Overview
Plantar fasciitis refers to an inflammation of the plantar fascia, a thick, fibrous band running along the sole of the foot. Such inflammation results from direct injury to the plantar fascia, usually, repeated trauma to the tissue where the fascia attaches to the calcaneus or heel bone. The plantar fascia is critical in maintaining the foot?s complex arch system, also playing a role in balance and fine control of certain phases of the athlete?s gait. Injury to the plantar fascia is particularly painful and disabling for runners and can often prove stubbornly resistant to treatment. Rehabilitation is frequently a lengthy and frustrating process. For these reasons, care should be taken where possible to avoid such injury by means of preventative exercises and sensitivity to early warning signs. Causes A person with flat feet has greater load placed on the posterior tibial tendon which is the main tendon unit supporting up the arch of the foot. Throughout life, aging leads to decreased strength of muscles, tendons and ligaments. The blood supply diminishes to tendons with aging as arteries narrow. Heavier, obese patients have more weight on the arch and have greater narrowing of arteries due to atherosclerosis. In some people, the posterior tibial tendon finally gives out or tears. This is not a sudden event in most cases. Rather, it is a slow, gradual stretching followed by inflammation and degeneration of the tendon. Once the posterior tibial tendon stretches, the ligaments of the arch stretch and tear. The bones of the arch then move out of position with body weight pressing down from above. The foot rotates inward at the ankle in a movement called pronation. The arch appears collapsed, and the heel bone is tilted to the inside. The deformity can progress until the foot literally dislocates outward from under the ankle joint. Symptoms The primary symptom is pain or aching in the arch area. This can be accompanied by inflammation and tenderness. If the pain is caused by the plantar fascia, it is likely to be considerably more severe in the mornings due to the muscles being unused. If you notice that the twinges of pain you have are most commonly associated with or immediately after exercise, you might want to visit a good athletic shoe store to make sure you are wearing the right kind of shoe. Another cause of arch pain is plantar fasciitis. The plantar fascia is a tough tissue structure that holds the bottom part of the arch in place. The fascia often becomes inflamed and sore, usually as a result of repetitive motion (for example, very common in those who stand on their feet for work). The pain is often noticeable first thing in the morning and worse with activity. Diagnosis In more difficult cases of plantar fasciitis you should see your foot health professional for a thorough examination. They will find out why your arch or heel pain occurred in the first place and devise a treatment plan to relieve your pain and prevent it from reoccurring. They will evaluate your feet, walking pattern (gait), shoes, activities, exercise methods, and other relevant information and then devise your treatment plan. Non Surgical Treatment When you first begin to notice discomfort or pain in the area, you can treat yourself with rest, ice, compression, and elevation (RICE). Over-the-counter medications may also be used to reduce discomfort and pain. Rest will allow the tissues to heal themselves by preventing any further stress to the affected area. Ice should be applied no longer than 20 minutes. The ice may be put in a plastic bag or wrapped in a towel. Commercial ice packs are not recommended because they are usually too cold. Compression and elevation will help prevent any swelling of the affected tissues. There are two types of over-the-counter medication that may help with the pain and swelling of arch pain. Acetaminophen (Tylenol) will help with the pain, and a nonsteroidal anti-inflammatory such as aspirin, ibuprofen, or naproxen will help with the pain and battle the inflammatory response. Caution should be taken when using these drugs, and dosage should not exceed the labeled directions. Special care should be taken and a physician consulted if you have a history of stomach ulcers. Those who have chronic medical conditions or who are taking other medications should consult with their doctor regarding the most appropriate type of pain and/or anti-inflammatory medications. Commercial over-the-counter arch supports or orthotics may also help to ease arch pain. Surgical Treatment With flat feet, there is a tendon on the inside of the foot than can often become weakened, injured, split and/or ruptured. This tendon, is called the posterior tibial tendon, and is the main arch supporting tendon. Obviously damage to this tendon can cause collapse of the arch. Some people have genetically inefficient tendon, and tends to be the case in younger people. In mild cases, such as tendon splits, the posterior tibial tendon can be repaired to restore its strength. Acute incontinuity of the tendon can be primarily repaired. Often the posterior tibial tendon is augmented with a tendon transfer of an adjacent tendon to provide both strength and continuity. In any tendon repair, advanced or retensioning of the tendon is performed. In most flat foot surgery a tendon augmentation is often combined with other boney procedures to restore structure and balance to the foot. Stretching Exercises Flexibility is important in preventing injuries. With a simple stretching exercise, you can rehabilitate the muscles of your foot to relieve arch pain and prevent future injuries. This simple exercise by Tammy White and Phyllis Clapis for Relay Health is a good way to strengthen your foot muscles and stretch your plantar fascia. Sit in a chair and cross one foot over your other knee. Grab the base of your toes and pull them back toward your leg until you feel a comfortable stretch. Hold 15 seconds and repeat three times. When you can stand comfortably on your injured foot, you can begin standing to stretch the plantar fascia at the bottom of your foot. Comments are closed.
