Plantar fasciitis is characterized by stiffness and inflammation of the main fascia (fibrous connective [ligament-like] tissue) on the bottom of the foot. It is occasionally associated with a bone spur on the heel. Occasionally there may be a partial or complete tear of the fascia of the bottom of the foot. Bone spurs themselves usually do not cause symptoms.
Plantar fasciitis is caused by small, repetitive trauma to the plantar fascia. This trauma can be due to activity that puts extra stress on the foot. Plantar fasciitis is most common in people who are 40-60 years old. Other risk factors that increase your chance of getting plantar fasciitis include physical exertion, especially in sports such as running, Volleyball, tennis, a sudden increase in exercise intensity or duration, physical activity that stresses the plantar fascia. People who spend a lot of time standing, a sudden increase in activities that affect the feet, obesity or weight gain, pre-existing foot problems, including an abnormally tight Achilles tendon, flat feet, or an ankle that rolls inward too much. Poor footwear. Heel spurs.
Patients experience intense sharp pain with the first few steps in the morning or following long periods of having no weight on the foot. The pain can also be aggravated by prolonged standing or sitting. The pain is usually experienced on the plantar surface of the foot at the anterior aspect of the heel where the plantar fascia ligament inserts into the calcaneus. It may radiate proximally in severe cases. Some patients may limp or prefer to walk on their toes. Alternative causes of heel pain include fat pad atrophy, plantar warts and foreign body.
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
Over-the-counter arch supports may be useful in patients with acute plantar fasciitis and mild pes planus. The support provided by over-the-counter arch supports is highly variable and depends on the material used to make the support. In general, patients should try to find the most dense material that is soft enough to be comfortable to walk on. Over-the-counter arch supports are especially useful in the treatment of adolescents whose rapid foot growth may require a new pair of arch supports once or more per season. Custom orthotics are usually made by taking a plaster cast or an impression of the individual’s foot and then constructing an insert specifically designed to control biomechanical risk factors such as pes planus, valgus heel alignment and discrepancies in leg length. For patients with plantar fasciitis, the most common prescription is for semi-rigid, three-quarters to full-length orthotics with longitudinal arch support. Two important characteristics for successful treatment of plantar fasciitis with orthotics are the need to control over-pronation and metatarsal head motion, especially of the first metatarsal head. In one study, orthotics were cited by 27 percent of patients as the best treatment. The main disadvantage of orthotics is the cost, which may range from $75 to $300 or more and which is frequently not covered by health insurance.
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.
