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.


Overlapping toes are characterized by one toe lying on top of an adjacent toe. The fifth toe is the most commonly affected. Overlapping toes may develop in the unborn fetus. Passive stretching and adhesive taping is most commonly used to correct overlapping toes in infants, but the deformity usually recurs. Sometimes they can be surgically corrected by releasing the tendon and soft tissues about the joint at the base of the fifth toe. In some extreme cases, a pin may be surgically inserted to hold the toe in a straightened position. The pin, which exits the tip of the toe, may be left in place for up to three weeks.

Underlapping toes usually involve the fourth and fifth toes. (A special form of underlapping toes is called congenital curly toes). The cause of underlapping toes is unknown. It is speculated that they may be caused by an imbalance in muscle strength of the small muscles of the foot.  If deformed toes are flexible, a simple release of the tendon in the bottom of the toe will allow for them to straighten. If the deformity is rigid, surgery may be needed to remove a small portion of the bone in the toe.
