The plantar fascia is made up of 3 distinct parts: the medial, central, and lateral bands. The central plantar fascia is the thickest and strongest section, and this segment is also the most likely
to be involved with plantar fasciitis. In normal circumstances, the plantar fascia acts like a windlass mechanism to provide tension and support through the arch. It functions as a tension bridge in
the foot, providing both static support and dynamic shock absorption.
Plantar fasciitis is usually not the result of a single event but more commonly the result of a history of repetitive micro trauma combined with a biomechanical deficiency of the foot. Arthritic
changes and metabolic factors may also playa part in this injury but are unlikely in a young athletic population. The final cause of plantar fasciitis is "training errors." In all likelihood the
injury is the result of a combination of biomechanical deficiencies and training errors. Training errors are responsible for up to 60% of all athletic injuries (Ambrosius 1992). The most frequent
training error seen with plantar fasciitis is a rapid increase in volume (miles or time run) or intensity (pace and/or decreased recovery). Training on improper surfaces, a highly crowned road,
excessive track work in spiked shoes, plyometrics on hard runways or steep hill running, can compromise the plantar fascia past elastic limits. A final training error seen in athletics is with a
rapid return to some preconceived fitness level. Remembering what one did "last season" while forgetting the necessity of preparatory work is part of the recipe for injury. Metabolic and arthritic
changes are a less likely cause of plantar fasciitis among athletes. Bilateral foot pain may indicate a metabolic or systemic problem. The definitive diagnosis in this case is done by a professional
with blood tests and possibly x-rays.
The pain associated with plantar fasciitis is typically gradual in onset and is usually located over the inner or medial aspect of the heel. Occasionally, the pain will be sudden in onset, occurring
after missing a step or after jumping from a height. The pain is commonly most severe upon arising from bed in the morning, or after periods of inactivity during the day. Thus, it causes what is
known as "first-step pain." The degree of discomfort can sometimes lessen with activity during the course of the day or after "warming-up", but can become worse if prolonged or vigorous activity is
undertaken. The pain is also often noted to be more severe in bare feet or in shoes with minimal or no padding at the sole.
Plantar fasciitis is one of many conditions causing "heel pain". Some other possible causes include nerve compression either in the foot or in the back, stress fracture of the calcaneus, and loss of
the fatty tissue pad under the heel. Plantar fasciitis can be distinguished from these and other conditions based on a history and examination done by a physician. It should be noted that heel spurs
are often inappropriately thought to be the sole cause of heel pain. In fact, heel spurs are common and are nothing more than the bone's response to traction or pulling-type forces from the plantar
fascia and other muscles in the foot where they attach to the heel bone. They are commonly present in patients without pain, and frequently absent from those who have pain. It is the rare patient who
has a truly enlarged and problematic spur requiring surgery.
Non Surgical Treatment
More than 90% of patients with plantar fasciitis will improve within 10 months of starting simple treatment methods. Rest. Decreasing or even stopping the activities that make the pain worse is the
first step in reducing the pain. You may need to stop athletic activities where your feet pound on hard surfaces (for example, running or step aerobics). Ice. Rolling your foot over a cold water
bottle or ice for 20 minutes is effective. This can be done 3 to 4 times a day. Nonsteroidal anti-inflammatory medication. Drugs such as ibuprofen or naproxen reduce pain and inflammation. Using the
medication for more than 1 month should be reviewed with your primary care doctor. Exercise. Plantar fasciitis is aggravated by tight muscles in your feet and calves. Stretching your calves and
plantar fascia is the most effective way to relieve the pain that comes with this condition. Cortisone injections. Cortisone, a type of steroid, is a powerful anti-inflammatory medication. It can be
injected into the plantar fascia to reduce inflammation and pain. Your doctor may limit your injections. Multiple steroid injections can cause the plantar fascia to rupture (tear), which can lead to
a flat foot and chronic pain. Soft heel pads can provide extra support. Supportive shoes and orthotics. Shoes with thick soles and extra cushioning can reduce pain with standing and walking. As you
step and your heel strikes the ground, a significant amount of tension is placed on the fascia, which causes microtrauma (tiny tears in the tissue). A cushioned shoe or insert reduces this tension
and the microtrauma that occurs with every step. Soft silicone heel pads are inexpensive and work by elevating and cushioning your heel. Pre-made or custom orthotics (shoe inserts) are also helpful.
Night splints. Most people sleep with their feet pointed down. This relaxes the plantar fascia and is one of the reasons for morning heel pain. A night splint stretches the plantar fascia while you
sleep. Although it can be difficult to sleep with, a night splint is very effective and does not have to be used once the pain is gone. Physical therapy. Your doctor may suggest that you work with a
physical therapist on an exercise program that focuses on stretching your calf muscles and plantar fascia. In addition to exercises like the ones mentioned above, a physical therapy program may
involve specialized ice treatments, massage, and medication to decrease inflammation around the plantar fascia. Extracorporeal shockwave therapy (ESWT). During this procedure, high-energy shockwave
impulses stimulate the healing process in damaged plantar fascia tissue. ESWT has not shown consistent results and, therefore, is not commonly performed. ESWT is noninvasive-it does not require a
surgical incision. Because of the minimal risk involved, ESWT is sometimes tried before surgery is considered.
More invasive procedures to treat plantar fasciitis are usually sought only after other treatment has failed to produce favorable results. Corticosteroid injections deliver medicine into the injured
fascia to reduce pain. However, this treatment may weaken the plantar fascia and result in further damage. In addition, extracorporeal shock wave therapy (ESWT) is a treatment where sound waves are
sent through the damaged tissue in order to stimulate the damaged tissue and encourage healing. This method is relatively new in treating plantar fasciitis and your doctor will be able to tell you if
it is the right method for you. Lastly, surgery is the last option for those suffering from chronic or severe plantar fasciitis.
Being overweight can place excess pressure and strain on your feet, particularly on your heels. Losing weight, and maintaining a healthy weight by combining regular exercise with a healthy, balanced
diet, can be beneficial for your feet. Wearing appropriate footwear is also important. Ideally, you should wear shoes with a low to moderate heel that supports and cushions your arches and heels.
Avoid wearing shoes with no heels.
