A variety of foot problems can lead to adult acquired flatfoot deformity (AAFD), a condition that results in a fallen arch with the foot pointed outward. Most people - no matter what the cause of their flatfoot - can be helped with orthotics and braces. In patients who have tried orthotics and braces without any relief, surgery can be a very effective way to help with the pain and deformity. This article provides a brief overview of the problems that can result in AAFD. Further details regarding the most common conditions that cause an acquired flatfoot and their treatment options are provided in separate articles. Links to those articles are provided.
Footwear: shoes which limit toe movement; high heels. Barefoot walking may be protective. A tight Achilles tendon or calf muscles (heel cord contracture). This may help to cause Pes Planus, or may contribute to symptoms such as foot pain when there is existing Pes Planus. Obesity. Other bony abnormalities, eg rotational deformities, tibial abnormalities, coalition (fusion) of tarsal bones, equinus deformity. Ligamentous laxity, eg familial, Marfan's syndrome, Ehlers-Danlos syndrome, Down's syndrome. Other factors causing foot pronation, eg hip abductor weakness and genu valgum.
Having flat feet can be painless and is actually normal in some people. But others with flat feet experience pain in the heel or arch area, difficulty standing on tiptoe, or have swelling along the inside of the ankle. They may also experience pain after standing for long periods of time or playing sports. Some back problems can also be attributed to flat feet.
There are a few simple ways to assess your foot type, and most include making an imprint of your footprint. The classic way is to stand on a hard floor surface with wet feet to make a wet foot print. Look at the narrowest part of your footprint, which should be between your heel and ball of your foot. If the print of your foot in this part is less than 10% of the width of the widest part then you are likely to have high arches. more than 10% but less than 25% then your foot profile is probably normal, more than 25% or even the widest part, then you have flat feet.
Is flat footedness genetic?
Non Surgical Treatment
Some of the aspects of the pain with a ?fallen arch? are related to the crushing of the joints of the outside of the foot and from the stretching of ligaments and tendons of the inside of the foot. Unfortunately, some parts of the damage from the fallen arch, the weakness in the tendons and the new shape of the foot, are not correctable without surgical reconstruction. The first goal is to stabilize the collapsed arch. This can be done through braces. If the deformity is mild, an over-the-counter arch support may be sufficient. In more severe deformities an hinged or solid ankle brace may be necessary. Rehabilitative exercises under the supervision of a physical therapist will help increase the strength of the remaining muscles. Stiffness of certain tendons including the Achilles and hamstring is also very helpful as tightness in these structures is very common in people with ?fallen arches?. Postural training is necessary. A short period of casting or walking in a cast boot will improve swelling of a recent partial tear of the tendons and ligaments on the inside of the ankle. Nonsteroidal anti-inflammatory medications such as ibuprofen, and naprosyn can help to relieve the pain, but do not heal the injuries associated with this or decrease the swelling significantly. Surgical reconstruction is available if the pain cannot be controlled reasonably with these measures.
Fallen arches may occur with deformities of the foot bones. Tarsal coalition is a congenital condition in which the bones of the foot do not separate from one another during development in the womb. A child with tarsal coalition exhibits a rigid flat foot, which can be painful, notes the patient information website eOrthopod. Surgery may prove necessary to separate the bones. Other foot and ankle conditions that cause fallen arches may also require surgery if noninvasive treatments fail to alleviate pain and restore normal function.
