The following resources contain terminology when referring to treatments, education, surgery and medically related information pertaining to the feet.
The arch of the foot is the area of the bottom of the foot between the heel pad and toe pad.
A hereditary dermatosis characterized by the presence of numerous flat wart-like papules on the dorsal aspect of the hand, foot, elbow, and knee.
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.
A series of abnormal reflex movements of the foot, induced by sudden dorsiflexion, causing alternate contraction and relaxation of the triceps surae muscle.
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 reflex action of the toes, normal during infancy but abnormal after 12 to 18 months of age, or when locomotion begins; after this, it is indicative of abnormalities in the motor control pathways leading from the cerebral cortex and is widely used as a diagnostic aid in disorders of the central nervous system. It is elicited by a firm stimulus (usually scraping) on the sole of the foot, which results in dorsiflexion of the great toe and fanning of the smaller toes. Normally such a stimulus causes all the toes to bend downward. Called also Babinski`s sign.
A prosthetic foot that allows ankle motion.
An abnormal prominence on the inner aspect of the first metatarsal head, with bursal formation, and resulting in lateral or valgus displacement of the great toe. Bunions can be caused by congenital malformation of the bony structure of the foot or by joint disease such as rheumatoid arthritis and are aggravated by wearing high-heeled shoes with pointed toes. When the shoes do not fit properly they force the great toe toward the outer side of the foot. The result is continued pressure on the joint where the great toe articulates with the first metatarsal head. Chronic irritation causes a build-up of soft tissue and underlying bone in the area. Symptoms are swelling, redness, and pain. Mild cases can be relieved by changing to properly fitting shoes. If there is severe pain making ambulation difficult or impossible, anti-inflammatory agents may be effective. Surgical correction (bunionectomy) is indicated when all other measures fail.
The hindmost part of the foot; the heel.
Affecting the wrist and foot.
A burning pain often associated with trophic skin changes in the hand or foot, caused by peripheral nerve injury. The syndrome may be aggravated by the slightest stimuli or it may be intensified by the emotions. Causalgia usually begins several weeks after the initial injury and the pain is described as intense, with patients sometimes taking elaborate precautions to avoid any stimulus they know to be capable of causing a flare-up of symptoms. They often will go to great extremes to protect the affected limb and become preoccupied with such protection. Any one of a variety of injuries to the hand, foot, arm, or leg can lead to causalgia, but in most cases there has been some injury to the median or the sciatic nerve. Injections of a local anesthetic at the painful site may bring relief. Sympathectomy may be necessary to eliminate the severe pain, and in the majority of cases it is quite successful. Psychotherapy may be necessary when emotional instability is suspected. Emotional problems may have been present before the initial injury, or they may result from the intense suffering characteristic of severe causalgia.
Amputation of the foot, with the calcaneus, talus, and other parts of the tarsus being retained.
A high-arched foot with the toes hyperextended at the metatarsophalangeal joint and flexed at the distal joints.
Deformity in which the foot is twisted out of normal position; called also talipes. The foot may have an abnormally high longitudinal arch (talipes cavus) or it may be in dorsiflexion (talipes calcaneus) or plantar flexion (talipes equinus), abducted, everted (talipes valgus), adducted, inverted (talipes varus), or various combinations of these (talipes calcaneovalgus, talipes calcaneovarus, talipes equinovalgus, or talipes equinovarus). There are several theories as to the cause of clubfoot. A familial tendency or arrested growth during fetal life may contribute to its development, or it may be caused by a defect in the ovum. It sometimes accompanies meningomyelocele as a result of paralysis. In mild clubfoot there are slight changes in the structure of the foot; more severe cases involve orthopedic deformities of both the foot and leg. Although clubfoot is usually congenital, an occasional case in an older child may be caused by injury or poliomyelitis.

A general term for a group of eukaryotic organisms (mushrooms, yeasts, molds, etc.) marked by the absence of chlorophyll, the presence of a rigid cell wall in some stage of the life cycle, and reproduction by means of spores.

Among the fungal diseases (mycoses) are “histoplasmosis, coccidioidomycosis, ringworm, histoplasmosis, coccidioidomycosis, ringworm, Athlete`s foot, and thrush. Although the fungal diseases develop slowly, are difficult to diagnose, and are resistant to treatment, they are rarely fatal except for systemic mycotic infections, which can be life-threatening, especially for immunocompromised patients.
