Example 1: A newborn infant is noted to have inward turning of the forefoot on physical examination. This is diagnosed as congenital metatarsus adductus., A 6-month-old infant is brought to the pediatrician because the parents are concerned about the shape of their child's feet. The pediatrician diagnoses congenital metatarsus adductus and recommends observation and stretching exercises., A 2-year-old child with persistent metatarsus adductus is referred to an orthopedist for evaluation and possible casting or bracing.

Documentation should include a description of the physical findings, including the degree of adduction, any associated deformities, and any interventions provided (e.g., stretching, casting, bracing).
