What Is Plantar Fasciitis

Overview

Plantar fasciosis is pain at the site of the attachment of the plantar fascia and the calcaneus (calcaneal enthesopathy), with or without accompanying pain along the medial band of the plantar fascia. Diagnosis is mainly clinical. Treatment involves calf muscle and plantar soft-tissue foot-stretching exercises, night splints, orthotics, and shoes with appropriate heel elevation. Syndromes of pain in the plantar fascia have been called plantar fasciitis; however, because there is usually no inflammation, plantar fasciosis is more correct. Other terms used include calcaneal enthesopathy pain or calcaneal spur syndrome; however, there may be no bone spurs on the calcaneus. Plantar fasciosis may involve acute or chronic stretching, tearing, and degeneration of the fascia at its attachment site.




Causes

There are several possible causes of plantar fasciitis, including wearing high heels, gaining weight, increased walking, standing, or stair-climbing. If you wear high-heeled shoes, including western-style boots, for long periods of time, the tough, tendonlike tissue of the bottom of your foot can become shorter. This layer of tissue is called fascia. Pain occurs when you stretch fascia that has shortened. This painful stretching might happen, for example, when you walk barefoot after getting out of bed in the morning. If you gain weight, you might be more likely to have plantar fasciitis, especially if you walk a lot or stand in shoes with poor heel cushioning. Normally there is a pad of fatty tissue under your heel bone. Weight gain might break down this fat pad and cause heel pain. Runners may get plantar fasciitis when they change their workout and increase their mileage or frequency of workouts. It can also occur with a change in exercise surface or terrain, or if your shoes are worn out and don't provide enough cushion for your heels. If the arches of your foot are abnormally high or low, you are more likely to develop plantar fasciitis than if your arches are normal.




Symptoms

Pain is the main symptom. This can be anywhere on the underside of your heel. However, commonly, one spot is found as the main source of pain. This is often about 4 cm forward from your heel, and may be tender to touch. The pain is often worst when you take your first steps on getting up in the morning, or after long periods of rest where no weight is placed on your foot. Gentle exercise may ease things a little as the day goes by, but a long walk or being on your feet for a long time often makes the pain worse. Resting your foot usually eases the pain. Sudden stretching of the sole of your foot may make the pain worse, for example, walking up stairs or on tiptoes. You may limp because of pain. Some people have plantar fasciitis in both feet at the same time.




Diagnosis

Your doctor may look at your feet and watch the way you stand, walk and exercise. He can also ask you questions about your health history, including illnesses and injuries that you had in your past. The symptoms you have such as the pain location or when does your foot hurts most. Your activity routine such as your job, exercise habits and physical activities preformed. Your doctor may decide to use an X-ray of your foot to detect bones problems. MRI or ultrasound can also be used as further investigation of the foot condition.




Non Surgical Treatment

Check your shoes to make sure they offer sufficient support and motion control. They should bend only at the ball of the foot, where your toes attach to the foot. This is very important. Avoid any shoe that bends in the center of the arch or behind the ball of the foot. It offers insufficient support and will stress your plantar fascia. The human foot was not designed to bend here and neither should a shoe be designed to do this. You may also strengthen the muscles in your arch by performing toe curls or "doming". Toe curls may be done by placing a towel on a kitchen floor and then curling your toes to pull the towel towards you. This exercise may also be done without the towel against the resistance of the floor. Plantar fasciitis is usually controlled with conservative treatment. Besides surgery and cortisone injections, physical therapy modalities such as electrical stimulation and ultrasound can be used. Often the foot will be taped to limit pronation. Following control of the pain and inflammation an orthotic (a custom made shoe insert) can be used to control over-pronation.






Surgical Treatment

The most dramatic therapy, used only in cases where pain is very severe, is surgery. The plantar fascia can be partially detached from the heel bone, but the arch of the foot is weakened and full function may be lost. Another surgery involves lengthening the calf muscle, a process called gastrocnemius recession. If you ignore the condition, you can develop chronic heel pain. This can change the way you walk and cause injury to your legs, knees, hips and back. Steroid injections and some other treatments can weaken the plantar fascia ligament and cause potential rupture of the ligament. Surgery carries the risks of bleeding, infection, and reactions to anesthesia. Plantar fascia detachment can also cause changes in your foot and nerve damage. Gastrocnemius resection can also cause nerve damage.




Prevention

The following steps will help prevent plantar fasciitis or help keep the condition from getting worse if you already have it. Take care of your feet. Wear shoes with good arch support and heel cushioning. If your work requires you to stand on hard surfaces, stand on a thick rubber mat to reduce stress on your feet. Do exercises to stretch the Achilles tendon at the back of the heel. This is especially important before sports, but it is helpful for non-athletes as well. Ask your doctor about recommendations for a stretching routine. Stay at a healthy weight for your height. Establish good exercise habits. Increase your exercise levels gradually, and wear supportive shoes. If you run, alternate running with other sports that will not cause heel pain. Put on supportive shoes as soon as you get out of bed. Going barefoot or wearing slippers puts stress on your feet. If you feel that work activities caused your heel pain, ask your human resources department for information about different ways of doing your job that will not make your heel pain worse. If you are involved in sports, you may want to consult a sports training specialist for training and conditioning programs to prevent plantar fasciitis from recurring.
