you step down with your foot, the heel spur is being driven into the soft, fatty tissue which lines the bottom of your heel. Heel spur sufferers experience stabbing sensations because the hard protrusion is literally being jabbed into the heel pad. If left untreated, Plantar Fasciitis and heel spurs can erode the fatty pad of the heel and cause permanent damage to the foot. Fortunately, most cases can be resolved without medications or surgeries.
Sharp pain localized to the heel may be all a doctor needs to understand in order to diagnose the presence of heel spurs. However, you may also be sent to a radiologist for X-rays to confirm the presence of heel spurs.
Non Surgical Treatment
Bone spurs rarely require treatment unless they are causing frequent pain or damaging other tissues. Because heel spurs and plantar fasciitis are so closely related, they are usually treated the same way. Symptomatic treatment involves rest, especially from the activity that is contributing to the condition and making symptoms worse (although this may not be easy to discover, as problems can manifest several hours or days after the harmful activity has occurred). If you identify the offending activity, ice is recommended immediately following it. Stretching of the calf muscles after a short warm up is also a good idea and can be helpful. Stretching exercises that gently lengthen the calm muscle will relax the tissue surrounding the heel and should be done several times a day, especially in the morning and after prolonged sitting.
Sometimes bone spurs can be surgically removed or an operation to loosen the fascia, called a plantar fascia release can be performed. This surgery is about 80 percent effective in the small group of individuals who do not have relief with conservative treatment, but symptoms may return if preventative measures (wearing proper footwear, shoe inserts, stretching, etc) are not maintained.
