Flat feet is the most common foot deformity known. In fact, sixty million Americans or 25% of the U.S. population have flat feet. Some of these people may experience problems that limit their activities, while others can run marathons or play in the NBA. If you've ever seen your footprints in the sand and they looked more like bricks than feet, then you probably have flat feet. Simply stated, a flat foot is a foot that does not have an arch when standing. In the medical world, flat feet are associated with "pronated" feet. Pronated is merely the term used to describe the position of the foot when it is flexed upward (dorsiflexed), turned away from the body (abducted), and the heel is rolled outward (everted), all at the same time. A certain amount of pronation is required for normal walking, but too much pronation is often considered a foot's "worst enemy." Over time, excessive pronation can lead to many unpleasant problems including heel pain, bunions, hammertoes, shin splints, and even knee, hip, or back pain. In fact, one orthopedic surgeon discovered that 95% of his total knee replacement patients and 90% of his total hip replacement patients had flat feet. An easy way to tell if you pronate too much is to take a look at your athletic shoes-excessive wearing of the inside heel (arch side of the shoe) as compared to the outside is a classic indication of excessive pronation.
Fallen arches in adults are caused by several things. Below are some of the most common causes. Abnormalities present from birth. Torn or stretched tendons (resulting from foot injuries or foot strains). Inflammation or damage of the PTT (posterior tibial tendon). The PTT is responsible for connecting the middle of the arch to the ankle and lower leg. Dislocated or broken bones (also as a result of injury). Health problems like rheumatoid arthritis. Nerve problems. Other factors like diabetes, obesity, aging and pregnancy (these factors are known to increase the risk of fallen arches).
Pain and stiffness of the medial arch or anywhere along the mid-portion of the foot. Associated discomfort within and near the ankle joint. The knees, hips, and lower back may be the primary source of discomfort. Feet may often feel tired and achy. Painful shin splints may develop with activity. Gait may be awkward.
If your child has flatfeet, his or her doctor will ask about any family history of flatfeet or inherited foot problems. In a person of any age, the doctor will ask about occupational and recreational activities, previous foot trauma or foot surgery and the type of shoes worn. The doctor will examine your shoes to check for signs of excessive wear. Worn shoes often provide valuable clues to gait problems and poor bone alignment. The doctor will ask you to walk barefoot to evaluate the arches of the feet, to check for out-toeing and to look for other signs of poor foot mechanics. The doctor will examine your feet for foot flexibility and range of motion and feel for any tenderness or bony abnormalities. Depending on the results of this physical examination, foot X-rays may be recommended. X-rays are always performed in a young child with rigid flatfeet and in an adult with acquired flatfeet due to trauma.

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.
Surgery for flat feet is separated into three kinds: soft tissue procedures, bone cuts, and bone fusions. Depending on the severity of the flat foot, a person?s age, and whether or not the foot is stiff determines just how the foot can be fixed. In most cases a combination of procedures are performed. With flexible flat feet, surgery is geared at maintaining the motion of the foot and recreating the arch. Commonly this may involve tendon repairs along the inside of the foot to reinforce the main tendon that lifts the arch. When the bone collapse is significant, bone procedures are included to physically rebuild the arch, and realign the heel. The presence of bunions with flat feet is often contributing to the collapse and in most situations requires correction. With rigid flat feet, surgery is focused on restoring the shape of the foot through procedures that eliminate motion. In this case, motion does not exist pre-operatively, so realigning the foot is of utmost importance. The exception, are rigid flat feet due to tarsal coalition (fused segment of bone) in the back of the foot where freeing the blockage can restore function.
