Most people (approx. 60-70% of the population) suffer from excessive pronation due to flat feet when walking, running and standing. Though the foot may appear normal when sitting down, with a clear arch present under the foot, over-pronation becomes noticeable when we stand or walk as a result of weight bearing. The arches collapse with every step we take, and the ankles roll inwards. This is called overpronation, a biomechanical imbalance that can lead to many painful foot conditions such as heel pain, plantar fasciitis, heel spurs, tendonitis, and can even affect other parts of your body such as the knees and lower back.
Fallen arches can be the result of other conditions such as overuse, stretching or tearing of the posterior tibial tendon (which attaches to a bone in the foot and runs up the calf of the lower leg at a tension which pulls up the arch) which reduces its ability to maintain tension in the tendon. Whether or not the condition is caused by overpronation, this is the likely outcome for runners, whose arches are no longer strong enough to take the constant strain of bearing the body?s weight on impact, causing joint, postural and muscular problems.
It?s possible to have fallen arches and experience no symptoms whatsoever. But many people do notice some problems with this condition. Their feet, back and legs ache. Standing on their toes is difficult, if not impossible, and they note swelling around the arch and heel.
It is important for people with foot pain to know if they have flat feet. The following tests can help you determine your arch type. When you get out of a swimming pool, look at your footprint on the concrete. The front of the foot will be joined to the heel by a strip. If your foot is flat, then the strip is the same width as the front of the foot, creating a footprint that looks like a stretched out pancake. With a normal arch, the strip is about half the width of the front of the foot. If you have a high arch, only a thin strip connects the front of the foot with the heel. Put your shoes on a flat table and view them at eye level from behind. See if the sole is worn evenly. A flat foot will cause more wear on the inside of the sole, especially in the heel area. The shoe will easily rock side to side. A flat foot will also cause the upper part of the shoe to lean inward over the sole. Both shoes should wear about the same way. If you have pain in one foot, you should make sure you don't have a fallen arch on that side. There are two good tests you can perform at home to detect this problem. Place your fingertips on a wall that you are directly facing and stand on your tiptoes on one foot. If you can't do it, a fallen arch may be the culprit. Stand with your feet parallel. Have someone stand in back of you and look at your feet from behind. You can also do it yourself if you stand with your back to a mirror. Normally, only the pinky toe is visible from behind. If one foot is flatter than the other, the 4th and sometimes the 3rd toe on that foot can also be seen.

Non Surgical Treatment
If you have flat feet, you may also experience pain throughout the lower body and into the lower back. Orthotics (custom-made rigid foot supports) can be prescribed when over-the-counter supports do not provide releif and surgery can also offer a more permanent solution in severe cases. The board-certified doctors in our practice would be able to select the most appropriate course of action in each case.
Surgery is typically offered as a last resort in people with significant pain that is resistant to other therapies. The treatment of a rigid flatfoot depends on its cause. Congenital vertical talus. Your doctor may suggest a trial of serial casting. The foot is placed in a cast and the cast is changed frequently to reposition the foot gradually. However, this generally has a low success rate. Most people ultimately need surgery to correct the problem. Tarsal coalition. Treatment depends on your age, extent of bone fusion and severity of symptoms. For milder cases, your doctor may recommend nonsurgical treatment with shoe inserts, wrapping of the foot with supportive straps or temporarily immobilizing the foot in a cast. For more severe cases, surgery is necessary to relieve pain and improve the flexibility of the foot. Lateral subtalar dislocation. The goal is to move the dislocated bone back into place as soon as possible. If there is no open wound, the doctor may push the bone back into proper alignment without making an incision. Anesthesia is usually given before this treatment. Once this is accomplished, a short leg cast must be worn for about four weeks to help stabilize the joint permanently. About 15% to 20% of people with lateral subtalar dislocation must be treated with surgery to reposition the dislocated bone.
Patients may go home the day of surgery or they may require an overnight hospital stay. The leg will be placed in a splint or cast and should be kept elevated for the first two weeks. At that point, sutures are removed. A new cast or a removable boot is then placed. It is important that patients do not put any weight on the corrected foot for six to eight weeks following the operation. Patients may begin bearing weight at eight weeks and usually progress to full weightbearing by 10 to 12 weeks. For some patients, weightbearing requires additional time. After 12 weeks, patients commonly can transition to wearing a shoe. Inserts and ankle braces are often used. Physical therapy may be recommended. There are complications that relate to surgery in general. These include the risks associated with anesthesia, infection, damage to nerves and blood vessels, and bleeding or blood clots. Complications following flatfoot surgery may include wound breakdown or nonunion (incomplete healing of the bones). These complications often can be prevented with proper wound care and rehabilitation. Occasionally, patients may notice some discomfort due to prominent hardware. Removal of hardware can be done at a later time if this is an issue. The overall complication rates for flatfoot surgery are low.
