Some people have always had flat feet from a young age. Unfortunately as people reach their fifties they will suddenly have one foot with a flatter arch than the other foot. This situation is termed adult acquired flatfoot. Adult acquired flatfoot is a painful condition occurring in one foot. The common patient profile is a female over the age of 50 with pre-existing flatfeet, high blood pressure, high cholesterol, diabetes and obesity. All of these underlying problems will lead to a weakening of the support structures of the arch. If you have adult acquired flat foot you will not be able to lift your heel off the ground while standing on one leg. Adult acquired flatfoot may develop due to trauma or degeneration of major tendons ankle & foot. Weakness or paralysis of leg muscles can also create a flatfoot deformity. Adult acquired flat foot can be treated with physical therapies, motion control running shoes or hiking boots, custom foot orthoses, and ankle foot orthoses.
Aging, injury, overuse, or illness can result in fallen arches or a fallen arch on one side. Diabetes. Obesity. Pregnancy. Nerve conditions. Foot abnormalities present since birth. Broken or dislocated bones in the foot. Stretched or torn tendons. Medical conditions such as arthritis. Sudden weight gain
Flat feet may not cause any symptoms at all. Rigid flat feet may cause pain, calluses, blisters, or skin redness on the inner side of the foot. A stiff foot, weakness or numbness of the foot, Rapid wearing out of shoes-worn shoes lean in toward each other. Difficulty or pain with activities like running-in the foot, knee or hip.
Most children and adults with flatfeet do not need to see a physician for diagnosis or treatment. However, it is a good idea to see a doctor if the feet tire easily or are painful after standing, it is difficult to move the foot around or stand on the toes, the foot aches, especially in the heel or arch, and there is swelling on the inner side of the foot, the pain interferes with activity or the person has been diagnosed with rheumatoid arthritis. Most flatfeet are diagnosed during physical examination. During the exam, the foot may be wetted and the patient asked to stand on a piece of paper. An outline of the entire foot will indicate a flattened arch. Also, when looking at the feet from behind, the ankle and heel may appear to lean inward (pronation). The patient may be asked to walk so the doctor can see how much the arch flattens during walking. The doctor may also examine the patient's shoes for signs of uneven wear, ask questions about a family history of flatfeet, and inquire about known neurological or muscular diseases. Imaging tests may be used to help in the diagnosis. If there is pain or the arch does not appear when the foot is flexed, x-rays are taken to determine the cause. If tarsal coalition is suspected, computed tomography (CT scan) may be performed, and if an injury to the tendons is suspected, magnetic resonance imaging (MRI scan) may be performed.
What causes flat foot deformity?
Non Surgical Treatment
Some patients with flat feet may automatically align their limbs in such a way that unpleasant symptoms never develop. In such cases treatment is not usually required. Pain in the foot that is caused by flat feet may be alleviated if the patient wears supportive well-fitted shoes. Some patients say that symptoms improve with extra-wide fitting shoes. Fitted insoles or orthotics (custom-designed arch supports) may relieve pressure from the arch and reduce pain if the patient's feet roll or over-pronate. The benefits of an orthotic only exist while it is being worn. Patients with tendonitis of the posterior tibial tendon may benefit if a wedge is inserted along the inside edge of the orthotic - this takes some of the load off the tendon tissue. Wearing an ankle brace may help patients with posterior tibial tendinitis, until the inflammation comes down. Rest, doctors may advise some patients to rest and avoid activities which may make the foot (feet) feel worse, until the foot (feet) feels better. A combination of an insole and some kind of painkiller may help patients with a ruptured tendon, as well as those with arthritis. Patients with a ruptured tendon or arthritis who find insoles with painkillers ineffective may require surgical intervention. Patients, usually children, whose bones did not or are not developing properly, resulting in flat feet from birth, may require surgical intervention to separate fused bones (rare). Bodyweight management, if the patient is obese the doctor may advise him/her to lose weight. A significant number of obese patients with flat feet who successfully lose weight experience considerable improvement of symptoms.
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.
Well-fitted shoes with good arch support may help prevent flat feet. Maintaining a healthy weight may also lower wear and tear on the arches.
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.
