Solving Foot Ailments

What Is Pes Planus?

Overview

Flat Foot

Most of us have a low arch. The foot actually appears quite normal and a clear (but low) arch is present under the foot, especially when sitting down. The situation changes with weight bearing: when we get up the arch lowers. When we start walking the arches collapse and the ankles roll inwards. This is called over-pronation - or fallen arches. Over-pronation is not the same as flat feet as often noted. Pronation itself is not wrong as we need to pronate and supinate as part of our gait. Pronation (rolling in) acts as a shock absorbing process and supination (rolling out) helps to propel our feet forward.

Causes

Aging, injury, overuse, or illness can result in fallen arches or a fallen arch on one side. Diabetes. Obesity. Pregnancy. Nerve conditions. Foot abnormalities present since birth. Broken or dislocated bones in the foot. Stretched or torn tendons. Medical conditions such as arthritis. Sudden weight gain

Symptoms

People will have a very heavily dropped arch and it won?t affect them at all and people will have it slightly dropped and it could cause fierce problems. It could cause things like plantar fasciitis, it could cause heel spurs, desperate ball-of-the-foot pressure, or pressure on the big toe known as the hallux which causes discomfort in the foot. It will create problems upwards to the knees, hips and the back once you?re out of line.

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

There are different modalities of treatment that are available to manage flat feet and fallen arches. The type of treatment that is chosen depends upon how severe the condition is and what symptoms the patients are experiencing. Below is a brief description of the available treatment modalities. In the event that the patient is experiencing swelling of the feet, rest and ice application is usually the initial treatment step. Oral anti-inflammatories may be offered which can help reduce inflammation as well as associated pain. Physical therapy has good outcomes and can include different exercises such as stretches and strengthening of the surrounding muscles. Changes in footwear and activity modification are also important when dealing with a painful flat (pronated) foot. These days, orthotic insoles are easily available either over the counter or through your Podiatrist which can effectively help maintain the arch of the foot and reduce the amount of stress placed on the foot. Podiatrists are able to prescribe a variety of different devices from prefabricated to customized and are trained to determine the most appropriate device for each individual. In order to offer the right kind of orthotic insole, podiatrists may perform a test called gait analysis. This involves asking the patient to walk and videoing the different movements that the foot of forms during the walking. Features such as over pronation can be easily seen on this and orthotic insoles can be prescribed to correct the specific abnormalities that are picked up on this analysis. Overall, orthotic treatment can result in a significant improvement in foot movement and reduction in foot discomfort.

Surgical Treatment

Acquired Flat Foot

This is rare and usually only offered if patients have significant abnormalities in their bones or muscles. Treatments include joint fusion, reshaping the bones in the foot, and occasionally moving around tendons in the foot to help balance out the stresses (called tendon transfer).

Prevention

Going barefoot, particularly over terrain such as a beach where muscles are given a good workout, is good for all but the most extremely flatfooted, or those with certain related conditions such as plantar fasciitis. Ligament laxity is also among the factors known to be associated with flat feet. One medical study in India with a large sample size of children who had grown up wearing shoes and others going barefoot found that the longitudinal arches of the bare footers were generally strongest and highest as a group, and that flat feet were less common in children who had grown up wearing sandals or slippers than among those who had worn closed-toe shoes. Focusing on the influence of footwear on the prevalence of pes planus, the cross-sectional study performed on children noted that wearing shoes throughout early childhood can be detrimental to the development of a normal or a high medial longitudinal arch. The vulnerability for flat foot among shoe-wearing children increases if the child has an associated ligament laxity condition. The results of the study suggest that children be encouraged to play barefooted on various surfaces of terrain and that slippers and sandals are less harmful compared to closed-toe shoes. It appeared that closed-toe shoes greatly inhibited the development of the arch of the foot more so than slippers or sandals. This conclusion may be a result of the notion that intrinsic muscle activity of the arch is required to prevent slippers and sandals from falling off the child?s foot.

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.
