[Dynamics of morphometric parameters of skeletal bone in inhabitants of Saint-Petersburg].

2102 roentgenograms of the left manus bones from both sexes subjects with normal health status aged up to 18 were studied to detect peculiarities of skeleton maturity of St. Petersburg inhabitants. TW-2 modified Tanner-Whitehouse method was used. It was demonstrated that children living in St. Petersburg are characterized with the excess of skeletal age over chronological one almost in all age groups, which is maximum typically during first years and minimum by the end of puberty. The process of bone maturity is not successive. Highest growth rate of skeletal maturity were found in prepubescent and puberty. Sex differences established are also noted. Girls were above boys in skeletal age at 7, 8, 9 and 10 years.
