Overview


Heel spur is a thorn-like, bony protrusion of the heel bone, which can become inflamed through irritation, thus causing pain. A heel spur forms at the tendon attachments on the muscles of the heel bone as a result of micro-injuries to the tissue caused by overstraining. As part of the healing process for these micro-injuries, the body stores bone material in the tendon attachments as a repair mechanism. Heel spurs can develop over a very long period without causing major complaints. However, irritation of the area surrounding the ossified tendon attachment can cause inflammations. Left untreated, the inflammations can in turn lead to increased ossification and thus to permanent degradation with a risk of chronic manifestation. The normal rolling procedure that we all use when walking is then frequently no longer possible.


Causes


You are more likely to develop plantar fasciitis and heel spurs if you are Active. Sports that place excessive stress on the heel bone and attached tissue, especially if you have tight calf muscles or a stiff ankle from a previous ankle sprain, which limits ankle movement eg. running, ballet dancing and aerobics. Overweight. Carrying around extra weight increases the strain and stress on your plantar fascia. Pregnant. The weight gain and swelling associated with pregnancy can cause ligaments to become more relaxed, which can lead to mechanical problems and inflammation. On your feet. Having a job that requires a lot of walking or standing on hard surfaces ie factory workers, teachers and waitresses. Flat Feet or High Foot Arches. Changes in the arch of your foot changes the shock absorption ability and can stretch and strain the plantar fascia, which then has to absorb the additional force. Middle-Aged or Older. With ageing the arch of your foot may begin to sag - putting extra stress on the plantar fascia. Wearing shoes with poor support. Weak Foot Arch Muscles. Muscle fatigue allows your plantar fascia to overstress and cause injury. Arthritis. Some types of arthritis can cause inflammation in the tendons in the bottom of your foot, which may lead to plantar fasciitis. Diabetes. Although doctors don't know why, plantar fasciitis occurs more often in people with diabetes.





Symptoms


Heel spurs often cause no symptoms. But heel spurs can be associated with intermittent or chronic pain, especially while walking, jogging, or running, if inflammation develops at the point of the spur formation. In general, the cause of the pain is not the heel spur itself but the soft-tissue injury associated with it. Many people describe the pain of heel spurs and plantar fasciitis as a knife or pin sticking into the bottom of their feet when they first stand up in the morning, a pain that later turns into a dull ache. They often complain that the sharp pain returns after they stand up after sitting for a prolonged period of time.


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


Conventional treatment for heel spurs typically includes rest, stretching exercises, icing and anti-inflammatory medications. Many people find it difficult to go through the day without some sort of routine activity or exercise, and this prolongs the heel spur and forces people to rely on anti-inflammatory medications for a longer period of time. This can be detrimental due to the many side effects of these medications, including gastrointestinal problems like leaky gut, bleeding and ulcer symptoms.


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


In 2002, researchers attempted to compare the effects of various running techniques on pronation and resulting injuries like stress fractures and heel spurs. They suggested that it is possible to teach runners to stride in such a way as to minimize impact forces. One way is to lower running speed. Another is to take longer rest periods following a run.
