Plantar fasciitis is a painful condition causing heel pain and many people with the condition also have heel spurs. It affects the band of tissue (plantar fascia) that supports the middle part of the foot and runs along the sole of the foot from the heel to the ball of the foot. Usually the plantar fascia is strong and flexible but due to certain factors it can become irritated and inflamed where the plantar fascia joins the bone in the foot. Heel spurs occur when there’s constant pulling of the fascia at the heel bone. This leads to a bony growth or spur. The symptoms of plantar fasciitis are pain in the arch of the foot or heel. This pain is usually worse in the morning after rest when the plantar fascia tightens and shortens. Heel spurs cause a stabbing pain at the bottom or front of the heel bone.
Each time we take a step forward, all of our body weight first rests on the heel of one foot. As our weight moves forward, the entire foot begins to bear the body’s weight, and the foot flattens and this places a great deal of pressure and strain on the plantar fascia. There is very little elasticity to the plantar fascia, so as it stretches only slightly; it pulls on its attachment to the heel. If the foot is properly aligned this pull causes no problems. However, if the foot is “pronated” (the foot rolls outward at the ankle, causing a break down of the inner side of the shoe), the arch falls excessively, and this causes an abnormal stretching of the relatively inflexible plantar fascia, which in turn pulls abnormally hard on the heel. The same pathology occurs with “supination” (the rolling inward of the foot, causing a break down of the outer side of the shoe). Supinated feet are relatively in flexible; usually have a high arch, and a short or tight plantar fascia. Thus as weight is transferred from the heel to the remainder of the foot, the tight plantar fascia hardly stretches at all, and pulls with great force on its attachment to the heel.
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.
Most cases of plantar fasciitis are diagnosed by a health care provider who listens carefully to your description of symptoms. During an examination of your feet, your health care provider will have to press on the bottom of your feet, the area most likely to be painful in plantar fasciitis. Because the pain of plantar fasciitis has unique characteristics, pain upon rising, improvement after walking for several minutes, pain produced by pressure applied in a specific location on your foot but not with pressure in other areas, your health care provider will probably feel comfortable making the diagnosis based on your symptoms and a physical examination. Your health care provider may suggest that you have an X-ray of your foot to verify that there is no stress fracture causing your pain.
Non Surgical Treatment
In the early stages of plantar fasciitis resting the foot may ease the pain. Medication to reduce inflammation should help but should only be used short term. Strapping may temporarily reduce the pain. All of the above therapies are only temporary measures and the pain is likely to reoccur if the cause of the abnormal pressure which has triggered the plantar fasciitis has not been identified. In order to establish the cause of the plantar fasciitis a biomechanical assessment may be required.
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.
Do not walk barefoot on hard ground, particularly while on holiday. Many cases of heel pain occur when a person protects their feet for 50 weeks of the year and then suddenly walks barefoot while on holiday. Their feet are not accustomed to the extra pressure, which causes heel pain. If you do a physical activity, such as running or another form of exercise that places additional strain on your feet, you should replace your sports shoes regularly. Most experts recommend that sports shoes should be replaced after you have done about 500 miles in them.
