Objective: The aim of this study was to evaluate developmental stages of the radius bone and compare it with the chronological age of Thai population. Methods: Three hundred hand and wrist radiographs (150 males, 150 females) of subjects (age 7-20 years) were retrospectively collected. The developmental stages of the distal end of the radius bone were modified from Tanner-Whitehouse 3 and categorized into 4 stages: 1) non-capping, 2) capping, 3) partial fusion and 4) complete fusion.
