What Are Fallen Arches

Overview

Acquired Flat Foot

?Pes Planus? is the medical term for flat feet. It comes from Latin: Pes = foot and Planus = plain, level ground. Very few people suffer from this condition, as a true flat foot is very rare. Less than 5% of the population has flat feet. The majority of the Australian population, however, has fallen arches (an estimated 60-70% of the population) known in the medical profession as ?excess pronation? or over-pronation. Over-pronation means the foot and ankle tend to roll inwards and the arch collapses with weight-bearing. This is a quite a destructive position for the foot to function in and may cause a wide variety of foot, leg and lower back conditions.

Causes

There are several factors that can contribute to the development of fallen arches. These factors include the following. Genetic abnormality, torn or stretched tendons, amage to the posterior tibial tendon, bone fractures, dislocation of bones, nerve damage, rheumatoid arthritis and other medical conditions. In addition, there are other factors that can increase your risk of developing fallen arches. These risk factors include diabetes, pregnancy, Obesity and Aging.

Symptoms

Fallen arches may induce pain in the heel, the inside of the arch, the ankle, and may even extend up the body into the leg (shin splints), knee, lower back and hip. You may also experience inflammation (swelling, redness, heat and pain) along the inside of the ankle (along the posterior tibial tendon). Additionally, you may notice some changes in the way your foot looks. Your ankle may begin to turn inward (pronate), causing the bottom of your heel to tilt outward. Other secondary symptoms may also show up as the condition progresses, such as hammertoes or bunions. You may also want to check your footprint after you step out of the shower. (It helps if you pretend you?re in a mystery novel, and you?re leaving wet, footprinty clues that will help crack the case.) Normally, you can see a clear imprint of the front of your foot (the ball and the toes) the heel, and the outside edge of your foot. There should be a gap (i.e. no footprinting) along the inside where your arches are. If your foot is flat, it?ll probably leave an imprint of the full bottom of your foot-no gap to be had. Your shoes may also be affected: because the ankle tilts somewhat with this condition, the heel of your shoes may become more worn on one side than another.

Diagnosis

People who have flat feet without signs or symptoms that bother them do not generally have to see a doctor or podiatrist about them. However, if any of the following occur, you should see your GP or a podiatrist. The fallen arches (flat feet) have developed recently. You experience pain in your feet, ankles or lower limbs. Your unpleasant symptoms do not improve with supportive, well-fitted shoes. Either or both feet are becoming flatter. Your feet feel rigid (stiff). Your feet feel heavy and unwieldy. Most qualified health care professionals can diagnose flat feet just by watching the patient stand, walk and examining his/her feet. A doctor will also look at the patient's medical history. The feet will be observed from the front and back. The patient may be asked to stand on tip-toe while the doctor examines the shape and functioning of each foot. In some cases the physician may order an X-ray, CT (computed tomography) scan, or MRI (magnetic resonance imaging) scan.

Why do arches fall?

Non Surgical Treatment

The typical treatment for pain from fallen arches is an arch insert. While many people experience dramatic pain relief from this, others continue to suffer from chronic achy feet despite the arch support. The problem with this approach is that it does not do anything to strengthen the weak ligaments that may be at the root of the problem and, thus, does not alleviate the chronic pain that people with this condition experience. Another standard practice of modern medicine is to use steroids or to prescribe anti-inflammatory medications. However, in the long run, these treatments do more damage than good. Cortisone shots and anti-inflammatory drugs have been shown to produce short-term pain benefit, but both result in long-term loss of function and even more chronic pain by actually inhibiting the healing process of soft tissues and accelerating cartilage degeneration. Plus, long-term use of these drugs can lead to other sources of chronic pain, allergies and leaky gut syndrome.

Surgical Treatment

Adult Acquired Flat Feet

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).

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.
