Heel spurs are small lumps of excess bone that grow and stick out on the calcaneus, aka heel bone. They usually develop in response to friction, tightness, inflammation or injury when the body lays down extra layers of bone to try and protect itself. There are two areas where heel bone spurs tend to develop. At the back of the heel: these are usually due to conditions such as Achilles tendonitis, tight calf muscles or wearing tight footwear. These are known as posterior calcaneal spurs. Underneath the heel: these are usually due to conditions such as plantar fasciitis, muscle imbalance or altered foot biomechanics. These are known as inferior calcaneal spurs.
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.
The following symptoms are typical of heel spur. Stabbing pain when treading on the area affected. Dull, irregularly occurring pains in the heel area also without exerting pressure (e.g. in a reclining position) Pain when taking the first steps in the morning (after lying or sitting down for an extended period, especially in the morning) Occasional swelling in the ankle area. For the lower heel spur, extreme sensitivity at the tendon attachment (laterally in the lower heel area) For the upper heel spur, extreme pressure sensitivity of the Achilles tendon, primarily at approximately ankle height.
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
In many cases treatment is non-surgical and can relieve pain, but may take from three months to a year to fully recover. Performing stretching exercises to help relax the tissues in the heel as well as rest, icing, and over-the-counter anti-inflammatory or prescription medications can help ease symptoms. Customized orthotics or shoe inserts to position and cushion your heel can help.
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.
If you have not yet developed this condition, you can take steps to protect yourself from it. Most importantly, make it a rule to wear properly fitted footwear. Avoid shoes that have become worn down in the heel, and don't choose shoes that cause you to walk in an abnormal fashion. Maintaining a healthy weight will ensure that undue pressure isn't being put on the ligaments, tendons and bones of your feet. If your job requires a great deal of time on your feet, or if you exercise regularly, be sure to balance periods of activity with periods of rest for your feet.
