Skeletal age changes in puberty.

Changes in skeletal age and height of 34 Leeds schoolboys were studied in a four year longitudinal survey covering puberty. Tanner and Whitehouse method TW2 was used. In each boy, skeletal age advanced rapidly during puberty, reaching a peak at an age related to that of peak height velocity. The importance of recognising that this acceleration of bone age is normal is stressed, in order to avoid attributing it to other causes.
