They make it possible for us to walk, run, and stand. With over two dozen bones, your feet are really a masterpiece of engineering. But sometimes even the best made things have flaws. One common problem is to have flatfeet, or fallen arches.
As children grow, their legs will experience developmental changes that can result in excess flattening of the arches with weight bearing. One example is genu valgum, or knock-knees, a usually normal, temporary condition in children at different stages of growth. A tight calf muscle or Achilles tendon can also contribute to a flat foot. Many children will experience tight calf muscles as they go through growth spurts. Conditions that are present at birth and are often diagnosed early include: metatarsus adductus, calcaneovalgus and congenital vertical talus. Tarsal coalitions are congenitally fused foot bones that cause a rigid flat foot often associated with painful muscle spasms. This type of flat foot is usually diagnosed later in childhood or in adulthood. Any condition that causes loose ligaments can result in a flat foot or lower-than-normal arch. Ligaments are bands of tissue that connect bones to each other and have an important role in giving form to foot arches. An example of a condition that causes loosening of ligaments is pregnancy, where normal hormonal changes relax the ligaments. Diseases that cause loose ligaments include Ehlers-Danlos syndrome, Marfan's syndrome and rheumatoid arthritis. If one leg is longer than the other, one foot may be flat in relation to the other to compensate. Usually the foot on the longer limb will have a flatter arch in an effort to shorten that limb, balancing-out the unevenness. Leg length inequality can be caused by spinal abnormalities such as scoliosis. It can also be due to an actual difference in length of one leg bone compared to the other.
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 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 of flat feet or fallen arches can be made by your health practitioner and is based on the following. Clinical assessment involving visual gait assessment, as well as biomechanical assessment. A detailed family and medical history. A pain history assessment determining the location of painful symptoms. Physical palpation of the feet and painful areas. Imaging such as MRI or x-ray can be used by your practitioner to assist in the diagnosis.

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 podiatrist. 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.
A combination of surgical procedures can be used to reconstruct the flatfoot. Generally, these procedures can be separated into those that correct deformities of the bones and those that repair ligaments and tendons. Your orthopaedic surgeon will choose the proper combination of procedures for your foot. Surgery of the foot can be performed under regional anesthesia, which is numbing the foot and ankle with a nerve or spinal block, or general anesthesia, which may require a breathing tube. A nerve block is often placed behind the knee to reduce pain after surgery.
Donning a first-rate pair of arch supports, therapeutic socks and proper footwear before heading out to enjoy hours of holiday fun is one option to consider. Your podiatrist can help you find just the right ones. Once you have them on, they?ll help ease the amount of pressure being put on your body and keep the blood flowing in the right direction. While you?re standing in line, consider doing a bit of exercise as well. We?re not talking about channeling your inner Jack LaLanne here. Otherwise, you might attract the attention of the mall security guards. Simple ankle rotations and walking in place may help to reduce edema and give your flat feet a bit of a break. If you happen to be in a shopping mall or center where foot massages are available, take advantage of them periodically. They are likely to make you feel better and it?s a great excuse to carve out a few quiet moments for yourself. If you can?t visit a professional, tuck a personal foot massager into your purse. That way, you can lightly massage your own feet during the car ride home. Lastly, there are certain foods and nutritional supplements available that may reduce edema caused by standing on flat feet for hours at a time. The list includes potassium rich foods like raisins, bananas, baby carrots, nuts and yogurt. So, you may want to pack a snack for those trips to the mall or hit the food court before you hit the stores.
