His growth chart is shown in Fig. 1A. TW2 method) (Fig. 1B). The radiolucency of his metacarpal bones was increased. A scanner was 0.382 g/cm2, and its Z-score based on the densitometer-derived reference value was - 5.8. An X-ray of his spine demonstrated extremely radiolucent vertebral bodies, although obvious fractures were not found (Fig. 1C).
