Dealing With Feet Dilemmas

Fallen Arches Causes And Symptoms

Overview

Flat Feet

Some people have always had flat feet from a young age. Unfortunately as people reach their fifties they will suddenly have one foot with a flatter arch than the other foot. This situation is termed adult acquired flatfoot. Adult acquired flatfoot is a painful condition occurring in one foot. The common patient profile is a female over the age of 50 with pre-existing flatfeet, high blood pressure, high cholesterol, diabetes and obesity. All of these underlying problems will lead to a weakening of the support structures of the arch. If you have adult acquired flat foot you will not be able to lift your heel off the ground while standing on one leg. Adult acquired flatfoot may develop due to trauma or degeneration of major tendons ankle & foot. Weakness or paralysis of leg muscles can also create a flatfoot deformity. Adult acquired flat foot can be treated with physical therapies, motion control running shoes or hiking boots, custom foot orthoses, and ankle foot orthoses.

Causes

Some people develop fallen arches because they tend to pronate, or roll inwards on the ankles, says the Instep Foot Clinic. Other people may simply have under-developed muscles in their arches. Your arches help your feet bear weight and are supported in this job by muscles and tendons in your feet and ankles. So, while fallen arches aren?t usually serious, they can cause pain in your feet, ankles, knees and/or hips due to your reduced weight-bearing ability. In these cases, treatment may be required. Orthotics that sit in your shoes and support your arches are a common solution, as are exercises to strengthen and stretch your feet and leg muscles.

Symptoms

Symptoms that should be checked by a pediatrician include foot pain, sores or pressure areas on the inner side of the foot, a stiff foot, limited side-to-side foot motion, or limited up-and-down ankle motion. For further treatment you should see a pediatric orthopedic surgeon or podiatrist experienced in childhood foot conditions.

Diagnosis

If you notice that your feet are flat, but you?re not really experiencing any pain, then you?re probably okay to go without a visit to the podiatrist (unless, of course, you have a lack of feeling in your foot). You can schedule a hair appointment instead, or maybe see a movie. However, once painful symptoms start to appear, it?s better to skip the hirsute (or cinematic) experience and go see your foot doctor. Your podiatrist will likely make the diagnosis by examining your foot visually, asking about symptoms you may be experiencing, and may test your muscle strength. You may be asked to stand on your toes (in a ballerina pose, if you prefer, although that?s certainly not required), or walk around the examining room, and you may need to show the podiatrist your shoes. He or she may comment on your excellent taste in footwear, but is more likely to check your shoes for signs of wear that may indicate fallen arches. Your podiatrist may recommend X-rays, a CT scan or an MRI in order to get a look at the interior of your foot, although the best diagnosis usually comes from the doctor?s own in-person examination.

Non Surgical Treatment

Some of the aspects of the pain with a ?fallen arch? are related to the crushing of the joints of the outside of the foot and from the stretching of ligaments and tendons of the inside of the foot. Unfortunately, some parts of the damage from the fallen arch, the weakness in the tendons and the new shape of the foot, are not correctable without surgical reconstruction. The first goal is to stabilize the collapsed arch. This can be done through braces. If the deformity is mild, an over-the-counter arch support may be sufficient. In more severe deformities an hinged or solid ankle brace may be necessary. Rehabilitative exercises under the supervision of a physical therapist will help increase the strength of the remaining muscles. Stiffness of certain tendons including the Achilles and hamstring is also very helpful as tightness in these structures is very common in people with ?fallen arches?. Postural training is necessary. A short period of casting or walking in a cast boot will improve swelling of a recent partial tear of the tendons and ligaments on the inside of the ankle. Nonsteroidal anti-inflammatory medications such as ibuprofen, and naprosyn can help to relieve the pain, but do not heal the injuries associated with this or decrease the swelling significantly. Surgical reconstruction is available if the pain cannot be controlled reasonably with these measures.

Surgical Treatment

Acquired Flat Feet

Surgical correction is dependent on the severity of symptoms and the stage of deformity. The goals of surgery are to create a more functional and stable foot. There are multiple procedures available to the surgeon and it may take several to correct a flatfoot deformity. Stage one deformities usually respond to conservative or non-surgical therapy such as anti-inflammatory medication, casting, functional orthotics or a foot ankle orthosis called a Richie Brace. If these modalities are unsuccessful surgery is warranted. Usually surgical treatment begins with removal of inflammatory tissue and repair of the posterior tibial tendon. A tendon transfer is performed if the posterior tibial muscle is weak or the tendon is badly damaged. The most commonly used tendon is the flexor digitorum longus tendon. This tendon flexes or moves the lesser toes downward. The flexor digitorum longus tendon is utilized due to its close proximity to the posterior tibial tendon and because there are minimal side effects with its loss. The remainder of the tendon is sutured to the flexor hallucis longus tendon that flexes the big toe so that little function is loss. Stage two deformities are less responsive to conservative therapies that can be effective in mild deformities. Bone procedures are necessary at this stage in order to recreate the arch and stabilize the foot. These procedures include isolated fusion procedures, bone grafts, and/or the repositioning of bones through cuts called osteotomies. The realigned bones are generally held in place with screws, pins, plates, or staples while the bone heals. A tendon transfer may or may not be utilized depending on the condition of the posterior tibial tendon. Stage three deformities are better treated with surgical correction, in healthy patients. Patients that are unable to tolerate surgery or the prolonged healing period are better served with either arch supports known as orthotics or bracing such as the Richie Brace. Surgical correction at this stage usually requires fusion procedures such as a triple or double arthrodesis. This involves fusing the two or three major bones in the back of the foot together with screws or pins. The most common joints fused together are the subtalar joint, talonavicular joint, and the calcaneocuboid joint. By fusing the bones together the surgeon is able to correct structural deformity and alleviate arthritic pain. Tendon transfer procedures are usually not beneficial at this stage. Stage four deformities are treated similarly but with the addition of fusing the ankle joint.

After Care

Time off work depends on the type of work as well as the surgical procedures performed. . A patient will be required to be non-weight bearing in a cast or splint and use crutches for four to twelve weeks. Usually a patient can return to work in one to two weeks if they are able to work while seated. If a person's job requires standing and walking, return to work may take several weeks. Complete recovery may take six months to a full year. Complications can occur as with all surgeries, but are minimized by strictly following your surgeon's post-operative instructions. The main complications include infection, bone that is slow to heal or does not heal, progression or reoccurrence of deformity, a stiff foot, and the need for further surgery. Many of the above complications can be avoided by only putting weight on the operative foot when allowed by your surgeon.
