What Can Cause Heel Spur
Calcaneal Spur


Overview


A heel spur is a calcium deposit on the underside of the heel bone. Heel spurs are related to plantar fasciitis in that both are caused by irritation and lack of support of the plantar ligaments. Your plantar ligaments are a band of connective tissue that extend along the bottom of the foot and connect your heel bone to the ball of your foot.


Causes


Causes for heel spurs (and related plantar fasciitis) include increase or change in activity, lack of arch support or poor shoe choice, injury, inflexibility in Achilles tendon and calf muscles, and spending hours daily on the feet. Also, arthritis from aging is often a common cause of bone loss and natural cushioning under the heel. Tarsal tunnel syndrome can also be to blame. Ultimately, in the United States, the most likely cause of this pain is being overweight. With more than 60% of the nation obese or morbidly obese, foot pain related to excessive weight is most likely. Dietary changes are most likely to cause long-term relief for bone spurs and plantar fasciitis.

Symptoms


Pain and discomfort associated with heel spurs does not occur from the spur itself. The bone growth itself has no feeling. However, as you move, this growth digs into sensitive nerves and tissue along the heel of the foot, resulting in severe pain. Pain can also be generated when pushing off with the toes while walking. Swelling along the heel is also common.


Diagnosis


Because the diagnosis of heel spurs can be confused with tarsal tunnel syndrome (as described earlier), most surgeons advocate performing a tarsal tunnel release (or at least a partial tarsal tunnel release) along with the plantar fascia release. This surgery is about 80percent successful in relieving pain in the small group of patients who do not improve with conservative treatments.


Non Surgical Treatment


Heel spurs can be treated by wearing orthotic insoles inside the shoe. Orthotics are designed to correct incorrect gait, in particular over-pronation (rolling in of the foot and collapsing of the arches). Over-pronation is a very common foot condition, affecting at least half of the population. It is a major contributing cause of heel spurs. Orthotics are very effective in that the device corrects the foot to its natural position. By supporting the arches properly and preventing excess rolling in of the foot, the plantar fascia is placed under much less strain and stress compared to an unsupported foot. Less strain on the ligament means less pulling away from the heel bone, allowing the inflammation to heal faster. In addition to orthotic treatment, most podiatrists and physiotherapists recommend a series of exercises to help make the ligaments in the feet and legs longer and more flexible. In turn this will help reduce strain on the plantar fascia.


Surgical Treatment


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.

Overview


Patients and doctors often confuse the terms heel spur and plantar fasciitis. While these two diagnoses are related, they are not the same. Plantar fasciitis refers to the inflammation of the plantar fascia--the tissue that forms the arch of the foot. A heel spur is a hook of bone that can form on the heel bone (calcaneus) and is associated with plantar fasciitis. About 70 percent of patients with plantar fasciitis have a heel spur that can be seen on an X-ray. However, many patients without symptoms of pain can have a heel spur. The exact relationship between plantar fasciitis and heel spurs is not entirely understood. Heel spurs are common in patients who have a history of foot pain caused by plantar fasciitis.


Causes


A heel spur usually develops as a result of wear and tear over time, which leads to the degeneration of connective tissue called fascia. Standing for prolonged periods and wearing shoes that do not provide the right type of arch support can also lead to connective tissue damage in the heel. The body attempts to repair the damaged tissue by delivering calcium to the affected region, but sometimes too much calcium begins to accumulate and this results in painful plantar fasciitis.

Symptoms


The Heel Spur itself is not thought to be painful. Patients who experience pain with Plantar Fasciitis are suffering from inflammation and irritation of the plantar fascia. This the primary cause of pain and not the Heel Spur. Heel Spurs form in some patients who have plantar fasciitis, and tend to occur in patients who have had the problem for a prolonged period of time. While about 70 % of patients with plantar fasciitis have a heel spur, X-rays also show about 50 % of patients with no symptoms of plantar fasciitis also have a heel spur.


Diagnosis


A thorough history and physical exam 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.


Surgical Treatment


When chronic heel pain fails to respond to conservative treatment, surgical treatment may be necessary. Heel surgery can provide pain relief and restore mobility. The type of procedure used is based on examination and usually consists of releasing the excessive tightness of the plantar fascia, called a plantar fascia release. The procedure may also include removal of heel spurs.


Prevention


You can help prevent heel spur symptoms from returning by wearing the proper shoes. Customized orthotics and insoles can help relieve pressure. It is important to perform your exercises to help keep your foot stretched and relaxed.
