Overview
Most of us have a low arch. The foot actually appears quite normal and a clear (but low) arch is present under the foot, especially when sitting down. The situation changes with weight bearing: when we get up the arch lowers. When we start walking the arches collapse and the ankles roll inwards. This is called over-pronation - or fallen arches. Over-pronation is not the same as flat feet as often noted. Pronation itself is not wrong as we need to pronate and supinate as part of our gait. Pronation (rolling in) acts as a shock absorbing process and supination (rolling out) helps to propel our feet forward.
Causes
There are many different causes of flat feet, which can be separated into two main categories. The first category, congenital flat foot, is a condition that one is born with or is predisposed to at birth. This type includes the completely asymptomatic, pediatric flexible flat foot-by far the most common form of congenital flat foot. Flexible means that an arch is present until weight is put on the foot, at which time the arch disappears. This foot type is a result of the fact that all people are born with different physical features. Some people have bigger noses than others, just as some people have flatter feet (of course, there is no known correlation between the two). Any alteration in the many building blocks of the foot can influence its shape. At the other end of the spectrum, yet within the same category of congenital flat foot, exist several rare, more severe forms of flat foot. These severe conditions include Vertical Talus, Congenital Calcaneal Valgus, and Tarsal Coalitions - all of which are more rigid (no arch with or without weight on the foot) and definitely symptomatic. Luckily, these are much less common, but can usually be identified by specialists at the time of presentation and treated appropriately. The second category, acquired flat foot, develops over time, rather than at birth. Many different factors can contribute to the development of flat feet. These include the types of shoes a child wears, a child's sitting or sleeping positions, compensation for other abnormalities further up the leg, or more severe factors such as rupture of ligaments or tendons in the foot. Very commonly, the reason for flat feet is that the foot is compensating for a tight Achilles tendon. If the Achilles tendon is tight, then it causes the foot to point down, or to plantarflex (as occurs when stepping on the accelerator of your car). Even minimal amounts of plantarflexion can simulate a longer leg on that particular side, assuming that the other foot is in the normal position. The body therefore tries to compensate by pronating, or flattening out the arch, thereby making up for the perceived extra length on the affected side.
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
You can test yourself to see if you have flat feet or fallen arches by using a simple home experiment. First, dip your feet in water. Then step on a hard flat surface, like a dry floor or a piece of paper on the floor, where your footprints will show. Step away and examine your foot prints. If you see complete/full imprints of your feet on the floor, you may have fallen arches. However, it?s important to seek a second option from a podiatrist if you suspect you have fallen arches so they can properly diagnose and treat you.
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.
Prevention
Wear Supportive Footwear. Spend the money it takes to get proper fitting and quality footwear with good arch supports. Most sufferers of fallen arches and plantar fasciitis are born with high arches that sag as they get older. Good footwear can prevent this from becoming a problem. Flat feet, however, can become just as problematic. So, really we should all be wearing good footwear to avoid this potentially painful condition. Take It Easy. If your heel starts to hurt, take a rest. If the pain doesn?t go away after several days of resting, it may be time to see a podiatrist. Orthotics. Special insoles to support the arch of the foot can provide some much needed help. You can buy these at your local drugstore (not recommended), or you can have them specially made and custom fit for your feet. It can take awhile to get just the right one for your foot, but sometimes it can be just what you needed. Weight Control. Yes, maintaining a sensible diet with your ideal weight can be beneficial in many ways. It makes sense to think that the more weight your arches are supporting, the more easily they will fall and become painful.
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 non-union (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.
