Plantar fasciitis is a condition characterised by damage and inflammation to the plantar fascia (i.e. the connective tissue on the sole of the foot forming the inner arch. This usually occurs at the
attachment of the plantar fascia to the heel bone. Plantar fasciitis is the most common cause of heel pain seen in clinical practice. During walking or running, tension is placed through the plantar
fascia. When this tension is excessive (often due to poor foot biomechanics such as flat feet or if it is too repetitive or forceful, damage to the plantar fascia can occur. Plantar fasciitis is a
condition where there is damage to the plantar fascia with subsequent inflammation and degeneration. This may occur traumatically due to a high force going through the plantar fascia beyond what it
can withstand or, more commonly, due to gradual wear and tear associated with overuse. Occasionally, a heel spur may develop in association with plantar fasciitis.
Training on improper, hard and/or irregular surfaces as well as excessive track work in spiked shoes, or steep hill running, can stress the plantar fascia past its limits of elasticity, leading to
injury. Finally, failure in the early season to warm up gradually gives the athlete insufficient time for the structures of the foot to re-acclimate and return to a proper fitness level for intensive
exercise. Such unprepared and repeated trauma causes microscopic tearing, which may only be detected once full-blown plantar fasciitis and accompanying pain and debilitation have resulted. If the
level of damage to the plantar fascia is significant, an inflammatory reaction of the heel bone can produce spike-like projections of new bone, known as heel spurs. Indeed, plantar fasciitis has
occasionally been refereed to as heel spur syndrome, though such spurs are not the cause of the initial pain but are instead a further symptom of the problem. While such spurs are sometimes painless,
in other cases they cause pain or disability in the athlete, and surgical intervention to remove them may be required. A dull, intermittent pain in the heel is typical, sometimes progressing to a
sharp, sustained discomfort. Commonly, pain is worse in the morning or after sitting, later decreasing as the patient begins walking, though standing or walking for long periods usually brings
renewal of the pain.
Plantar fascia usually causes pain and stiffness on the bottom of your heel although some people have heel spurs and suffer no symptoms at all. Occasionally, heel pain is also associated with other
medical disorders such as arthritis (inflammation of the joint), bursitis (inflammation of the tissues around the joint). Those who have symptoms may experience âFirst stepâ pain (stone bruise
sensation) after getting out of bed or sitting for a period of time. Pain after driving. Pain on the bottom of your heel. Deep aching pain. Pain can be worse when barefoot.
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
Management options are usually conservative. Local injection of steroids, local anaesthetic may be useful to manage symptoms. Ultrasound-guided steroid injection has been shown to be effective in
short-term (four-week) pain relief and reduced thickness of the plantar fascia at three months. A posterior tibial nerve block can be performed prior for a less painful plantar fascia injection.
Specific plantar fascia stretching exercises performed daily have been shown to reduce short-term (8 weeks) and long-term (two years) pain. Other supportive measures include weight reduction in obese
patients, rest, non-steroidal anti-inflammatory drugs (NSAIDs) and reduction of weight-bearing pressure (soft rubber heel pad, molded orthosis, or heel cup or soft-soled shoes).
Most practitioners agree that treatment for plantar fasciitis is a slow process. Most cases resolve within a year. If these more conservative measures don't provide relief after this time, your
doctor may suggest other treatment. In such cases, or if your heel pain is truly debilitating and interfering with normal activity, your doctor may discuss surgical options with you. The most common
surgery for plantar fasciitis is called a plantar fascia release and involves releasing a portion of the plantar fascia from the heel bone. A plantar fascia release can be performed through a regular
incision or as endoscopic surgery, where a tiny incision allows a miniature scope to be inserted and surgery to be performed. About one in 20 patients with plantar fasciitis will need surgery. As
with any surgery, there is still some chance that you will continue to have pain afterwards.
Exercises designed to stretch both your calf muscles and your plantar fascia (the band of tissue that runs under the sole of your foot) should help relieve pain and improve flexibility in the
affected foot. A number of stretching exercises are described below. It's usually recommended that you do the exercises on both legs, even if only one of your heels is affected by pain. This will
improve your balance and stability, and help relieve heel pain. Towel stretches. Keep a long towel beside your bed. Before you get out of bed in the morning, loop the towel around your foot and use
it to pull your toes towards your body, while keeping your knee straight. Repeat three times on each foot. Wall stretches. Place both hands on a wall at shoulder height, with one of your feet in
front of the other. The front foot should be about 30cm (12 inches) away from the wall. With your front knee bent and your back leg straight, lean towards the wall until you feel a tightening in the
calf muscles of your back leg. Then relax. Repeat this exercise 10 times before switching legs and repeating the cycle. You should practise wall stretches twice a day. Stair stretches. Stand on a
step of your stairs facing upstairs, using your banister for support. Your feet should be slightly apart, with your heels hanging off the back of the step. Lower your heels until you feel a
tightening in your calves. Hold this position for about 40 seconds, before raising your heels back to the starting position. Repeat this procedure six times, at least twice a day. Chair stretches.
Sit on a chair, with your knees bent at right angles. Turn your feet sideways so your heels are touching and your toes are pointing in opposite directions. Lift the toes of the affected foot upwards,
while keeping the heel firmly on the floor. You should feel your calf muscles and Achilles tendon (the band of tissue that connects your heel bone to your calf muscle) tighten. Hold this position for
several seconds and then relax. Repeat this procedure 10 times, five to six times a day. Dynamic stretches. While seated, roll the arch of your foot (the curved bottom part of the foot between your
toes and heel) over a round object, such as a rolling pin, tennis ball or drinks can. Some people find that using a chilled can from their fridge has the added benefit of helping to relieve pain.
Move your foot and ankle in all directions over the object for several minutes. Repeat the exercise twice a day.
