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.
Heel spurs can form as a result of repeated strain placed on foot muscles and ligaments as well as from abnormally stretching the band of tissue connecting the heel and ball of the foot. Repeated injury to the membrane that lines the heel bone can also cause problems as can repeated tight pressure on the back of the heel. The causes can range from excessive walking (especially if unaccustomed to walking), running or jumping to improperly fitted or worn-out shoes. Runners, volleyball players, and tennis players, people who do step aerobics or stair climbing for exercise, those with flat feet, pregnant women, the obese and diabetics and those who wear tight-fitting shoes with a high heel are all prone to developing spurs (and plantar fasciitis) more readily.
Heel spurs can be quite painful, but can just as likely occur with no symptoms at all. Plantar fasciitis is a contributing condition to heel spurs. The cause of the pain is not the heel spur itself but the soft-tissue injury associated with it. The feeling has been described as a knife or pin sticking into the bottom of your feet when you first stand up after sitting or laying down for a long period of time - a pain that later turns into a dull ache.
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
Treatment of heel spurs is the same as treatment of plantar fasciitis. Because these problems are related, the treatment is the same. The first step in the treatment of a heel spur is short-term rest and inflammation control. Here are the steps patients should take in order to cure the symptoms of plantar fasciitis and heel spurs. Avoiding the activity that caused the symptoms is the first step in treatment. For example, take a few day off jogging or prolonged standing/walking. Just resting usually helps to eliminate the most severe pain, and will allow the inflammation to begin to cool down. Icing will help to diminish some of the symptoms and control the heel pain. Icing is especially helpful after a sudden flare up of symptoms. Exercises and stretches are designed to relax the tissues that surround the heel bone. Some simple exercises, performed in the morning and evening, often help patients feel better quickly. Many patients will work with a physical therapist, or you can try some simple activities on your own. If you need some help, meet with a therapist for a few sessions to learn a program you can continue on your own.
Almost 90% of the people suffering from heel spur get better with nonsurgical treatments. However, if the conservative treatments do not help you and you still have pain even after 9 to 12 months, your doctor may advise surgery for treating heel spur. The surgery helps in reducing the pain and improving your mobility. Some of the surgical techniques used by doctors are release of the plantar fascia. Removal of a spur. Before the surgery, the doctor will go for some pre-surgical tests and exams. After the operation, you will need to follow some specific recommendations which may include elevation of the foot, waiting time only after which you can put weight on the foot etc.
To prevent this condition, wearing shoes with proper arches and support is very important. Proper stretching is always a necessity, especially when there is an increase in activities or a change in running technique. It is not recommended to attempt working through the pain, as this can change a mild case of heel spurs and plantar fascitis into a long lasting and painful episode of this condition.
