There are many different causes of and treatments for flat foot. The most important part of treatment is determining the exact flat foot type on an individual basis, and doing so early on. The main objective is to become educated on the potential problems, so that you can stop them before they start. Conservative treatment is often successful if initiated early. The old adage "a stitch in time saves nine" definitely applies to the human body, hopefully more figuratively than literally. Do not ignore what your common sense and your body are telling you. Yes, you can live without an arch, but never neglect a symptomatic foot. If you neglect your feet, they will make you pay with every literal step you take.
Some people develop fallen arches because they tend to pronate, or roll inwards on the ankles, says the Instep Foot Clinic. Other people may simply have under-developed muscles in their arches. Your arches help your feet bear weight and are supported in this job by muscles and tendons in your feet and ankles. So, while fallen arches aren?t usually serious, they can cause pain in your feet, ankles, knees and/or hips due to your reduced weight-bearing ability. In these cases, treatment may be required. Orthotics that sit in your shoes and support your arches are a common solution, as are exercises to strengthen and stretch your feet and leg muscles.
Pain along the inside of the foot and ankle, where the tendon lies. This may or may not be associated with swelling in the area. Pain that is worse with activity. High-intensity or high-impact activities, such as running, can be very difficult. Some patients can have trouble walking or standing for a long time. Pain on the outside of the ankle. When the foot collapses, the heel bone may shift to a new position outwards. This can put pressure on the outside ankle bone. The same type of pain is found in arthritis in the back of the foot. The symptoms of PTTD may include pain, swelling, a flattening of the arch, and an inward rolling of the ankle. As the condition progresses, the symptoms will change. For example, when PTTD initially develops, there is pain on the inside of the foot and ankle (along the course of the tendon). In addition, the area may be red, warm, and swollen. Later, as the arch begins to flatten, there may still be pain on the inside of the foot and ankle. But at this point, the foot and toes begin to turn outward and the ankle rolls inward. As PTTD becomes more advanced, the arch flattens even more and the pain often shifts to the outside of the foot, below the ankle. The tendon has deteriorated considerably and arthritis often develops in the foot. In more severe cases, arthritis may also develop in the ankle.
An examination of the foot is enough for the health care provider to diagnose flat foot. However, the cause must be determined. If an arch develops when the patient stands on his or her toes, the flat foot is called flexible and no treatment or further work-up is necessary. If there is pain associated with the foot or if the arch does not develop with toe-standing, x-rays are necessary. If a tarsal coalition is suspected, a CT scan is often ordered. If a posterior tibial tendon injury is suspected, your health care provider may recommend an MRI.
Non Surgical Treatment
The type of treatment will depend on the stage of PTTD present. There are four stages of posterior tibial tendon dysfunction. Stage I. The posterior tibial tendon is inflamed but has normal strength. There is little to no change in the arch of the foot. The patient can still perform a single-limb heel rise and has a flexible hindfoot. Orthotic treatment options include modified off the shelf inserts and custom molded orthotics. Stage 2. The tendon is partially torn or shows degenerative changes and as a result loses strength.There is considerable flattening of the arch without arthritic changes in the foot. The patient cannot perform single-limb heel rise. Pain is now present on the lateral aspect of the ankle. Orthotic treatment is similar as that in stage I, with the addition of more rigid arch supports and wedging. Stage 3. Results when the posterior tibial tendon is torn and not functioning. As a result the arch is completely collapsed with arthritic changes in the foot. A solid ankle AFO is suggested in conjunction with a modified orthopedic shoe. Stage 4. Is identical to stage three except that the ankle joint also becomes arthritic. A rigid AFO and modified orthopedic shoe is required.
Feet that do not respond to the treatments above may need surgery. The surgery will help to create a supportive arch.
