Plantar fasciitis is a painful inflammation of the plantar fascia, a fibrous band of tissue on the bottom of the foot that helps to support the arch. Plantar fasciitis occurs when this band of tissue is overloaded or overstretched. This causes small tears in the fibers of the fascia, especially where the fascia meets the heel bone. Plantar fasciitis is common in obese people and in pregnant women, perhaps because their extra body weight overloads the delicate plantar fascia. It is also more common in people with diabetes, although the exact reason for this is unknown. Plantar fasciitis also can be triggered by physical activities that overstretch the fascia, including sports (volleyball, running, tennis), other exercises (step aerobics, stair climbing) or household exertion (pushing furniture or a large appliance). In athletes, plantar fasciitis may follow intense training, especially in runners who push themselves too quickly to run longer distances. Worn or poorly constructed shoes can contribute to the problem if they do not provide enough arch support, heel cushion or sole flexibility.
You are at a greater risk for developing plantar fasciitis if you are overweight or obese. This is due to the increased pressure on your plantar fascia ligaments, especially if you have sudden weight gain. Women who are pregnant often experience bouts of plantar fasciitis, particularly during late pregnancy. If you are a long distance runner, you may be more likely to develop plantar fascia problems. You are also at risk if you have a very active job that involves being on your feet often, such as a factory worker or a restaurant server. Active men and women between the ages of 40 and 70 are at the highest risk for developing plantar fasciitis. It is also slightly more common in women than men. If you have foot problems, such as very high arches or very flat feet, you may develop plantar fasciitis. Tight Achilles tendons (the tendons attaching the calf muscles to the heels) may also result in plantar fascia pain. Simply wearing shoes with soft soles and poor arch support can also result in plantar fasciitis. Plantar fasciitis is not caused by heel spurs. A heel spur is a hook of bone that can form on the heel bone (calcaneus) of the foot. One out of every 10 people has a heel spur, but only one out of 20 people with heel spurs experience pain, according to OrthoInfo.
The classic sign of plantar fasciitis is that the worst pain occurs with the first few steps in the morning, but not every patient will have this symptom. Patients often notice pain at the beginning of activity that lessens or resolves as they warm up. The pain may also occur with prolonged standing and is sometimes accompanied by stiffness. In more severe cases, the pain will also worsen toward the end of the day.
Plantar fasciitis is usually diagnosed by your physiotherapist or sports doctor based on your symptoms, history and clinical examination. After confirming your plantar fasciitis they will investigate WHY you are likely to be predisposed to plantar fasciitis and develop a treatment plan to decrease your chance of future bouts. X-rays may show calcification within the plantar fascia or at its insertion into the calcaneus, which is known as a calcaneal or heel spur. Ultrasound scans and MRI are used to identify any plantar fasciitis tears, inflammation or calcification. Pathology tests (including screening for HLA B27 antigen) may identify spondyloarthritis, which can cause symptoms similar to plantar fasciitis.
Non Surgical Treatment
To alleviate the stress and pain on the fascia, the person can take shorter steps and avoid walking barefoot. Activities that involve foot impact, such as jogging, should be avoided. The most effective treatments include the use of in-shoe heel and arch cushioning with calf-stretching exercises and night splints that stretch the calf and plantar fascia while the patient sleeps. Prefabricated or custom-made foot orthotics may also alleviate fascial tension and symptoms. Other treatments may include activity modifications, NSAIDs, weight loss in obese patients, cold and ice massage therapy, and occasional corticosteroid injections. However, because corticosteroid injections can predispose to plantar fasciosis, many clinicians limit these injections. For recalcitrant cases, physical therapy, oral corticosteroids, and cast immobilization should be used before surgical intervention is considered. A newer form of treatment for recalcitrant types of plantar fasciosis is extracorporeal pulse activation therapy (EPAT), in which low-frequency pulse waves are delivered locally using a handheld applicator. The pulsed pressure wave is a safe, noninvasive technique that stimulates metabolism and enhances blood circulation, which helps regenerate damaged tissue and accelerate healing. EPAT is being used at major medical centers.
Surgery for plantar fasciitis can be very successful in the right patients. While there are potential complications, about 70-80% of patients will find relief after plantar fascia release surgery. This may not be perfect, but if plantar fasciitis has been slowing you down for a year or more, it may well be worth these potential risks of surgery. New surgical techniques allow surgery to release the plantar fascia to be performed through small incisions using a tiny camera to locate and cut the plantar fascia. This procedure is called an endoscopic plantar fascia release. Some surgeons are concerned that the endoscopic plantar fascia release procedure increases the risk of damage to the small nerves of the foot. While there is no definitive answer that this endoscopic plantar fascia release is better or worse than a traditional plantar fascia release, most surgeons still prefer the traditional approach.
While there are no sure ways to prevent plantar fasciitis, these prevention tips may be helpful. Keep your weight under reasonable control. Wear comfortable, supportive shoes. Use care when starting or intensifying exercise programmes.
