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.

Hammertoes are painful deformities that frequently form on the second, third, or fourth toe. The condition is often caused by an issue in foot mechanics. This can be caused by the person’s specific gait or the manner in which they walk, or by shoes that do not comfortably fit the deformity.  Hammertoes can be formed after wearing shoes that are too narrow or short for the foot or have excessively high heels. Shoes that are not properly sized will force the toes into a bent position for long periods of time. This can cause the muscles to shorten and toes to bend into the deformity of a hammertoe.

Hammertoe can also be caused by complications from rheumatoid arthritis, osteoarthritis, trauma to the foot, heredity, or a cerebral vascular accident. Pain and difficult mobility of the toes, deformities, calluses, and corns are all symptoms of a hammertoe.

Someone who suspects they have the symptoms of a hammertoe should consult with a physician—particularly a podiatrist. Podiatrists diagnose and treat complications of the foot and ankle. If the podiatrist discovers that the affected toes are still flexible, treatment for the hammertoe may simply involve exercise, physical therapy, and better-fitting shoes. Treatment for hammertoes typically involves controlling foot mechanics, such as walking, through the use of customized orthotics.

For more serious cases in which the toes have become inflexible and rigid, surgery may be suggested. During the operation, the toe would receive an incision to relieve pressure on the tendons. A re-alignment of the tendons may then be performed by removing small pieces of bone to straighten the toe. In some cases, the insertion of pins is needed to keep the bones in the proper position as the toe heals. The patient is usually allowed to return home on the same day as the surgery.

If surgery is performed to repair a hammertoe, following the postoperative directions of your doctor is essential. Directions may include several stretches, picking up marbles with your toes, or attempting to crumple a towel placed flat against your feet. Wear shoes that have low heels and a wide amount of toe space to maintain comfort. Closed-toe shoes and high heels should be avoided. Shoes with laces allow the wearer to adjust how fitted he or she may want the shoes to be and also allow for greater comfort. To provide adequate space for your toes, select shoes that have a minimum of one-half inch of space between the tip of your longest toe and the inside of the shoe. This will also relieve pressure on your toes and prevent future hammertoes from forming.

Other preventative measures that can be taken include going shopping for new shoes in the middle of the day. Your feet are its smallest in the morning and swell as the day progresses. Trying on and purchasing new shoes midday will give you the most reliable size. Be sure to check that the shoes you purchase are both the same size. If possible, ask the store to stretch out the shoes at its painful points to allow for optimum comfort.  

There are several systemic diseases, or diseases that affect the whole body, that either display symptoms in the feet or affect the health of the feet. Common systemic diseases that affect the overall health of the feet, and the patient’s ability to walk comfortably, include gout, diabetes mellitus, neurological disorders, and arthritis, among others.

In gout, which is caused by an excessive buildup of uric acid in the body, the most common symptoms of pain, inflammation, and redness occur at the metatarsal/phalangeal joint at the base of the big toe. Any excess levels of uric acid crystallize and are deposited in tendons, joints, and surrounding bone and muscle tissue. Gout is commonly treated with NSAIDs to relieve pain and inflammation and other drugs to lower uric acid levels in the body. Gout most commonly affects those who are overweight, have low protein diets and lead a more sedentary lifestyle.

Diabetes mellitus is an increase in the level of blood sugar in which the body cannot counteract with naturally occurring insulin in the body. The three types of diabetes, Type I, Type II and Gestational Diabetes, are all signs the body is either not producing enough insulin or is not efficiently using the insulin that is produced. Gestational diabetes only affects women who are pregnant and have never, prior to pregnancy, exhibited symptoms of the disease.

There are two main issues that affect the feet that are commonly caused by diabetes. They include diabetic neuropathy and peripheral vascular disease. Diabetic neuropathy can lead to damaged nerves and affect the feet through numbness and loss of sensation. Peripheral vascular disease restricts the flow of blood to the foot and can, in extreme cases, lead to the necessity of amputating the foot. Peripheral issues that are caused by diabetes and can affect the foot include athlete’s foot, nail infections, corns, blisters, bunions, severe dry skin, plantar warts and ingrown toenails. These can all be attributed to the decrease of blood flow to the foot.

Neurological disorders and rheumatoid arthritis can also have severe impact on the health of the feet. Neurological disorders can affect the nerves in the main structure of the foot and cause loss of sensation and possible decreased muscle response. Rheumatoid arthritis can affect the bones and joint structures of the foot, making it impossible to walk normally without serious pain.

All systemic diseases that affect the foot can effectively be treated to minimize joint and muscle damage if they are diagnosed early and treated with medication and lifestyle therapy. Diabetes patients must monitor their blood sugar levels and work with their physician to keep their levels as close to normal as possible. Rheumatoid arthritis patients should work with their physician to ensure the proper medications are being taken to reduce the amount of damage to the joints of the body.
