Flat Feet

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.




Causes

A Rigid Flat Foot may be congenital, where the arch never develops when growing. A Rigid Flat Foot can also be acquired due to disease processes involving inflammatory arthritis, neurological conditions such as Charcot neuro-arthropathy or trauma. A Flexible Flat Foot (fallen arches) may also be congenital where excessive pronation occurs for shock absorption. In some cases this condition may be the result of neurological disease or injury involving muscle weakness, hyper-mobile joints or ligament laxity. These conditions may allow for excessive pronation causing the arch to fall when weight bearing or during activity. Both of these foot types can result in posture mal-alignment involving the lower back, hips, knees and feet which may result in pain in those areas.




Symptoms

Pain and stiffness of the medial arch or anywhere along the mid-portion of the foot. Associated discomfort within and near the ankle joint. The knees, hips, and lower back may be the primary source of discomfort. Feet may often feel tired and achy. Painful shin splints may develop with activity. Gait may be awkward.




Diagnosis

Your doctor examines your feet to determine two things, whether you have flat feet and the cause or causes. An exam may include the following steps, Checking your health history for evidence of illnesses or injuries that could be linked to flat feet or fallen arches, Looking at the soles of your shoes for unusual wear patterns, Observing the feet and legs as you stand and do simple movements, such as raising up on your toes, Testing the strength of muscles and tendons, including other tendons in the feet and legs, such as the Achilles tendon or the posterior tibial tendon, Taking X-rays or an MRI of your feet.




Non Surgical Treatment

Treatment often consists of giving the affected foot support from underneath so that the strain is taken off it (by the use of insoles or support pads) and so symptoms are relieved. A specialist in this problem is known as a podiatrist and these do work in the NHS - ask you father's doctor whether his condition is bad enough to warrant a referral to such a specialist.




Surgical Treatment

Acquired Flat Foot

Surgical procedures for flat feet vary depending on the root cause of the condition. Surgical correction to control pronation may include bone implants or Achilles tendon lengthening. Tendon transfer, which is a procedure to re-attach a tendon to another area of bone, may also be used to reduce pronation and improve foot function.




Prevention

Well-fitted shoes with good arch support may help prevent flat feet. Maintaining a healthy weight may also lower wear and tear on the arches.
