You Could Have Pes Planus
Overview
Feet are very variable in shape within and between ethnic groups as well as in populations generally. There is not a normal profile but a wide variation with people with foot profiles at the extremes being very high arched or very low arched, with most people somewhere nearer the middle. What do you do when your Achilles tendon hurts? will dictate the general profile of a foot is the bony shape and the soft tissue support. The first thing to say about flat feet and fallen arches is that they are not medical terms and therefore have different meaning to different people. Therefore this question is not as easy as it first might seem. Pes Planus is the medical term for flat feet.
Causes
There is a lack of normal arch development, probably due to inherent ligamentous laxity. Around 20% of adults have Pes planus. The majority have a flexible flat foot and no symptoms. However, if there is also heel cord contracture, there may be symptoms (see 'Contributing factors', below). Loss of support for the arch. Dysfunction of the tibialis posterior tendon, a common and important cause. Tear of the spring ligament (rare). Tibialis anterior rupture (rare). A neuropathic foot, e.g from diabetes, polio, or other neuropathies. Degenerative changes in foot and ankle joints. Inflammatory arthropathy, eg rheumatoid arthritis. Osteoarthritis. Fractures. Bony abnormalities, eg tarsal coalition.
Symptoms
The majority of children and adults with flexible flatfeet never have symptoms. However, their toes may tend to point outward as they walk, a condition called out-toeing. A person who develops symptoms usually complains of tired, aching feet, especially after prolonged standing or walking. Symptoms of rigid flatfoot vary depending on the cause of the foot problem. Congenital vertical talus. The foot of a newborn with congenital vertical talus typically has a convex rocker-bottom shape. This is sometimes combined with an actual fold in the middle of the foot. The rare person who is diagnosed at an older age often has a "peg-leg" gait, poor balance and heavy calluses on the soles where the arch would normally be. If a child with congenital vertical talus has a genetic disorder, additional symptoms often are seen in other parts of the body. Tarsal coalition. Many people have no symptoms, and the condition is discovered only by chance when an X-ray of the foot is obtained for some other problem. When symptoms occur, there is usually foot pain that begins at the outside rear of the foot. The pain tends to spread upward to the outer ankle and to the outside portion of the lower leg. Symptoms usually start during a child's teenage years and are aggravated by playing sports or walking on uneven ground. In some cases, the condition is discovered when a child is evaluated for unusually frequent ankle sprains. Lateral subtalar dislocation. Because this often is caused by a traumatic, high-impact injury, the foot may be significantly swollen and deformed. There also may be an open wound with bruising and bleeding.
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.
Non Surgical Treatment
If the flat foot is rigid and causing problems, you will be referred to a foot specialist. Talk with your doctor about the best treatment plan for you. Options include the following. Physical Therapy and Exercises. Physical therapy may relieve discomfort. You may be given a specific stretching and strength program. You may also have treatment to help manage the discomfort. Exercises can help with the strength of the surrounding muscles. It may relieve some of the pressure in the foot. Orthotics are shoe inserts that support the foot. These inserts may help to reduce pain and disability in some people. In mild cases, a well-fitting pair of shoes with arch support may be all that is needed. Flat feet caused by nerve or muscle disease may need special braces. Fallen arches are usually treated using stretching exercises, physical therapy and medication (to reduce inflammation). In extreme cases however, surgery is recommended.
Surgical Treatment
Generally one of the following procedures is used to surgically repair a flat foot or fallen arch. Arthrodesis. One or more of your bones in the foot or ankle are fused together. Osteotomy. Correcting alignment by cutting and reshaping a bone. Excision. Removing a bone or a bone spur. Synovectomy. Cleaning the sheath that covers the tendon. Tendon transfer. Using a piece of one tendon to lengthen or replace another. Arthroereisis. placing a small device in the subtalar joint to limit motion. For most people, treatment is successful, regardless of the cause, although the cause does does play a major role in determining your prognosis. Some causes do not need treatment, while others require a surgical fix.
