Are Fallen Arches Flat Feet?

Overview

Adult Acquired Flat Foot

The terms fallen arches and flat feet are used interchangeably to refer to a condition in which there is no arch of the foot. An arch is formed by tendons in the foot that stretch from the heel of the foot to the base of the toes, or metatarsals. There are also supporting tendons that originate in the lower leg. Together, these tendons work to form an arch, noticeable as a slight rise in the inner midsole of the foot. This rise or arch can be classified as a normal arch, a high arch, or a fallen arch. When tendons do not work together to pull properly, this results in a fallen arch or flat foot. Aside from the occasional pain associated with flat feet, problems with fallen arches can extend upwards to the ankles, knees, hips, and even the back, altering the biomechanics of the body.

Causes

Flat feet are often a congenital problem which has no specific cause. They can however occur after an injury, especially conditions such as Tibialis Posterior Syndrome or more traumatic injuries such as fractures or mid-tarsal joint sprains. The other thing to look out for is Overpronation. Often this is confused with having flat feet (or a fallen arch) although it is not technically the same thing. If an individual does not have flat feet but does overpronate then the arch of their foot appears to be normal when standing. However, when they walk the arch collapses and the foot rolls in excessively. This is more difficult to spot than flat feet. It is estimated that between 60 and 80% of the population overpronate!

Symptoms

Depending on the cause of the flatfoot, a patient may experience one or more of the different symptoms below. Pain along the course of the posterior tibial tendon which lies on the inside of the foot and ankle. This can be associated with swelling on the inside of the ankle. Pain that is worse with activity. High intensity or impact activities, such as running, can be very difficult. Some patients can have difficulty walking or even standing for long periods of time. When the foot collapses, the heel bone may shift position and put pressure on the outside ankle bone (fibula). This can cause pain on the outside of the ankle. Arthritis in the heel also causes this same type of pain. Patients with an old injury or arthritis in the middle of the foot can have painful, bony bumps on the top and inside of the foot. These make shoewear very difficult. Occasionally, the bony spurs are so large that they pinch the nerves which can result in numbness and tingling on the top of the foot and into the toes. Diabetics may only notice swelling or a large bump on the bottom of the foot. Because their sensation is affected, people with diabetes may not have any pain. The large bump can cause skin problems and an ulcer (a sore that does not heal) may develop if proper diabetic shoewear is not used.

Diagnosis

It is important for people with foot pain to know if they have flat feet. The following tests can help you determine your arch type. When you get out of a swimming pool, look at your footprint on the concrete. The front of the foot will be joined to the heel by a strip. If your foot is flat, then the strip is the same width as the front of the foot, creating a footprint that looks like a stretched out pancake. With a normal arch, the strip is about half the width of the front of the foot. If you have a high arch, only a thin strip connects the front of the foot with the heel. Put your shoes on a flat table and view them at eye level from behind. See if the sole is worn evenly. A flat foot will cause more wear on the inside of the sole, especially in the heel area. The shoe will easily rock side to side. A flat foot will also cause the upper part of the shoe to lean inward over the sole. Both shoes should wear about the same way. If you have pain in one foot, you should make sure you don't have a fallen arch on that side. There are two good tests you can perform at home to detect this problem. Place your fingertips on a wall that you are directly facing and stand on your tiptoes on one foot. If you can't do it, a fallen arch may be the culprit. Stand with your feet parallel. Have someone stand in back of you and look at your feet from behind. You can also do it yourself if you stand with your back to a mirror. Normally, only the pinky toe is visible from behind. If one foot is flatter than the other, the 4th and sometimes the 3rd toe on that foot can also be seen.

Non Surgical Treatment

If you have fallen arches, but you are not experiencing any symptoms, then you probably do not need to seek treatment. If you are experiencing discomfort due to fallen arches, there are several treatment options. These treatment options include elevating the feet and applying ice to ease discomfort and reduce swelling, rest, exercises to stretch the feet, physical therapy, medication, such as anti-inflammatories, steroid injections and orthotic devices or customised arch supportsto wear in the shoes. If you have fallen arches and periodically experience pain related to that condition, it is a good idea to get orthotic devicesor custom arch supports, to wear in your shoes. The other treatment options, like medication and ice, will help to ease pain from fallen arches after you have already begun to experience pain. However, orthotic devices or(custom arch supports)can help to prevent pain from occurring at all. This preventative measure helps many people with fallen arches to avoid pain and prevent worsening of their condition. In severe cases of fallen arches, surgery may be required to correct the problem. You can also help to prevent pain and exacerbation of fallen arches by reducing your risk factors. If you are overweight, try to lose weight. Even a small weight loss can reduce the pressure on your feet significantly. If you are diabetic, manage your blood sugar as best as possible. Losing weight often also improves the condition of diabetics. You should also avoid high-impact activities, like running on the road, tennis, and sports that involve jumping. Try a gentler form of exercise, like swimming, instead. If you have fallen arches, orthotic devices or(custom arch supports)are an important component of your treatment and can help to prevent pain.

Surgical Treatment

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). 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.

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.
