Are Fallen Arches Flat Feet?

Overview



There are three types of flat feet: flexible flatfoot, painful rigid flatfoot, and spasmodic flatfoot. Flexible flat feet have some arch, even if the arch only appears while the person is flexing the foot or standing on their toes. Flexible flat feet may not cause pain or require treatment. Painful rigid flatfoot, on the other hand, is abnormal and causes pain, stiffness, and the inability to flex the foot. This often indicates that there is a problem with the bones in the foot, a disease is present, or an injury has occurred. Spasmodic flatfoot involves the foot being forced outward by spasmodic contractions of the peroneal muscle.

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

Not everyone who has flat feet experiences symptoms. Others, however, feel persistent pain in their feet and wearing shoes can prove additionally painful. Others only feel symptoms when they walk more than normal, go jogging or participate in a sport that involves running or kicking.

Diagnosis

Flat feet are easy to identify while standing or walking. When someone with flat feet stands, their inner foot or arch flattens and their foot may roll over to the inner side. This is known as overpronation. To see whether your foot overpronates, stand on tiptoes or push your big toe back as far as possible. If the arch of your foot doesn't appear, your foot is likely to overpronate when you walk or run. It can be difficult to tell whether a child has flat feet because their arches may not fully develop until they're 10 years of age.

What causes flat foot deformity?

Non Surgical Treatment

If you have flat feet you may not necessarily need treatment -- sometimes a child or even an adult will have low arches and have no problems. It's normal for a baby's or young child's feet to appear flat until the structure of their feet is more fully developed. If flat feet are contributing to secondary problems, especially leg or foot pain, treatment may be necessary. Flat feet can sometimes cause difficulty walking or running and interfere with athletic activities. A visit to a podiatrist will involve an evaluation of foot structure and function. Besides a foot exam, a visit may include foot X-rays and an analysis of your feet while walking. Your podiatrist may prescribe arch supports or orthotics to control the pronation. While orthotics and arch supports don't permanently correct the shape of the arch, they do help control excess pronation that may be causing wear-and-tear on your muscles and joints. Sneakers with a design called motion control are also helpful for overpronators. This style of sneaker has a design that creates more stability by limiting movement in the heel and arch area of the shoe. Additionally, physical therapy and stretching exercises may be in order, especially if tendonitis (tendon inflammation) is present. Flat feet that are the result of congenital or developmental abnormalities may require further intervention, such as bracing, casting or surgical correction. A brace incorporates an arch support into a device that attaches to the lower leg, giving extra support and flat-foot control. Bracing or foot surgery may also be warranted in cases when flat feet are caused by neurological diseases or are aggravated by posterior tibial tendonitis, which can be a long-term complication of flat feet. Casting is a method used for children whose flat feet are caused by bone positional abnormalities, such as metatarsus adductus. It involves using a series of casts to assist in re-aligning leg and foot bones to their proper anatomical position.

Surgical Treatment



Procedures may include the following. Fusing foot or ankle bones together (arthrodesis). Removing bones or bony growths, also called spurs (excision). Cutting or changing the shape of the bone (osteotomy). Cleaning the tendons' protective coverings (synovectomy). Adding tendon from other parts of your body to tendons in your foot to help balance the "pull" of the tendons and form an arch (tendon transfer). Grafting bone to your foot to make the arch rise more naturally (lateral column lengthening).

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.
