The Plantar Fascia is a strong ligament-like structure under the arch of the foot that runs from the heel bone to the ball of the foot. If we could see it in isolation it has a triangular shape when
looked at from underneath but has a curved shape when looked at from the side - much like a sail boatâs sail billowing in the wind. The most functional piece is from the front-bottom-inside area of
the heel bone (calcaneous) to the joint of the big toe (hallux) and this is where the majority of stress of walking (and running and jumping) is taken by the fascia. How your plantar fascia reacts to
and recovers from this stress is what determines the extent and nature of your plantar fasciitis.
The most common cause of plantar fasciitis relates to faulty structure of the foot. For example, people who have problems with their arches, either overly flat feet or high-arched feet, are more
prone to developing plantar fasciitis. Wearing non-supportive footwear on hard, flat surfaces puts abnormal strain on the plantar fascia and can also lead to plantar fasciitis. This is particularly
evident when oneâs job requires long hours on the feet. Obesity may also contribute to plantar fasciitis.
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.
During the physical exam, your doctor checks for points of tenderness in your foot. The location of your pain can help determine its cause. Usually no tests are necessary. The diagnosis is made based
on the history and physical examination. Occasionally your doctor may suggest an X-ray or magnetic resonance imaging (MRI) to make sure your pain isn't being caused by another problem, such as a
stress fracture or a pinched nerve. Sometimes an X-ray shows a spur of bone projecting forward from the heel bone. In the past, these bone spurs were often blamed for heel pain and removed
surgically. But many people who have bone spurs on their heels have no heel pain.
Non Surgical Treatment
Night splints are treatment that can help stretch your calf and the arch of your foot. Night splints are a type of brace that holds your foot in a flexed position and lengthens the plantar fascia and
Achilles tendon overnight. This can prevent morning pain and stiffness. Special orthotics, or arch supports, for your shoes may help alleviate some of the pain by distributing pressure, and can
prevent further damage to the plantar fascia. A boot cast may be used to immobilize your foot and reduce strain while the plantar fascia heals. A boot cast looks like a ski boot and can be removed
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.
An important part of prevention is to perform a gait analysis to determine any biomechanical problems with the foot which may be causing the injury. This can be corrected with orthotic inserts into
the shoes. If symptoms do not resolve then surgery is an option, however this is more common for patients with a rigid high arch where the plantar fascia has shortened.
