title: Skeletal maturity in seven year old Dunedin children.
abstract: A study of 433 boys' and 403 girls' left hand/wrist radiographs taken within 0.1 years of the child's seventh birthday shows that the median equivalent skeletal maturity using the TW 2 20-bone score is identical to the English standards, and the RUS score is only slightly above the standards. It is thus valid to use Tanner's standards when assessing New Zealand white children. The wide range of values in a healthy population is stressed.
