Orthotics are shoe inserts that are meant to correct an irregular walking gait or provide cushioning to the feet.  Orthotics come in a variety of different models and sizes, including over-the-counter and customizable variants. Customizable orthotics can be shaped and contoured to fit inside a specific shoe and are typically prescribed through a podiatrist who specializes in customized footwear and orthotics design and management.

Orthotics are beneficial because they can help prevent injuries from occurring and provide cushioning to keep pain levels down to a minimum. They also allow for the correct positioning of the feet. Orthotics can act as shock absorbers to help remove pressure from the foot and ankle. Therefore, orthotics can make bodily movements, such as walking and running, become more comfortable as well as help prevent the development of certain foot conditions.

Orthotics alleviate pain and make the foot more comfortable by slightly altering the angle at which the foot strikes the ground surface, therefore controlling the movement of the foot and ankle. Orthotics come in different variants and can be made of various materials. To determine what type of orthotic is most suited to your feet and your needs, it is best to consult your podiatrist. He or she will be able to recommend a type of orthotic that can help improve your foot function or prescribe a custom orthotic to best fit your feet.  

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.

Neuropathy is a condition in which the nerves in the body become damaged from a number of different illnesses. Nerves from any part of the body, including the foot, can be damaged. There are several forms of neuropathy including peripheral neuropathy, cranial neuropathy, focal neuropathy, and autonomic neuropathy. Furthermore there is also mononeuropathy and polyneuropathy. Mononeuropathies affect one nerve while polyneuropathies affect several nerves. Causes of neuropathy include physical injury, diseases, cancers, infections, diabetes, toxic substances, and disorders. It is peripheral neuropathy that affects the feet.

The symptoms of neuropathy vary greatly and can be minor such as numbness, sensation loss, prickling, and tingling sensations. More painful symptoms include throbbing, burning, freezing, and sharp pains. The most severe symptoms can be muscle weakness/paralysis, problems with coordination, and falling.

Podiatrists rely upon a full medical history and a neurological examination to diagnose peripheral neuropathy in the foot. More tests that may be used include nerve function tests to test nerve damage, blood tests to detect diabetes or vitamin deficiencies. Imaging tests, such as CT or MRI scans, might be used to look for abnormalities, and finally nerve or skin biopsies could also be taken.

Treatment depends upon the causes of neuropathy. If the neuropathy was caused by vitamin deficiency, diabetes, infection, or toxic substances, addressing those conditions can lead to the nerve healing and sensation returning to the area. However if the nerve has died, then sensation may never come back to the area. Pain medication may be prescribed for less serious symptoms. Topical creams may also be tried to bring back sensation. Electrical nerve stimulation may be used for a period of time to stimulate nerves. Physical therapy can strengthen muscle and improve movement. Finally surgery might be necessary if pressure on the nerve is causing the neuropathy.

If you are experiencing sensation loss, numbness, tingling, or burning sensations in your feet, you may be experiencing neuropathy. Be sure to talk to a podiatrist to be diagnosed right away.

Tarsal tunnel syndrome is a condition in which there is a compression of the posterior tibial nerve. The posterior tibial nerve runs along the inside of the ankle into the foot. Tarsal tunnel syndrome is named for the tarsal tunnel, which is a thin space along the inside of the ankle beside the ankle bones. This space contains various nerves, arteries, and tendons, and includes the posterior tibial nerve. The tibial nerve is the peripheral nerve in the leg responsible for sensation and movement of the foot and calf muscles. In tarsal tunnel syndrome the tibial nerve is compressed, causing tingling or burning, numbness, and pain.

Common causes of tarsal tunnel syndrome involve pressure or an injury. Injuries that produce inflammation and swelling in or around the tunnel may place pressure on the posterior tibial nerve. Direct pressure on the tibial nerve for an extended period of time, sometimes caused by other body structures close by or trauma to the tibial nerve, can result in tarsal tunnel syndrome. Diseases that damage nerves, such as diabetes or arthritis, may cause tarsal tunnel syndrome. Those with flat feet are at risk for developing the condition, as the extra pressure and strain placed on the foot may compress the posterior tibial nerve.

Feeling different sensations in the foot at different times is a common symptom of tarsal tunnel syndrome. An afflicted person may experience pain, tingling, burning or other unusual sensations in the foot of the affected leg. Symptoms are primarily felt on bottom of the foot and/or the inside of the ankle. Symptoms can appear suddenly and may occur due to overuse of the foot.

To diagnose tarsal tunnel syndrome, your podiatrist may examine the foot and tap the posterior tibial nerve to see if symptoms surface. He or she may also order an MRI to determine if a mass is present.

Treating tarsal tunnel syndrome will depend on the decision of your podiatrist. Multiple options are available, however, and can include rest, ice, immobilization, oral medications such as anti-inflammatory drugs (NSAIDS), physical therapy, injection therapy, orthotics, supportive shoes, braces, and surgery.

Corns are hard and thick areas of skin that form as a result of constant rubbing, friction, or pressure on the skin. They are patches of dead skin with a small plug toward the center. They may appear on the tops and sides of toes and can make walking painful.

Soft corns are typically thinner with a white color and rubbery texture. Soft corns tend to appear between the toes. Seed corns are another type of corn that appear in clusters and can be tender if they are on a weight-bearing part of the foot. Seed corns usually appear on the bottom of the foot and are likely caused by a blockage in sweat ducts.

While corns and calluses are somewhat similar, calluses are a bit different. Calluses are a patch of dead skin that can occur anywhere on the body. In comparison to corns, calluses are usually a bit larger in size. However, both corns and calluses are caused by increased friction on the skin.

There are some risk factors that may increase your chances of developing corns and calluses. If you have bunions, hammertoe, or a bone spur, you are more likely to develop a corn or callus on your foot.

While Corns and Calluses tend to disappear when the friction to the affected area ceases, the help of a podiatrist may be useful in the removal process. It is important to remove the dead skin around the area and this may be done in a few different ways. Moisturizing creams may be helpful in softening and removing the dead skin around the callus. You should never use razors or other pedicure equipment to remove your corns. Doing this may worsen your corn or callus and cause infection. 

In some cases, corns and calluses may be caused by abnormal foot structure or walking motion. In such a case, you should seek a podiatrist’s assistance in order to correct the issue.
