The appearance of flat feet is normal and common in infants, partly due to "baby fat" which masks the developing arch and partly because the arch has not yet fully developed. The human arch develops in infancy and early childhood as part of normal muscle, tendon, ligament and bone growth. Training of the feet, especially by foot gymnastics and going barefoot on varying terrain, can facilitate the formation of arches during childhood, with a developed arch occurring for most by the age of four to six years. Flat arches in children usually become proper arches and high arches while the child progresses through adolescence and into adulthood. A survey of 297 suburban school children up to the age of 10 years at Allahabad in U.P. in India revealed 40.32% children under 5 years, 22.15% children between 5-10 years and 15.48% children above 10 years but below 15 years having bilateral flat foot.
Fallen arches can be the result of other conditions such as overuse, stretching or tearing of the posterior tibial tendon (which attaches to a bone in the foot and runs up the calf of the lower leg at a tension which pulls up the arch) which reduces its ability to maintain tension in the tendon. Whether or not the condition is caused by overpronation, this is the likely outcome for runners, whose arches are no longer strong enough to take the constant strain of bearing the body?s weight on impact, causing joint, postural and muscular problems.
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.
It is important for people with foot pain to know if they have flat feet. The following tests can help you determine your arch type. When you get out of a swimming pool, look at your footprint on the concrete. The front of the foot will be joined to the heel by a strip. If your foot is flat, then the strip is the same width as the front of the foot, creating a footprint that looks like a stretched out pancake. With a normal arch, the strip is about half the width of the front of the foot. If you have a high arch, only a thin strip connects the front of the foot with the heel. Put your shoes on a flat table and view them at eye level from behind. See if the sole is worn evenly. A flat foot will cause more wear on the inside of the sole, especially in the heel area. The shoe will easily rock side to side. A flat foot will also cause the upper part of the shoe to lean inward over the sole. Both shoes should wear about the same way. If you have pain in one foot, you should make sure you don't have a fallen arch on that side. There are two good tests you can perform at home to detect this problem. Place your fingertips on a wall that you are directly facing and stand on your tiptoes on one foot. If you can't do it, a fallen arch may be the culprit. Stand with your feet parallel. Have someone stand in back of you and look at your feet from behind. You can also do it yourself if you stand with your back to a mirror. Normally, only the pinky toe is visible from behind. If one foot is flatter than the other, the 4th and sometimes the 3rd toe on that foot can also be seen.
Non Surgical Treatment
What we want to do is support the arch and maintain it in that curved position. So what you want is to bring the foot into a position where you hold and support the arch so you can get that correct heel-midfoot-big toe contact. You would achieve that with a level of arch support. People will take different levels of support, if you?re somebody who has movement in your arch, a strong level of support will hold and maintain you whereas if you?re someone whose arch has collapsed it could need more support and a level of correction built into the support to realign you. If you think of it, when your arch drops, it affects your foot but it also has a biomechanical effect on the rest of the body. But nothing that can?t be solved.
This is rare and usually only offered if patients have significant abnormalities in their bones or muscles. Treatments include joint fusion, reshaping the bones in the foot, and occasionally moving around tendons in the foot to help balance out the stresses (called tendon transfer).
