What Are Fallen Arches

Overview

Adult Acquired Flat Foot

Also sometimes called "fallen arches", the condition of flat feet is characterized by a lack of appropriate arch in the inner foot. It can be a genetic condition or the result of improper body mechanics. Often the whole of the foot will contact the ground with little to no arch being present. Because a normal foot is structurally able to support the weight of the body thanks to the bone structure that comprises the arch, a flat foot often is unable to properly support this weight and will cause extreme pressure in the joints in the foot and above, such as the ankles, knees and hips. Other problems such as tendonitis, bunion and hammertoe deformities, arthritis of the foot joints, and chronic fatigue of the leg muscles can also result.

Causes

Fallen arches have many causes. If you have fallen arches, or flat feet, the normal arch in the middle of your foot is not curved properly. You can have this condition called ples planus in medical terms and never have any symptoms. However, fallen arches can lead to foot pain, fatigue or more serious conditions. If fallen arches alter the way you walk, you may eventually develop knee, hip and low back pain. Your foot may lose normal range of motion making it hard to rise up onto your toes. In some cases, your feet can become swollen. If you have this condition, talk to your doctor about an appropriate treatment plan.

Symptoms

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.

Diagnosis

Many medical professionals can diagnose a flat foot by examining the patient standing or just looking at them. On going up onto tip toe the deformity will correct when this is a flexible flat foot in a child with lax joints. Such correction is not seen in the adult with a rigid flat foot. An easy and traditional home diagnosis is the "wet footprint" test, performed by wetting the feet in water and then standing on a smooth, level surface such as smooth concrete or thin cardboard or heavy paper. Usually, the more the sole of the foot that makes contact (leaves a footprint), the flatter the foot. In more extreme cases, known as a kinked flatfoot, the entire inner edge of the footprint may actually bulge outward, where in a normal to high arch this part of the sole of the foot does not make contact with the ground at all.

Non Surgical Treatment

Custom orthotics are specially designed insoles, which are made for your by prescription. This is done by taking a plaster cast of the foot in its neutral position and is then sent to a laboratory, with your prescription to be made to your exact specifications. The insole then correctly aligns your foot and as a result your body. This will relieve abnormal strain of tissues and structures which can cause pain. For less severe mal-alignments or for sports use a wide variety of temporary insoles.

Surgical Treatment

Acquired Flat Foot

In cases of flat feet that have progressed substantially or have failed to improve with non-surgical treatment, surgery may be required and in some advanced cases, surgery may be the only option. Your foot and ankle surgeon will determine the best approach for you.

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 nonunion (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.
