Figure 2 Bilateral hand-wrist radiograph demonstrating bone age assessment consistent with chronological agePosteroanterior radiographs of the bilateral hands and wrists show normal ossification patterns of the carpal bones, metacarpals, and phalanges. Bone age was assessed using the Greulich and Pyle atlas and was estimated at 1 year and 6 months, compared with chronological age of 2 years and 1 month. The 6-month difference falls within the normal variation for bone age. No abnormal epiphyseal maturation, advanced ossification, or skeletal dysplasia was identified. R and L indicate the right and left hands, respectively.
