Plantar fasciitis is one of the most common conditions causing heel pain. The condition involves inflammation of the plantar fascia -- a tough, fibrous band of tissue that runs along the sole of the foot with attachments to the heel bone (calcaneus) proximally and to the base of the toes distally. The plantar fascia provides support to the arch of the foot and has an important role in normal foot mechanics during walking. Tension or stress in the plantar fascia increases when one places weight on the foot (such as with standing) and as one pushes off on the ball of the foot and toes -- motions which occur during normal walking or running. Inflammation and pain start in the fascia either as a result of an increase in activity level (as in initiating a walking or running program), or in association with the normal aging process. With aging, the fascia loses some of its normal elasticity or resilience and can become irritated with routine daily activities. Less commonly, plantar fasciitis can develop in association with general medical conditions such as lupus or rheumatoid arthritis.
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.
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 perform a physical exam to check for tenderness in your foot and the exact location of the pain to make sure that it’s not caused by a different foot problem. The doctor may ask you to flex your foot while he or she pushes on the plantar fascia to see if the pain gets worse as you flex and better as you point your toe. Mild redness or swelling will also be noted. Your doctor will evaluate the strength of your muscles and the health of your nerves by checking your reflexes, your muscle tone, your sense of touch and sight, your coordination, and your balance. X-rays or a magnetic resonance imaging (MRI) scan may be ordered to check that nothing else is causing your heel pain, such as a bone fracture.
Non Surgical Treatment
A steroid (cortisone) injection is sometimes tried if your pain remains bad despite the above 'conservative' measures. It may relieve the pain in some people for several weeks but does not always cure the problem. It is not always successful and may be sore to have done. Steroids work by reducing inflammation. Sometimes two or three injections are tried over a period of weeks if the first is not successful. Steroid injections do carry some risks, including (rarely) tearing (rupture) of the plantar fascia. Extracorporeal shock-wave therapy. In extracorporeal shock-wave therapy, a machine is used to deliver high-energy sound waves through your skin to the painful area on your foot. It is not known exactly how it works, but it is thought that it might stimulate healing of your plantar fascia. One or more sessions of treatment may be needed. This procedure appears to be safe but it is uncertain how well it works. This is mostly because of a lack of large, well-designed clinical trials. You should have a full discussion with your doctor about the potential benefits and risks. In studies, most people who have had extracorporeal shock-wave therapy have little in the way of problems. However, possible problems that can occur include pain during treatment, skin reddening, and swelling of your foot or bruising. Another theoretical problem could include the condition getting worse because of rupture of your plantar fascia or damage to the tissues in your foot. More research into extracorporeal shock-wave therapy for plantar fasciitis is needed. Other treatments. Various studies and trials have been carried out looking at other possible treatments for plantar fasciitis. Such treatments include injection with botulinum toxin and treatment of the plantar fascia with radiotherapy. These treatments may not be widely available. Some people benefit from wearing a special splint overnight to keep their Achilles tendon and plantar fascia slightly stretched. The aim is to prevent the plantar fascia from tightening up overnight. In very difficult cases, sometimes a plaster cast or a removable walking brace is put on the lower leg. This provides rest, protection, cushioning and slight stretching of the plantar fascia and Achilles tendon. However, the evidence for the use of splint treatment of plantar fasciitis is limited.
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.
