APA Dictionary of Psychology

n. a type of deformity in which the foot is twisted out of normal position, resulting—in most cases—in more than one positional distortion (e.g., the foot may be turned inward and downward, outward and upward, or in some other variation). Clubfoot may be congenital, or the condition may be due to injury or disease, such as poliomyelitis. Clubfoot often is associated with another anomaly, such as meningomyelocele. Also called talipes.
