Plantar fasciitis is characterized by stiffness and inflammation of the main fascia (fibrous connective [ligament-like] tissue) on the bottom of the foot. It is occasionally associated with a bone
spur on the heel. Occasionally there may be a partial or complete tear of the fascia of the bottom of the foot. Bone spurs themselves usually do not cause symptoms.
When the foot moves, the plantar fascia stretches and contracts. Plantar fasciitis is caused by the repetitive overstretching of the plantar fascia. If the tension on the plantar fascia is too great,
this overstretching causes small tears in the plantar fascia. This in turn causes the plantar fascia to become inflamed and painful. Factors that contribute to the development of plantar fasciitis
include having very high arches or flat feet, gender, while anyone can develop plantar fasciitis, it tends to occur more commonly in women, exercises such as running, walking and dancing,
particularly if the calf muscles are tight. Activities or occupations that involve walking or standing for long periods of time, particularly on hard surfaces, wearing high heeled shoes or shoes that
do not offer adequate arch support and cushioning, being overweight, additional weight increases the tension on the plantar fascia, poor biomechanics, extra tension is placed on the plantar fascia if
weight is not spread evenly when standing, walking or running. Some cases of plantar fasciitis may be linked to underlying diseases that cause arthritis, such as ankylosing spondylitis.
Plantar fasciitis is usually found in one foot. While bilateral plantar fasciitis is not unheard of, this condition is more the result of a systemic arthritic condition that is extremely rare in an
athletic population. There is a greater incidence of plantar fasciitis in males than females (Ambrosius 1992). While no direct cause could be found it could be argued that males are generally heavier
which, when combined with the greater speeds, increased ground contact forces, and less flexibility, may explain the greater injury predisposition. The most notable characteristic of plantar
fasciitis is pain upon rising, particularly the first step out of bed. This morning pain can be located with pinpoint accuracy at the bony landmark on the anterior medial tubercle of the calcaneus.
The pain may be severe enough to prevent the athlete from walking barefooted in a normal heel-toe gait. Other less common presentations include referred pain to the subtalar joint, the forefoot, the
arch of the foot or the achilles tendon (Brantingham 1992). After several minutes of walking the pain usually subsides only to re turn with the vigorous activity of the day's training session. The
problem should be obvious to the coach as the athlete will exhibit altered gait and/ or an abnormal stride pattern, and may complain of foot pain during running/jumping activities. Consistent with
plantar fascia problems the athlete will have a shortened gastroc complex. This can be evidenced by poor dorsiflexion (lifting the forefoot off the ground) or inability to perform the "flying frog"
position. In the flying frog the athlete goes into a full squat position and maintains balance and full ground contact with the sole of the foot. Elevation of the heel signifies a tight gastroc
complex. This test can be done with the training shoes on.
Your doctor will check your feet and watch you stand and walk. He or she will also ask questions about your past health, including what illnesses or injuries you have had. Your symptoms, such as
where the pain is and what time of day your foot hurts most. How active you are and what types of physical activity you do. Your doctor may take an X-ray of your foot if he or she suspects a problem
with the bones of your foot, such as a stress fracture.
Non Surgical Treatment
Your GP or podiatrist may advise you to change your footwear. You should avoid wearing flat-soled shoes, because they will not provide your heel with support and could make your heel pain worse.
Ideally, you should wear shoes that cushion your heels and provide a good level of support to the arches of your feet. For women wearing high heels, and for men wearing heeled boots or brogues, can
provide short- to medium-term pain relief, as they help reduce pressure on the heels. However, these types of shoes may not be suitable in the long term, because they can lead to further episodes of
heel pain. Your GP or podiatrist can advise on footwear. Orthoses are insoles that fit inside your shoe to support your foot and help your heel recover. You can buy orthoses off-the-shelf from sports
shops and larger pharmacies. Alternatively, your podiatrist should be able to recommend a supplier. If your pain does not respond to treatment and keeps recurring, or if you have an abnormal foot
shape or structure, custom-made orthoses are available. These are specifically made to fit the shape of your feet. However, there is currently no evidence to suggest that custom-made orthoses are
more effective than those bought off-the-shelf. An alternative to using orthoses is to have your heel strapped with sports strapping (zinc oxide) tape, which helps relieve pressure on your heel. Your
GP or podiatrist can teach you how to apply the tape yourself. In some cases, night splints can also be useful. Most people sleep with their toes pointing down, which means tissue inside the heel is
squeezed together. Night splints, which look like boots, are designed to keep your toes and feet pointing up while you are asleep. This will stretch both your Achilles tendon and your plantar fascia,
which should help speed up your recovery time. Night splints are usually only available from specialist shops and online retailers. Again, your podiatrist should be able to recommend a supplier. If
treatment hasn't helped relieve your painful symptoms, your GP may recommend corticosteroid injections. Corticosteroids are a type of medication that have a powerful anti-inflammatory effect. They
have to be used sparingly because overuse can cause serious side effects, such as weight gain and high blood pressure (hypertension). As a result, it is usually recommended that no more than three
corticosteroid injections are given within a year in any part of the body. Before having a corticosteroid injection, a local anaesthetic may be used to numb your foot so you don't feel any
Surgery is rarely needed in the treatment of plantar fasciitis. The vast majority of patients diagnosed with plantar fasciitis will recover given ample time. With some basic treatment steps, well
over 90% of patients will achieve full recovery from symptoms of plantar fasciitis within one year of the onset of treatment. Simple treatments include anti-inflammatory medication, shoe inserts, and
stretching exercises. In patients where a good effort with these treatments fails to provide adequate relief, some more aggressive treatments may be attempted. These include cortisone injections or
extracorporeal shock wave treatments.
Stretching your plantar fasciitis is something you can do at home to relieve pain and speed healing. Ice massage performed three to four times per day in 15 to 20 minute intervals is also something
you can do to reduce inflammation and pain. Placing arch supports in your shoes absorbs shock and takes pressure off the plantar fascia.
