Overview
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.
Causes
The causes of high arched feet can vary greatly. They range from neurological disorders, club foot, injury, and often times there may be no known reason. The idea behind surgery to correct this often painful condition is to bring the arch down and thereby, allow the ground pressure of walking to be more evenly distributed across the entire bottom of the foot. Over time high arch feet can cause severe plantar calluses, ulcerations broken metatarsals and even chronically sprained ankles.
Symptoms
Repetitive exertive activity arch pain is usually sharp, and localized to a specific area, rather than the entire arch. Usually the pain occurs in the area just in front of the heel. It is present when first standing on the foot in the morning, but may decrease once you start walking around, but will, gradually becomes worse with continued walking or running. Swelling may be present. The pain subsides with rest, but stretching the arch while resting may cause the pain to return. Injury pain is constantly present, but worse when standing on the foot. This pain is localized to a specific area, but may radiate out from this area to the entire foot. The pain is sharp, and usually accompanied by swelling and occasionally “black and blue” discolorations. The pain due to the natural aging process is usually dull and aching, or stiff, and can be felt throughout the entire arch area, rather then in just one spot. This pain is present whenever weight bearing, and usually becomes worse with continued walking. The pain gradually subsides when resting, and usually does not return with stretching. Biomechanical defect pain is usually localized to a section of the arch, such as the inner, middle, outer, front, or back of the arch. This pain may be sharp or dull, but is always worse with continued walking.
Diagnosis
The doctor will take a brief history to determine how the injury occurred. If necessary, a thorough physical exam may be conducted to evaluate for any other injuries. Taking your workout shoes to the exam may also provide valuable information to the medical practitioner. Both feet will be physically and visually examined by the medical practitioner. The foot and arch will be touched and manipulated possibly with a lot of pressure and inspected to identify obvious deformities, tender spots, or any differences in the bones of the foot and arch.
Non Surgical Treatment
Doctors commonly prescribe shoe inserts, or orthotics, to support the arch. These devices make walking and standing more comfortable for a person with fallen arches, reports the American Academy of Orthopaedic Surgeons. Orthotics are typically worn with closed shoes. They are available over-the-counter or can be custom-made.
Surgical Treatment
In adults, the most common cause of collapse is due to the posterior tibial tendon tear. In such cases, the tendon must be repaired and a second tendon may be added to the posterior tibial tendon for strength and added support. If the foot is found to be very flat, bone realignment procedures or possible bone fusion procedures may be used to realign the foot. If the calf or Achilles tendon are found to be tight, they may be lengthened to allow better motion at the ankle and less arch strain. The forefoot may also be in a poor position and stabilization of the arch may be necessary to increase forefoot contact to the ground.
Prevention
Strap the arches into the anatomically correct positions with athletic tape and leave them like this for some time. If the fallen arches are an issue with the muscular structure, this may give the muscles an opportunity to strengthen. This is definitely not a fallen arches cure all the time but it can help prevent it more times than not. Ask a doctor or physical therapists to show you how to do this taping. Find shoes that fit. This may require that you get your foot measured and molded to ensure that the shoe will fit. Shoes that are too big, too tight or too short, may not directly cause the fallen arches, but they can assist with the damage to the area. These shoes should have thick cushioning inside and have plenty of room for your toes. Walk without shoes as much as possible. Shoes directly assist with weakening and distorting the arches of the feet so going without shoes can actually help strengthen your arches and prevent fallen arches. Walking on hard and bumpy surfaces barefooted makes the muscles in your feet strengthen in order to prevent injury. It is a coping mechanism by your body. Insert heel cups or insoles into the shoes that you wear the most. Many people wear uncomfortable shoes to work and these are the same shoes that cause their arches the most problems. Inserting the heel cups and insoles into these shoes can prevent fallen arches from occurring. Many people place these inserts into all their shoes to ensure support. Ask a medical professional, either your doctor or a physical therapist, about daily foot exercises that may keep the arches stronger than normal. Many times, you can find exercises and stretches on the Internet on various websites. Curling your toes tightly and rotating your feet will help strengthen your longitudinal arches. Relax your feet and shake them for a minute or so before you do any arch exercises. This will loosen the muscles in your feet that stay tight due to normal daily activities. Wear rigid soled sandals whenever possible to provide a strong support for your arches. Wooden soled sandals are the best ones if available. Walk or jog on concrete as much as you can. This will create a sturdy support for your arches. Running or walking in sandy areas or even on a treadmill, does not give rigid support. Instead, these surfaces absorb the step, offering no support for arches.
Stretching Exercises
Point your toes. To ease foot pain and aching in your feet, lift one foot and roll it downward until the toes are pointed toward the ground. Then flex your foot. Repeat using the other foot. This exercise will help stretch out all the small muscles that are on the bottom of your feet, which can help relieve aching and improve blood circulation. Raise your heels. This exercise is good for relieving toe cramps caused by standing for hours in constricting shoes, says Kurtz. Bonus: It can also strengthen calf muscles and make them look more defined. Stand up and lift your heels so that you are standing on the balls of your feet. Hold for 10 seconds. Repeat 10 times. Squeeze your toes. To strengthen the toes and help alleviate foot pain from hammertoes (when a toe resembles a claw), separate your toes using corks or foam toe separators and then squeeze your toes together for five seconds. Repeat 10 times. Roll a ball. Want to create an instant massage for the bottom of your feet? Roll a golf ball or tennis ball under the ball of your foot. Apply light pressure for about two minutes. This exercise can be helpful for arch pain, cramps, and heel pain from plantar fasciitis. Stretch standing up. A weight-bearing, runners-type stretch can be helpful for foot pain in the arch. Stand up and place your toes against a wall; lean forward a little until you feel your arch stretch. Repeat using the other foot. Stretch sitting down. Sit barefoot and cross your left leg so that your ankle rests on your right thigh. Then hold your toes and bend them back toward your shin, stretching the band of tissue connecting the bottom of the heel to the ball. A University of Rochester study found that people living with plantar fasciitis had a 75 percent chance of having no pain within three to six months of performing this stretch three times daily. Give yourself a foot massage. Nothing spells pain relief like a good foot rub. Use the following technique recommended by Rhonda Crockett, a licensed massage therapist at Ohio State University?s Center for Integrative Medicine in Columbus. Start with your toes, using your thumb to massage them in circular motions. Then move to the arch under your foot and gradually work your way down to the heel, applying pressure with your fingers and palm of your hand. Use lotion to allow your hand to move smoothly over your foot. Relax in a warm bath with Epsom salts. The combination of warm water and Epsom salts will give you a double dose of pain relief and relaxation. Magnesium sulfate, the key compound in Epsom salts, has been found to relax muscles, reduce pain, and sedate the nervous system. Plus, warm water helps improve circulation in the feet and relieve muscle pain. Crockett recommends adding two cups of Epsom salts to a warm bath and soaking for 20 minutes.
