If you take a close look an adult foot (from the inside) you will notice an inward/upward curve at the center. This curve is known as an arch, and it?s formed by tendons in the foot and lower leg attached at the heel and foot bones. When these tendons pull and attach normally, the foot forms a normal arch. When the tendons don?t pull together properly, they don?t form any arch. This results in flat feet popularly known as fallen arches.Causes
Fallen arches have many causes. If you have fallen arches, or flat feet, the normal arch in the middle of your foot is not curved properly. You can have this condition called ples planus in medical terms and never have any symptoms. However, fallen arches can lead to foot pain, fatigue or more serious conditions. If fallen arches alter the way you walk, you may eventually develop knee, hip and low back pain. Your foot may lose normal range of motion making it hard to rise up onto your toes. In some cases, your feet can become swollen. If you have this condition, talk to your doctor about an appropriate treatment plan.Symptoms
Depending on the cause of the flatfoot, a patient may experience one or more of the different symptoms below. Pain along the course of the posterior tibial tendon which lies on the inside of the foot and ankle. This can be associated with swelling on the inside of the ankle. Pain that is worse with activity. High intensity or impact activities, such as running, can be very difficult. Some patients can have difficulty walking or even standing for long periods of time. When the foot collapses, the heel bone may shift position and put pressure on the outside ankle bone (fibula). This can cause pain on the outside of the ankle. Arthritis in the heel also causes this same type of pain. Patients with an old injury or arthritis in the middle of the foot can have painful, bony bumps on the top and inside of the foot. These make shoewear very difficult. Occasionally, the bony spurs are so large that they pinch the nerves which Can exercise increase your height?
result in numbness and tingling on the top of the foot and into the toes. Diabetics may only notice swelling or a large bump on the bottom of the foot. Because their sensation is affected, people with diabetes may not have any pain. The large bump can cause skin problems and an ulcer (a sore that does not heal) may develop if proper diabetic shoewear is not used.Diagnosis
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.Non Surgical Treatment
Flexible flat feet that are painless do not require treatment. If you have pain due to flexible flat feet, an orthotic (arch-supporting insert in the shoe) can bring relief. With the increased interest in running, many shoe stores carry shoes for normal feet and pronated feet. The shoes designed for pronated feet make long distance running easier and less tiring because they correct for the abnormality. Rigid or painful flat feet require evaluation by a health care provider. The treatment depends on the cause of the flat feet. For tarsal coalition, treatment starts with rest and possibly a cast. If this fails to improve the pain, surgery may be necessary. For problems with the posterior tibial tendon, treatment may start with rest, anti-inflammatory medications, and shoe inserts or ankle braces. In more advanced cases, surgery may be needed to clean or repair the tendon, or fuse some of the joints of the foot into a corrected position. Flat feet in older adults can be treated with pain relievers, orthotics, and sometimes surgery.Surgical Treatment
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.
