Cross-sectional study of skeletal maturation in normal children from Nottingham and London

The TW2 method (Tanner et al. 1975) was used to evaluate skeletal maturation in 173 children from Nottingham and 120 children from London WC1 . All of the children from Nottingham had hand-wrist injuries and were attending the Accident and Emergency Department of the Children's Hospital, Nottingham. The London children were all a part of a longitudinal growth study, which started in 1952-1953. When compared with the TW2 centiles, the Nottingham children showed retardation, and the London children advancement in skeletal maturation.
