Plantar fasciitis is one of the most common explanations of heel pain. It is caused by inflammation to the thick band that connects the toes to the heel bone, called the plantar fascia, which runs
across the bottom of your foot. The condition is most commonly seen in runners, pregnant women, overweight people, and individuals who wear inadequately supporting shoes. Plantar fasciitis typically
affects people between the ages of 40 and 70. Plantar fasciitis commonly causes a stabbing pain in the heel of the foot, which is worse during the first few steps of the day after awakening. As you
continue to walk on the affected foot, the pain gradually lessens. Usually, only one foot is affected, but it can occur in both feet simultaneously. To diagnose plantar fasciitis, your doctor will
physically examine your foot.
Plantar fasciitis is the most common injury of the plantar fascia and is the most common cause of heel pain. Approximately 10% of people have plantar fasciitis at some point during their lifetime. It
is commonly associated with long periods of standing and is much more prevalent in individuals with excessive inward rolling of the foot, which is seen with flat feet. Among non-athletic populations,
plantar fasciitis is associated with obesity and lack of physical exercise.
Symptoms of plantar fasciitis can occur suddenly or gradually. When they occur suddenly, there is usually intense heel pain on taking the first morning steps, known as first-step pain. This heel pain
will often subside as you begin to walk around, but it may return in the late afternoon or evening. When symptoms occur gradually, a more long-lasting form of heel pain will cause you to shorten your
stride while running or walking. You also may shift your weight toward the front of the foot, away from the heel.
Plantar fasciitis is usually diagnosed by a health care provider after consideration of a personâs presenting history, risk factors, and clinical examination. Tenderness to palpation along the
inner aspect of the heel bone on the sole of the foot may be elicited during the physical examination. The foot may have limited dorsiflexion due to tightness of the calf muscles or the Achilles
tendon. Dorsiflexion of the foot may elicit the pain due to stretching of the plantar fascia with this motion. Diagnostic imaging studies are not usually needed to diagnose plantar fasciitis.
However, in certain cases a physician may decide imaging studies (such as X-rays, diagnostic ultrasound or MRI) are warranted to rule out other serious causes of foot pain. Bilateral heel pain or
heel pain in the context of a systemic illness may indicate a need for a more in-depth diagnostic investigation. Lateral view x-rays of the ankle are the recommended first-line imaging modality to
assess for other causes of heel pain such as stress fractures or bone spur development. Plantar fascia aponeurosis thickening at the heel greater than 5 millimeters as demonstrated by ultrasound is
consistent with a diagnosis of plantar fasciitis. An incidental finding associated with this condition is a heel spur, a small bony calcification on the calcaneus (heel bone), which can be found in
up to 50% of those with plantar fasciitis. In such cases, it is the underlying plantar fasciitis that produces the heel pain, and not the spur itself. The condition is responsible for the creation of
the spur though the clinical significance of heel spurs in plantar fasciitis remains unclear.
Non Surgical Treatment
The key for the proper treatment of plantar fasciitis is determining what is causing the excessive stretching of the plantar fascia. When the cause is over-pronation (flat feet), an orthotic with
rearfoot posting and longitudinal arch support is an effective device to reduce the over-pronation and allow the condition to heal. If you have usually high arches, which can also lead to plantar
fasciitis, cushion the heel, absorb shock and wear proper footwear that will accommodate and comfort the foot. Other common treatments include stretching exercises, plantar fasciitis night splints,
wearing shoes that have a cushioned heel to absorb shock, and elevating the heel with the use of a heel cradle or heel cup. Heel cradles and heel cups provide extra comfort, cushion the heel, and
reduce the amount of shock and shear forces placed during everyday activities.
The majority of patients, about 90%, will respond to appropriate non-operative treatment measures over a period of 3-6 months. Surgery is a treatment option for patients with persistent symptoms, but
is NOT recommended unless a patient has failed a minimum of 6-9 months of appropriate non-operative treatment. There are a number of reasons why surgery is not immediately entertained including.
Non-operative treatment when performed appropriately has a high rate of success. Recovery from any foot surgery often takes longer than patients expect. Complications following this type of surgery
can and DO occur! The surgery often does not fully address the underlying reason why the condition occurred therefore the surgery may not be completely effective. Prior to surgical intervention, it
is important that the treating physician ensure that the correct diagnosis has been made. This seems self-evident, but there are other potential causes of heel pain. Surgical intervention may include
extracorporeal shock wave therapy or endoscopic or open partial plantar fasciectomy.
It is not always possible to prevent heel pain, but there are measures you can take to help avoid further episodes. Healthy weight. Being overweight can place excess pressure and strain on your feet,
particularly on your heels. This increases the risk of damaging your feet and heels. If you are overweight, losing weight and maintaining a healthy weight by combining regular exercise with a
healthy, balanced diet can be beneficial for your feet. You can calculate your body mass index (BMI) to find out whether you are a healthy weight for your height and build. To work out your BMI,
divide your weight in kilograms by your height in metres squared. A BMI of less than 18.5 means that you are underweight, 18.5-24.9 means that your weight is healthy, 25-29 means that you are
overweight, 30-40 means that you are obese, over 40 means that you are morbidly obese. You can also use the BMI healthy weight calculator to work out your BMI. Healthy feet. You should always wear
footwear that is appropriate for your environment and day-to-day activities. Wearing high heels when you go out in the evening is unlikely to be harmful. However, wearing them all week at work may
damage your feet, particularly if your job involves a lot of walking or standing. Ideally, you should wear shoes with laces and a low to moderate heel that supports and cushions your arches and
heels. Avoid wearing shoes with no heels.
