title: [Peculiarities of wrist bone growth as a criterion for determining the biological age of children living under different environmental conditions].
abstract: The paper had the objective to study growth dynamics of short tubular wrist bones in children aged from 5 to 16 years and residing in the cities of Shelekhov and Irkutsk. The growth rate in the girls from Irkutsk was shown to be fairly uniform and proportional; in the boys, it substantially increased at the age of 10-11 and 15 years. In the boys living in Shelekhov, the bone growth became activated at the age of 9 and 15 years. In the girls, it was periodically uniform until the age of 9; thereafter, periodicity in the growth of middle and distal phalanxes was no longer apparent.
