There are three types of flat feet: flexible flatfoot, painful rigid flatfoot, and spasmodic flatfoot. Flexible flat feet have some arch, even if the arch only appears while the person is flexing the foot or standing on their toes. Flexible flat feet may not cause pain or require treatment. Painful rigid flatfoot, on the other hand, is abnormal and causes pain, stiffness, and the inability to flex the foot. This often indicates that there is a problem with the bones in the foot, a disease is present, or an injury has occurred. Spasmodic flatfoot involves the foot being forced outward by spasmodic contractions of the peroneal muscle.
There is a lack of normal arch development, probably due to inherent ligamentous laxity. Around 20% of adults have Pes planus. The majority have a flexible flat foot and no symptoms. However, if there is also heel cord contracture, there may be symptoms (see 'Contributing factors', below). Loss of support for the arch. Dysfunction of the tibialis posterior tendon, a common and important cause. Tear of the spring ligament (rare). Tibialis anterior rupture (rare). A neuropathic foot, e.g from diabetes, polio, or other neuropathies. Degenerative changes in foot and ankle joints. Inflammatory arthropathy, eg rheumatoid arthritis. Osteoarthritis. Fractures. Bony abnormalities, eg tarsal coalition.
Fallen arches symptoms may include the following. Being unable to slip fingers underneath arches. Inwards rolling of foot and ankle when running. Knee problems due to lack of support from feet.
You can test yourself to see if you have flat feet or fallen arches by using a simple home experiment. First, dip your feet in water. Then step on a hard flat surface, like a dry floor or a piece of paper on the floor, where your footprints will show. Step away and examine your foot prints. If you see complete/full imprints of your feet on the floor, you may have fallen arches. However, it?s important to seek a second option from a podiatrist if you suspect you have fallen arches so they can properly diagnose and treat you.
Non Surgical Treatment
Heel cord stretching is an important part of treatment, as a tight Achilles tendon tends to pronate the foot. Orthotics (inserts or insoles, often custom-made) may be used. These usually contain a heel wedge to correct calcaneovalgus deformity, and an arch support. This is the usual treatment for flexible Pes Planus (if treatment is needed). A suitable insole can help to correct the deformity while it is worn. Possibly it may prevent progression of flat feet, or may reduce symptoms. However, the effectiveness of arch support insoles is uncertain. Arch supports used without correcting heel cord contracture can make symptoms worse. In patients with fixed Pes planus or arthropathy, customised insoles may relieve symptoms. Reduce contributing factors, wear shoes with low heels and wide toes. Lose weight if appropriate. Do exercises to strengthen foot muscles - walking barefoot (if appropriate), toe curls (flexing toes) and heel raises (standing on tiptoe).
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.
Wear Supportive Footwear. Spend the money it takes to get proper fitting and quality footwear with good arch supports. Most sufferers of fallen arches and plantar fasciitis are born with high arches that sag as they get older. Good footwear can prevent this from becoming a problem. Flat feet, however, can become just as problematic. So, really we should all be wearing good footwear to avoid this potentially painful condition. Take It Easy. If your heel starts to hurt, take a rest. If the pain doesn?t go away after several days of resting, it may be time to see a podiatrist. Orthotics. Special insoles to support the arch of the foot can provide some much needed help. You can buy these at your local drugstore (not recommended), or you can have them specially made and custom fit for your feet. It can take awhile to get just the right one for your foot, but sometimes it can be just what you needed. Weight Control. Yes, maintaining a sensible diet with your ideal weight can be beneficial in many ways. It makes sense to think that the more weight your arches are supporting, the more easily they will fall and become painful.
