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.

A neuroma is an enlarged, benign growth of nerves, most commonly between the third and fourth toes. Neuromas are caused by tissue rubbing against and irritating the nerves. Pressure from poorly fitting shoes or an abnormal bone structure can also lead to this condition. Symptoms may include sensations of thickness, burning, numbness, tingling, or pain in the ball of the foot.  Treatments generally include wearing corrective shoes or orthotics and/or receiving cortisone injections. In severe cases, surgical removal of the growth may be necessary.

Morton's neuroma is a thickening of tissues around the nerve that leads to the toes. Morton's neuroma usually develops between the third and fourth toes in response to irritation, such as that caused by wearing high-heeled or narrow shoes, or from trauma. Symptoms may include a burning pain that radiates from the ball of the foot to the toes or numbness in the toes. Conservative treatments usually resolve the pain or progressions of the condition, and range from wearing roomier, lower-heeled footwear or using orthotics to reduce the pressure on the nerve, to injections of corticosteroid medication to reduce swelling and inflammation.
