Major foot deformities were analyzed using standardized radiographic drawings of the foot in weight-bearing. Specific criteria and a classification of foot deformities by radiographic analysis are presented, utilizing "lining systems" related to the main bones of the hindfoot.The radiographic appearance of the foot is described and analyzed, as are the principal deformities such as varus and valgus heel and forefoot. The prefixes "talipes" and "pes" have been used to signify congenital and acquired deformities, respectively.Specific foot deformities, including talipes equinovarus (clubfoot), pes planovalgus (flatfoot), pes cavus, and metatarsus varus, are analyzed. This method can also be applied in the radiological analysis of any foot deformity.By using this technique, a brief, concise and simplified analysis of foot deformities is available to the student, general practitioner, and specialist.
