Constitutional delay of puberty x ray

Since bone maturation is a good indicator of overall physical maturation, an x-ray of the hand to assess bone age usually reveals whether the child has reached a stage of physical maturation at which puberty should be occurring. Visible secondary sexual development usually begins when girls achieve a bone age of 10.5 to 11 years, and boys achieve a bone age of 11.5 to 12 years.
