Overview

Flat Feet

Over-pronation is very common and affects millions of Australians. To better understand this condition, we'll take a closer look at the 3 most common foot types. An estimated 70% of the population has fallen arches (or a low arch). Only 20% has a normal arch. And 10% have abnormal feet, in other words they either have flat feet or the opposite - a high arched foot.




Causes

Factors that increase your chance of flat feet include family history, diseases that cause muscle or nerve damage, such as peripheral neuropathy, diabetes, cerebral palsy, spina bifida, or muscular dystrophy. Foot injuries. Conditions of the feet that can injure foot tissue such as osteoarthritis. Conditions present at birth, such as excess laxity of joint capsules and ligaments, such as Ehlers-Danlos syndrome. Obesity.




Symptoms

A symptom is something the patient feels and reports, while a sign is something other people, including the doctor may detect. An example of a symptom may be pain in the ankle, while a sign may be a swelling. Symptoms may vary and generally depend on the severity of the condition. Some have an uneven distribution of bodyweight and find that the heel of their shoes wears out more rapidly and more on one side than the other. The most common signs or symptoms of flat feet are pain in the ankle (inner side), there may also be swelling of the foot in general, swelling in the arch of the foot, the calf, knee, the hip, the back, the general lower leg area. People with flat feet may also experience stiffness in one or both feet. One or both feet may be flat on the ground (either no arch, or very slight arch). Shoes may wear unevenly.




Diagnosis

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

Most patients can be treated without surgery using orthotics, supportive shoes and braces. Because of the progressive nature of PTTD, early treatment is advised. If treated early enough, your symptoms may resolve without the need for surgery and progression of your condition can be arrested. In contrast, untreated PTTD could leave you with an extremely flat foot, painful arthritis in the foot and ankle, and increasing limitations on walking, running, or other activities.




Surgical Treatment

Flat Feet

Generally one of the following procedures is used to surgically repair a flat foot or fallen arch. Arthrodesis. One or more of your bones in the foot or ankle are fused together. Osteotomy. Correcting alignment by cutting and reshaping a bone. Excision. Removing a bone or a bone spur. Synovectomy. Cleaning the sheath that covers the tendon. Tendon transfer. Using a piece of one tendon to lengthen or replace another. Arthroereisis. placing a small device in the subtalar joint to limit motion. For most people, treatment is successful, regardless of the cause, although the cause does does play a major role in determining your prognosis. Some causes do not need treatment, while others require a surgical fix.




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.
