Posterior tibial tendon dysfunction is one of several terms to describe a painful, progressive flatfoot deformity in adults. Other terms include posterior tibial tendon insufficiency and adult acquired flatfoot. The term adult acquired flatfoot is more appropriate because it allows a broader recognition of causative factors, not only limited to the posterior tibial tendon, an event where the posterior tibial tendon looses strength and function. The adult acquired flatfoot is a progressive, symptomatic (painful) deformity resulting from gradual stretch (attenuation) of the tibialis posterior tendon as well as the ligaments that support the arch of the foot.
The cause of this condition is too much pressure exerted on the arches, and although common in athletes, the condition can happen because you went hiking or climbing, you were lifting heavy objects, or you simply walked too far too vigorously. Pregnancy places extra strain on the arches because of both the additional body weight and the effect of hormones on muscles and ligaments.
Experiencing chronic pain of any kind can lead to feelings of fatigue, irritability and even depression. Friends may joke about having 'tired dogs' after a long day, but this is completely different from your experience if arch pain has begun to impact your life on a daily basis. You may dread getting out of bed in the morning and wonder how you're going to get through a work day without having to limp home at the end of it.
In a person of any age, the doctor will ask about occupational and recreational activities, previous foot trauma or foot surgery and the type of shoes worn. The doctor will examine your shoes to check for signs of excessive wear. Worn shoes often provide valuable clues to gait problems and poor bone alignment. The doctor will ask you to walk barefoot to evaluate the arches of the feet, to check for out-toeing and to look for other signs of poor foot mechanics.
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.
If you have pain that has not been responsive to other treatments, there is a new non-surgical treatment that was recently approved by the FDA. ESWT (extracorporeal shockwave therapy) uses strong electrohydraulic acoustic (sound) energy that triggers the body?s natural repair mechanism. This treatment method is safe, effective and requires a very short recovery period compared to older surgical techniques.
Stretch and strengthen important muscles in your feet, ankles and legs in order to guard against future strain. Make sure to acquire suitable arch supports and inserts if necessary, and that your shoes are shock absorbent and in good condition. Wearing tattered shoes provides no protection, and runners should replace their footwear before exceeding 500 miles of usage. Athletes new to arch supports should gradually build their training routine, allowing their feet to become accustomed to a new stance.
