Abstract: This paper has reported the skeletal development of hand-wrist in 728 healthy children and adolescent of Tibetan aged from 7 to 18 who were born and live at the altitude of 3000—4000 metres above sea level at Qinghai Tibet Plateau. The authors have calculated the average ages of the appearance of certain ossification centers and of certain epiphyses fusing with their diaphyses and also have discussed the relationships between the skeletal age and the stature spurt, and the menarche.
