Managing Fallen Arches

Overview

Acquired Flat Foot

Flat feet and fallen arches are common conditions that are in most cases asymptomatic. However, in patients who do have symptoms, treatments are available that can help reduce pain and promote efficient movement. Orthotic devices are well recognised as an excellent treatment and podiatrists can offer these different treatment modalities as individualised treatments for patients.

Causes

Most cases of flatfeet are simply the result of normal development. When that is not the case, the condition can be caused by a number of factors, including the following, Age, disease, injury, obesity or being overweight, physical abnormality, pregnancy. Flattened arches in adults may result from the stresses of aging, weight gain, and the temporary increase in elastin (protein in connective tissue) due to pregnancy. In some cases, flatfeet are caused by a physical abnormality, such as tarsal coalition (two or more bones in the foot that have grown together) or accessory navicular (an extra bone along the side of the foot). The effects of diseases such as diabetes and rheumatoid arthritis can lead to flatfeet. An injury (e.g., bone fracture, dislocation, sprain or tear in any of the tendons and ligaments in the foot and leg) also can cause flatfeet.

Symptoms

Some people have fallen arches, and they aren?t even aware of it, fallen arches are sometimes asymptomatic and do not always cause pain. However, for others, the following symptoms may be present. Foot pain, particularly in the arches or heels, leg or back pain, feet feel tired quickly, swelling in the feet and difficulty moving the feet.

Diagnosis

Your doctor examines your feet to determine two things, whether you have flat feet and the cause or causes. An exam may include the following steps, Checking your health history for evidence of illnesses or injuries that could be linked to flat feet or fallen arches, Looking at the soles of your shoes for unusual wear patterns, Observing the feet and legs as you stand and do simple movements, such as raising up on your toes, Testing the strength of muscles and tendons, including other tendons in the feet and legs, such as the Achilles tendon or the posterior tibial tendon, Taking X-rays or an MRI of your feet.

Is flat footedness genetic?

Non Surgical Treatment

Flexible flat feet that are painless do not require treatment. If you have pain due to flexible flat feet, an orthotic (arch-supporting insert in the shoe) can bring relief. With the increased interest in running, many shoe stores carry shoes for normal feet and pronated feet. The shoes designed for pronated feet make long distance running easier and less tiring because they correct for the abnormality. Rigid or painful flat feet require evaluation by a podiatrist. The treatment depends on the cause of the flat feet. For tarsal coalition, treatment starts with rest and possibly a cast. If this fails to improve the pain, surgery may be necessary. For problems with the posterior tibial tendon, treatment may start with rest, anti-inflammatory medications, and shoe inserts or ankle braces. In more advanced cases, surgery may be needed to clean or repair the tendon, or fuse some of the joints of the foot into a corrected position. Flat feet in older adults can be treated with pain relievers, orthotics, and sometimes surgery.

Surgical Treatment

Adult Acquired Flat Feet

Surgery is typically offered as a last resort in people with significant pain that is resistant to other therapies. The treatment of a rigid flatfoot depends on its cause. Congenital vertical talus. Your doctor may suggest a trial of serial casting. The foot is placed in a cast and the cast is changed frequently to reposition the foot gradually. However, this generally has a low success rate. Most people ultimately need surgery to correct the problem. Tarsal coalition. Treatment depends on your age, extent of bone fusion and severity of symptoms. For milder cases, your doctor may recommend nonsurgical treatment with shoe inserts, wrapping of the foot with supportive straps or temporarily immobilizing the foot in a cast. For more severe cases, surgery is necessary to relieve pain and improve the flexibility of the foot. Lateral subtalar dislocation. The goal is to move the dislocated bone back into place as soon as possible. If there is no open wound, the doctor may push the bone back into proper alignment without making an incision. Anesthesia is usually given before this treatment. Once this is accomplished, a short leg cast must be worn for about four weeks to help stabilize the joint permanently. About 15% to 20% of people with lateral subtalar dislocation must be treated with surgery to reposition the dislocated bone.

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.
