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.

Tarsal coalition is a bone condition that causes decreased motion or absence of motion in one or more of the joints in the foot. The bones found at the top of the arch, the heel, and the ankle are referred to as the tarsal bones. A tarsal coalition is an abnormal connection between two of the tarsal bones in the back of the foot or the arch. This abnormal connection between two bones is most commonly an inherited trait.

The lack of motion or absence of motion experienced in a tarsal coalition is caused by abnormal bone, cartilage, or fibrous tissue growth across a joint. When excess bone has grown across a joint, it may result in restricted or a complete lack of motion in that joint. Cartilage or fibrous tissue growth can restrict motion of the affected joint to varying degrees, causing pain in the affected joint and/or in surrounding joints.

Symptoms usually include an aching sensation deep in the foot near the ankle or arch, accompanied by muscle spasms on the outside of the affected leg. Nonsurgical treatments, such as corrective shoes or custom orthotics, physical therapy, and anti-inflammatory medication, are the first courses of action. Note: Please consult your physician before taking any medications. Surgery is sometimes performed in severe cases to allow for more normal motion between the bones or to fuse the affected joint or surrounding joints.
