Glossary

Arch - The arch of the foot is the area of the bottom of the foot between the heel pad and toe pad.

Acrokeratosis verruciformis - a hereditary dermatosis characterized by the presence of numerous flat wart-like papules on the dorsal aspect of the hand, foot, elbow, and knee.

Ankle - the part of the leg just above the foot; the joint between the leg and the foot. It is a hinge joint formed by the junction of the tibia and fibula with the talus, or ankle bone. The bones are cushioned by cartilage and connected by a number of ligaments, tendons, and muscles that strengthen the joint and enable it to be moved. Because it is in almost constant use, the ankle is particularly susceptible to injuries, such as sprain and fracture. It is also often one of the first joints to be affected by arthritis or gout.

Ankle clonus - a series of abnormal reflex movements of the foot, induced by sudden dorsiflexion, causing alternate contraction and relaxation of the triceps surae muscle.

Athlete's foot - a fungal infection of the skin of the foot; called also tinea pedis. It causes itching and often blisters and cracks, usually between the toes. Causative agents are Candida albicans, Epidermophyton floccosum, and species of Trichophyton, which thrive on warmth and dampness. If not arrested, it can cause a rash and itching in other parts of the body as well. It is likely to be recurrent, since the fungus survives under the toenails and reappears when conditions are favorable. Although Athlete''s foot is usually little more than an uncomfortable nuisance, its open sores provide excellent sites for more serious infections. Early treatment and health care supervision insure correct diagnosis and prevention of complications. Specific diagnosis is made by microscopic examination or culture of skin scrapings for the fungus.

Diabetes is a lifelong chronic disease that is caused by high levels of sugar in the blood. It can also decrease your body's ability to fight off infections, which is especially harmful in your feet. When diabetes is not properly controlled, damage can occur to the organs and impairment of the immune system is also likely to occur.

With damage to your nervous system, you may not be able to feel your feet properly. Normal sweat secretion and oil production that lubricates the skin of the foot is impaired, which can lead to an abnormal pressure on the skin, bones, and joints of the foot during walking and other activities. This can even lead to the breakdown of the skin of the foot, which often causes sores to develop. If you have diabetes, it is important to prevent foot problems before they occur, recognize problems early, and seek the right treatment when a problem does happen.

Diabetic Complications and Your Feet

When it comes to your feet, there are several risk factors that can increase your chances of developing foot problems and diabetic infections in the legs and feet. First of all, poorly fitting shoes are one of the biggest culprits of diabetic foot complications. If you have red spots, sore spots, blisters, corns, calluses, or consistent pain associated with wearing shoes, new proper fitted shoes must be obtained immediately. Additionally, if you have common foot abnormalities such as flat feet, bunions, or hammertoes, prescription shoes or orthotics from your podiatrist may be necessary to further protect your feet from other damage.

People who have long-standing or poorly controlled diabetes are also at risk for having damage to the nerves in their feet, which is known in the medical community as peripheral neuropathy. If you have nerve damage, you may not be able to feel your feet normally and you may also be unable to sense the position of your feet and toes while walking and balancing, which can cause even more harm to your feet.

Normal nerves allow people to sense if their shoes are too tight or if their shoes are rubbing on the feet too much. With diabetes, you may not be able to properly sense minor injuries, such as cuts, scrapes and blisters-all signs of abnormal wear, tear, and foot strain. The following can also compromise the health of your feet:

  • Poor circulation
  • Trauma to the foot
  • Infections
  • Smoking

Diabetes can be extremely dangerous to your feet, so take precautions now. You can avoid serious problems such as losing a toe, foot, or leg by following proper prevention techniques offered by your podiatrist. Remember, prevention is the key to saving your feet and eliminating pain.
