Fallen arches, or flatfoot, is a condition in which the arch on the inside of the foot is flat and the entire sole of the foot rests on the ground. It affects about 40% of the general population. Although flat feet in themselves are not usually problematic, they can create problems in the feet, hips, ankles and knees. Pain may be experienced in the lower back if there are alignment problems and if the individual is engaged in a lot of heavy, high impact activities that put stress on the bones and muscles in the lower legs. The arches of most individuals are fully developed by the age of 12 to 13. While some people are born with flat arches, for others the arches fall over time. The tibial tendon, which runs along the inside of the ankle from above the ankle to the arch, can weaken with age and with heavy activity. The posterior tendon, main support structure for the arch, can become inflamed (tendonitis) or even tear if overloaded. For women, wearing high heels can affect the Achilles tendon and alter the structure and function of the ankle. The posterior tibial tendon may compensate for this stress and break down, causing the arches to fall. Obesity is another contributing factor, as well as a serious injury to the ankle or foot, arthritis and bad circulation such as occurs with diabetes.
Inflammatory arthritis, such as rheumatoid arthritis, can cause a painful flatfoot. This type of arthritis attacks not only the cartilage in the joints, but also the ligaments that support the foot. Inflammatory arthritis not only causes pain, but also causes the foot to change shape and become flat. The arthritis can affect the back of the foot or the middle of foot, both of which can result in a fallen arch. An injury to the ligaments in the foot can cause the joints to fall out of alignment. The ligaments support the bones and prevent them from moving. If the ligaments are torn, the foot will become flat and painful. This more commonly occurs in the middle of the foot (Lisfranc injury), but can also occur in the back of the foot. In addition to ligament injuries, fractures and dislocations of the bones in the midfoot can also lead to a flatfoot deformity. People with diabetes or with a nerve problem that limits normal feeling in the feet, can have arch collapse. This type of arch collapse is typically more severe than that seen in patients with normal feeling in their feet. This is because patients do not feel pain as the arch collapses. In addition to the ligaments not holding the bones in place, the bones themselves can sometimes fracture and disintegrate, without the patient feeling any pain. This may result in a severely deformed foot that is very challenging to correct with surgery. Special shoes or braces are the best method for dealing with this problem.
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.
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 (pes planus) it does not mean you will have problems or pain. Flat feet are a common condition. Flat feet are defined as an abnormal lowering of the medial longitudinal arch. There is often a hereditary component to the development of flat feet. Flat feet are more common in certain ethnic groups. Flat feet usually occurs equally in both feet and become apparent at an early age. Flat feet can initially be asymptomatic, but can become progressively symptomatic with age. Some flat feet never become bothersome. The medial arch is unstable in flexible flatfoot. The foot can bend as the heel lifts of the ground. This creates stress on the surrounding soft-tissues and joints creating tired, sore arches. The instability of the foot can create abnormal stress that flows up the leg which results in pain in the legs, knees, hips and lower back. Patients with flat feet often present to the chiropodist/podiatrist with problems that are indirectly caused by their foot structure.
Rarely does the physician use surgery to correct a foot that is congenitally flat, which typically does not cause pain. If the patient has a fallen arch that is painful, though, the foot and ankle physicians at Midwest Orthopaedics at Rush may perform surgery to reconstruct the tendon and "lift up" the fallen arch. This requires a combination of tendon re-routing procedures, ligament repairs, and bone cutting or fusion procedures.
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 nonunion (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.
