As used to determine bone age, radiography of the hand and wrist is a quick and helpful means of estimating the likelihood of precocious puberty and its speed of progression. If bone age is within 1 year of chronologic age, puberty either has not started or the duration of the pubertal process has been relatively brief. If bone age is advanced by 2 years or more, puberty likely has been present for a year or more or is progressing more rapidly.
