The branch of medicine that is focused on the treatment, diagnosis, and study of disorders of the lower leg, ankle and foot is referred to as podiatry. Because people often spend a great deal of their time on their feet, many problems in this area can occur. A person seeks help from the field of podiatry when they need treatment for heel spurs, bunions, arch problems, deformities, ingrown toenails, corns, foot and ankle problems, infections, and problems with the foot that are related to diabetes and additional diseases.

To treat problems of the foot, ankle or lower leg, a podiatrist may prescribe physical therapy, drugs, perform surgery, or set fractures. Individuals may also be recommended to wear corrective shoe inserts, custom-made shoes, plaster casts and strappings in order to correct deformities.

When trying to gather information on a patient problem, a scanner or force plate may be used in order to design orthotics. During this procedure, patients are told to walk across a plate that is connected to a computer; the computer then takes a scan of the foot and indicates weight distribution and pressure points. The computer readouts will give the podiatrist information to help them determine the correct treatment plans.

Diagnosis is also provided through laboratory tests and x-rays. Through the foot, the first signs of serious problems such as heart disease, diabetes and arthritis can show up. For example, individuals that have diabetes may frequently have problems such as infections and foot ulcers because they experience poor circulation in the foot area. A podiatrist can then have consultations with patients when symptoms arise. Referrals will then be made to specialists that handle the greater health problems.

Some podiatrists have their own independent, private practices or clinics where they have a small staff and administrative personnel. Many podiatrists work within group practices. They usually spend time performing surgery in ambulatory surgical centers or hospitals, or visit patients in nursing homes. Podiatrists typically spend between 30 to 60 hours of week working. Some podiatrists specialize in public health, orthopedics, surgery, or primary care. Other fields include specialties in geriatrics, dermatology, pediatrics, diabetic foot care and sports medicine.

Some podiatrist specialists complete extra training in the area of foot and ankle reconstruction that results from the effects of physical trauma or diabetes. There are also surgeons that perform surgery of a cosmetic nature to correct bunions and hammertoes.

Athlete’s foot, or tinea pedis, is a skin disease caused by a fungal infection.  The infection typically occurs between the toes, and the feet are most subject to this disease because shoes best create the warm, dark, and moist environment in which fungus thrives.  Other areas that create a similar environment, such as swimming pools, public showers, and locker rooms; can also promote fungi growth. 

Symptoms of athlete’s foot include dry skin, itching, scaling, inflammation, and blistering.  Sometimes, blisters can evolve into the cracks or breaks in the skin.  The exposed tissue can then create pain, swelling, and discharge.  The spread of infection can cause itching and burning as well.

While athlete’s foot commonly occurs between the toes, it may also spread to the toenails or soles of the feet.  Other parts of the body, such as the groin or underarms, can also become infected if they are touched after the original area of infection is scratched.  Aside from physical contact, athlete’s foot can also spread through the contamination of footwear, clothing or bedsheets.

Proper foot hygiene is essential in preventing athlete’s foot.  You can prevent the fungus from spreading by frequently washing your feet using soap and water, thoroughly drying the feet between the toes, changing shoes and socks every day to reduce moisture, and ensuring that bathroom and shower floors are disinfected.  Other tips include using shower shoes, avoiding walking barefoot in public environments, wearing light and airy shoes, and wearing socks that keep the feet dry.

While treatment for athlete’s foot can involve topical or oral antifungal drugs, mild cases of the infection can be treated by dusting foot powder in shoes and socks.  Any treatment used can be supplemented by frequently bathing the feet and drying the toes.  If proper foot hygiene and self-care do not ease your case of athlete’s foot, contact your podiatrist.  He will determine if the underlying cause of your condition is truly a fungus.  If that is the case, a comprehensive treatment plan may be suggested with the inclusion of prescription antifungal medications.

Flatfoot is a foot disorder that is not as straightforward as many people believe.  Various types of flatfoot exist, each with their own varying deformities and symptoms.  The partial or total collapse of the arch, however, is a characteristic common to all types of flatfoot.  Other signs of flatfoot include:

• “Toe drift,” or the pointing outward of the toes and the front part of the foot
• The tilting outward of the heel and the tilting inward of the ankle
• The lifting of the heel off the ground earlier when walking due to a tight Achilles tendon
• Hammertoes
• Bunions

One of the most common types of flatfoot is flexible flatfoot.  This variation usually starts in childhood and progresses as one ages into adulthood.  Flexible flatfoot presents as a foot that is flat when standing, or weight-bearing.  When not standing, the arch returns.  Symptoms of flexible flatfoot include:

• Pain located in the heel, arch, ankle, or along the outside of the foot
• Overpronation, or an ankle that rolls in
• Shin splint, or pain along the shin bone
• General foot aches or fatigue
• Pain located in the lower back, hip, or knee

Your podiatrist will most likely diagnose flatfoot by examining your feet when you stand and sit.  X-rays may be taken to define the severity and help determine the treatment option best for your condition.  Nonsurgical treatments can include activity modification, weight loss, orthotics, immobilization, medications, physical therapy, shoe modifications, and ankle foot orthoses (AFO) devices.  If nonsurgical methods prove ineffective, surgery may be considered.  Multiple surgical procedures can correct flatfoot; and depending on your specific condition, one may be selected alone or combined with other techniques to ensure optimal results.

Ankle sprains occur when ligaments that support the ankle stretch beyond their limits and tear. These types of injuries are very common and can occur in people of all ages. Sprains may range from mild to severe, depending on how much damage is done to the ligaments. If a sprain goes untreated, a more severe sprain may occur which can further damage the ankle. Repeated ankle sprains can lead to chronic ankle pain.

There are some risk factors that can increase your risk of suffering a sprained ankle. Those who participate in sports, walk on uneven surfaces, have a prior ankle injury, are in poor physical condition, or wear improper shoes are more likely to get a sprained ankle.

There are a few symptoms to look out for if you suspect you are suffering from a sprained ankle. Some common symptoms are swelling, bruising, tenderness, and instability of the ankle. In cases where the tearing of the ligaments is severe, there may be a “popping” sound when the strain occurs.

The RICE method is proven to be effective in treating ankle sprains. RICE stands for Rest, Ice, Compression, and Elevation. Rest is important for treatment, especially within the first 24 to 48 hours. You should also ice your sprained ankle for the first 48 hours for 20 minutes at a time. A small piece of cloth should be placed between the ice and the affected area. For the compression step, you should wear a brace that is snug, but not too tight that it cuts off circulation. When choosing a brace, be sure to choose one that is suitable for the type of ankle sprain you have. Lastly, you should elevate your foot above the heart as often as possible.

After you treat a sprain, you should go through rehabilitation to prevent the injury from occurring again. There are three phases to the rehab process. The first phase involves resting, protecting, and reducing the swelling of the injury. The second phase consists of restoring the ankle’s flexibility, range of motion, and strength. The third phase consists of slowly returning to activity and maintenance exercises.

If you suspect you have an ankle sprain, you shouldn’t hesitate to consult with your podiatrist. Your podiatrist will be able to give you a proper diagnosis and a suitable treatment option for your condition.

Diabetes affects millions of people every year. Blood vessels located all over the body are damaged due to diabetes—even the blood vessels of the feet. Neuropathy, or nerve damage, can result from slower blood flow in the legs and feet. In diabetic patients, neuropathy is very important to monitor, as diabetics are at risk for developing ulcers.

Always washing and thoroughly drying the feet are pertinent parts of diabetic foot care. There should be a focus on cleaning between the toes. Even if no pain is felt, the entire foot should be examined for redness and sores. Neuropathy can often mask the pain of sores and ulcers and can cause these conditions to be overlooked. Use a mirror to examine the underside of your feet if needed. It is recommended that diabetics wear well-fitting socks.

Patients with diabetes should have their doctor monitor their blood levels because blood sugar levels play a huge role in diabetic care. Monitoring these levels on a regular basis is highly advised. It is very important to keep your blood sugar levels in the normal range, which can be determined by your physician. There are medications that may be prescribed to help with any neuropathy experienced by the diabetic patient. It is also advisable to visit a podiatrist if one is experiencing any conditions involving the feet, such as ingrown toenails, which in more severe cases can cause infection.

Diabetic feet must be inspected daily. Diabetic foot care at home is possible if a patient is provided with instructions from their podiatrist. Patients can relieve dry heels with creams or ointments. Suspected wounds should warrant an immediate call to the podiatrist. Gangrene is a serious problem for diabetics and can lead to sepsis and amputation in its worst cases. Early treatment and daily inspection of diabetic feet are keys to staying healthy.
