Do Fallen Arches Require Surgery?

Overview

Flat Foot

The appearance of flat feet is normal and common in infants, partly due to "baby fat" which masks the developing arch and partly because the arch has not yet fully developed. The human arch develops in infancy and early childhood as part of normal muscle, tendon, ligament and bone growth. Training of the feet, especially by foot gymnastics and going barefoot on varying terrain, can facilitate the formation of arches during childhood, with a developed arch occurring for most by the age of four to six years. Flat arches in children usually become proper arches and high arches while the child progresses through adolescence and into adulthood.

Causes

There are many reasons why flat feet develop. Here?s a look at some of the most common causes. Genetics, weak arches, injury, arthritis, diabetes, age, wear and tear on feet, tibialis posterior (ruptured tendon). Nervous system or muscle diseases such as cerebral palsy. Weakness and tightness of other muscles and tendons higher up in the lower extremity. The way our arches form depends on several factors. Our feet are complex structures that comprise twenty-six bones, thirty-three joints, and more than 100 muscles, tendons, and ligaments each. Each foot forms two arches. The arch that runs from the heel to the toe is known as the longitudinal arch, while the one that runs the width is known as the transverse arch. Ligaments (fibrous tissues) give our arches their shape and hold our bones together. The plantar fascia (the long, strong band of connective tissue that runs along the sole of your foot) and muscles add secondary support. There are also foot pads that absorb impact and assist with weight-bearing functions. How these things intertwine and work together determines the formation of our arches. A structural abnormality or injury to one of these components can result in flatfoot.

Symptoms

Having flat feet can be painless and is actually normal in some people. But others with flat feet experience pain in the heel or arch area, difficulty standing on tiptoe, or have swelling along the inside of the ankle. They may also experience pain after standing for long periods of time or playing sports. Some back problems can also be attributed to flat feet.

Diagnosis

Determining whether you have fallen arches may be as easy as looking at the shape of the middle bottom of your foot. Is there any kind of arch there? If you cannot find any kind of arch, you may have a flat foot. There are, however, other ways to decide in case you're still not sure. Another way to figure out if you have flat feet is to look at a few pairs of your shoes. Where do you see the most wear on the heels? If you notice significant wear in the heel and the ball of the foot extending to the big toe, this means you are overpronating. Overpronators roll their feet too far inward and commonly have fallen arches. To figure out if you have flat feet, you can also do an easy test. Get the bottoms of your feet wet and then step on to a piece of paper carefully. Step off the paper and take a look at the print your foot made. If your print looks like the entire bottom of a foot, your feet are flat. People with an arch will be missing part of the foot on their print since the arch is elevated off of the paper. Regular visits to your podiatrist are highly recommended.

What does it mean when you have flat feet?

Non Surgical Treatment

Get shoes made for walking or running. One way to support your arch is to wear good-quality running or walking shoes, says Dr. Gastwirth. "These shoes generally provide good support to the foot." Add support. The top-of-the-line arch support is an orthotic insole, which may cost $900 or more and must be custom-made. "But many people with sore arches will get relief with over-the-counter arch supports for about $10," suggests Judith Smith, M.D., assistant professor of orthopedic surgery at Emory University School of Medicine in Atlanta. "The thing to remember about arch supports is that your shoe must have enough depth to accommodate them. Otherwise, you'll get a lot of rubbing on the top of your foot, or your heel will come out of the shoe." Most mens shoes are deep enough to accommodate the insoles; women should take their shoes with them to the drugstore when buying the insoles to ensure a good fit. If your heels are high, keep them wide. High heels may be your Achilles' heel--especially if you wear them constantly. "Flatter shoes are no doubt better," says Dr. Sanfilippo. Flat heels help prevent fallen arches and are kinder to your feet if fallen arches have already occurred. "If you must wear high heels, choose styles with a wide heel. Stay away from stiletto heels."

Surgical Treatment

Flat Feet

Common indications for surgery are cerebral palsy with an equinovalgus foot, to prevent progression and breakdown of the midfoot. Rigid and painful Pes Planus. To prevent progression, eg with a Charcot joint. Tibialis posterior dysfunction, where non-surgical treatment is unsuccessful. Possible surgical procedures include Achilles tendon lengthening. Calcaneal osteotomy, to re-align the hindfoot. Reconstruction of the tibialis posterior tendon. For severe midfoot collapse of the arch, triple arthrodesis may be indicated.

Prevention

Well-fitted shoes with good arch support may help prevent flat feet. Maintaining a healthy weight may also lower wear and tear on the arches.

After Care

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.
