Overview
The human foot is a complex structure that absorbs shock every time we take a step. The foot has to adapt to a variety of movements during different forms of activities such as walking, running and climbing steps. The foot is made up of many different joints, ligaments and muscles which have to work together to allow us to move and balance. The arch of the foot plays and important role in absorbing shock and preventing over stressing of the foot muscles and bones. In this article, we shall briefly discuss flat feet and fallen arches. These two conditions are closely related to each other and can increase the risk of overuse injury to the foot. They can also cause overload of more proximal structures such as ankles, shins, knees and the lower back.
Causes
When flat feet develop at a later age, they are known as fallen arches. The arches may fall because the muscles supporting them are no longer able to do so. In addition the spring ligament within the foot may have lost some of its tension allowing the arch of the foot to flatten. Other conditions causing fallen arches include sudden weight gain, a nervous system injury, or a loss of sensation caused by a disease such as diabetes. Most people with fallen arches are flat on both feet.
Symptoms
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
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.
Non Surgical Treatment
When pain results from a fallen arch, the physician may prescribe these. Rest and ice. A brace to help support the fallen arch. Physical therapy to strengthen and stretch the foot. Orthotics (arch supports) to compensate for a fallen arch. The physician may tell the patient to choose shoes that have proper arch supports and avoid non-supportive shoes such as flip-flops. If obesity contributed to the fallen arch, the patient should lose weight.
Surgical Treatment
Procedures may include the following. Fusing foot or ankle bones together (arthrodesis). Removing bones or bony growths, also called spurs (excision). Cutting or changing the shape of the bone (osteotomy). Cleaning the tendons' protective coverings (synovectomy). Adding tendon from other parts of your body to tendons in your foot to help balance the "pull" of the tendons and form an arch (tendon transfer). Grafting bone to your foot to make the arch rise more naturally (lateral column lengthening).
Prevention
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.
After Care
Patients may go home the day of surgery or they may require an overnight hospital stay. The leg will be placed in a splint or cast and should be kept elevated for the first two weeks. At that point, sutures are removed. A new cast or a removable boot is then placed. It is important that patients do not put any weight on the corrected foot for six to eight weeks following the operation. Patients may begin bearing weight at eight weeks and usually progress to full weightbearing by 10 to 12 weeks. For some patients, weightbearing requires additional time. After 12 weeks, patients commonly can transition to wearing a shoe. Inserts and ankle braces are often used. Physical therapy may be recommended. There are complications that relate to surgery in general. These include the risks associated with anesthesia, infection, damage to nerves and blood vessels, and bleeding or blood clots. Complications following flatfoot surgery may include wound breakdown or non-union (incomplete healing of the bones). These complications often can be prevented with proper wound care and rehabilitation. Occasionally, patients may notice some discomfort due to prominent hardware. Removal of hardware can be done at a later time if this is an issue. The overall complication rates for flatfoot surgery are low.
