Developmental flatfoot.

An overview of the clinical entity referred to as developmental flatfoot has been discussed. Specific reference has been made to its occurrence, etiology, identification, pathomechanics, clinical significance, and management rationale. This often overlooked, inconspicuous condition is the most common musculoskeletal abnormality affecting the foot of the child under 6 years of age. Recognition of the fact that the developmental flatfoot is the logical precursor of foot dysfunction, deformity, and resultant disability later in life will allow the practitioner to design a management program for today that will meet the foot health needs of tomorrow.
