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.

Swelling of the feet, ankles and legs, also known as edema, is often caused by an abnormal build-up of fluids in ankle and leg tissues. Painless swelling of the feet and ankles is a common problem, particularly in older people. It may affect both legs, including the calves and/or thighs. Because of gravity, swelling is particularly noticeable in the lower legs. Swelling in the legs and feet may also be a symptom of other, more serious health issues, such as heart failure, renal failure, or liver failure.

Common causes of foot, ankle, and leg edema include:

  • Blood pressure-lowering drugs.
  • Body fluid overload.
  • Burns.
  • Certain antidepressants.
  • Congestive heart failure.
  • Diagnostic tests.
  • Environment.
  • Estrogens and progestin oral contraceptives.
  • Extremity surgery.
  • Generalized allergy.
  • Glomerulonephritis or other kinds of kidney disorders.
  • Infiltration of an intravenous site.
  • Injury or trauma to the ankle or foot.
  • Insect bite or sting.
  • Long airplane flights or automobile rides.
  • Long-term corticosteroid therapy.
  • Medical treatments.
  • Medications.
  • Menstrual periods (for some women).
  • Pregnancy (mild to severe swelling).
  • Prolonged standing.
  • Starvation or malnutrition.
  • Sunburn.
  • Testosterone.
  • Venogram.
  • Venous insufficiency (varicose veins).

You can mitigate swelling by elevating your legs above the heart while lying down. Avoid sitting or standing without moving for prolonged periods of time. Avoid putting anything directly under the knees when lying down, and don't wear constricting clothing or garters on the upper legs.

Exercising the legs causes the fluid to work back into the veins and lymphatic channels so that the swelling goes down. Mild pressure applied by elastic bandages or support stockings can help reduce ankle swelling. A low-salt diet may also help reduce fluid retention and decrease the ankle swelling.
