Managing Pes Planus

Overview

Adult Acquired Flat Foot

The condition known as ?fallen arches? is also referred to as flat feet or pes planus. It arises when the arch of the foot collapses to the point that the entire sole is flat to the ground. It is commonly seen in young children who have yet to develop the muscles in the sole of their feet. In most cases as a child develops and learns how to walk the finer intrinsic muscles that support the sole of the foot will develop normally and an arch forms. However in a small number of cases these muscles don?t form properly and thus neither does the arch. Fallen arches which are acquired in adulthood may be due to a number of factors.

Causes

There are a number of different causes that can lead to flat feet or fallen arches. These include, birth defects, while technically not a defect as such, flat feet can be a normal finding in patients from birth. However, a condition called tarsal coalition may occur where some of the bones in the foot are fused together resulting in a flatfoot. Inflammation or damage of the posterior tibial tendon. This tendon forms the end of a muscle that connects the lower leg to the foot, winding around the ankle and attaching to the inner aspect where the arch is normally present. The main role of the posterior tibial tendon is to invert the foot and maintain the arch height throughout the gait cycle. Torn muscles of the leg and foot can cause flat feet. Problems with the nerve supply to the muscles can result in reduction in tone and fallen arches. Fracture dislocation of the bones in the foot. Severe arthritis. While these are the common causes that can result in fallen arches and flat feet, it is important to recognise that there are certain risk factors that can also lead to this condition. These include advancing age, diabetes mellitus, high blood pressure, obesity and pregnancy.

Symptoms

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.

Diagnosis

Most children and adults with flatfeet do not need to see a physician for diagnosis or treatment. However, it is a good idea to see a doctor if the feet tire easily or are painful after standing, it is difficult to move the foot around or stand on the toes, the foot aches, especially in the heel or arch, and there is swelling on the inner side of the foot, the pain interferes with activity or the person has been diagnosed with rheumatoid arthritis. Most flatfeet are diagnosed during physical examination. During the exam, the foot may be wetted and the patient asked to stand on a piece of paper. An outline of the entire foot will indicate a flattened arch. Also, when looking at the feet from behind, the ankle and heel may appear to lean inward (pronation). The patient may be asked to walk so the doctor can see how much the arch flattens during walking. The doctor may also examine the patient's shoes for signs of uneven wear, ask questions about a family history of flatfeet, and inquire about known neurological or muscular diseases. Imaging tests may be used to help in the diagnosis. If there is pain or the arch does not appear when the foot is flexed, x-rays are taken to determine the cause. If tarsal coalition is suspected, computed tomography (CT scan) may be performed, and if an injury to the tendons is suspected, magnetic resonance imaging (MRI scan) may be performed.

How do you get an arch in your foot?

Non Surgical Treatment

Most flexible flat feet are asymptomatic, and do not cause pain. In these cases, there is usually no cause for concern, and the condition may be considered a normal human variant. Flat feet were formerly a physical-health reason for service-rejection in many militaries. However, three military studies on asymptomatic adults (see section below), suggest that persons with asymptomatic flat feet are at least as tolerant of foot stress as the population with various grades of arch. Asymptomatic flat feet are no longer a service disqualification in the U.S. military.

Surgical Treatment

Acquired 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

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.

After Care

Time off work depends on the type of work as well as the surgical procedures performed. . A patient will be required to be non-weight bearing in a cast or splint and use crutches for four to twelve weeks. Usually a patient can return to work in one to two weeks if they are able to work while seated. If a person's job requires standing and walking, return to work may take several weeks. Complete recovery may take six months to a full year. Complications can occur as with all surgeries, but are minimized by strictly following your surgeon's post-operative instructions. The main complications include infection, bone that is slow to heal or does not heal, progression or reoccurrence of deformity, a stiff foot, and the need for further surgery. Many of the above complications can be avoided by only putting weight on the operative foot when allowed by your surgeon.
