Do I Have Calcaneal Spur

Heel Spur


Overview


A calcaneal spur (or heel spur) is a small osteophyte (bone spur) located on the calcaneus (heel bone). Calcaneal spurs are typically detected by a radiological examination (X-ray). When a foot bone is exposed to constant stress, calcium deposits build up on the bottom of the heel bone. Generally, this has no effect on a person's daily life. However, repeated damage can cause these deposits to pile up on each other,causing a spur-shaped deformity, called a calcaneal (or heel) spur. Obese people, flatfooted people, and women who constantly wear high-heeled shoes are most susceptible to heel spurs. An inferior calcaneal spur is located on the inferior aspect of the calcaneus and is typically a response to plantar fasciitis over a period, but may also be associated with ankylosing spondylitis (typically in children). A posterior calcaneal spur develops on the back of the heel at the insertion of the Achilles tendon. An inferior calcaneal spur consists of a calcification of the calcaneus, which lies superior to the plantar fascia at the insertion of the plantar fascia. A posterior calcaneal spur is often large and palpable through the skin and may need to be removed as part of the treatment of insertional Achilles tendonitis. These are also generally visible to the naked eye.


Causes


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.

Symptoms


You'll typically first notice early heel spur pain under your heel in the morning or after resting. Your heel pain will be worse with the first steps and improves with activity as it warms up. When you palpate the tender area you may feel a tender bony lump. As your plantar fasciitis deteriorates and your heel spur grows, the pain will be present more often.


Diagnosis


A heel spur is often seen on X-ray as a bony protrusion, which can vary in size. However, because a Heel Spur only indicates increased load on the plantar fascia, and not pain, an ultra sound may be required to assess other actual cause of the heel pain such and may include checking to see if the plantar fascia is inflamed or degenerated.


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


Approximately 2% of people with painful heel spurs need surgery, meaning that 98 out of 100 people do well with the non-surgical treatments previously described. However, these treatments can sometimes be rather long and drawn out, and may become considerably expensive. Surgery should be considered when conservative treatment is unable to control and prevent the pain. If the pain goes away for a while, and continues to come back off and on, despite conservative treatments, surgery should be considered. If the pain really never goes away, but reaches a plateau, beyond which it does not improve despite conservative treatments, surgery should be considered. If the pain requires three or more injections of "cortisone" into the heel within a twelve month period, surgery should be considered.
