Abstract: Based on the anthropometry of 2612 Han students and the observation of the antero-posterior roentgengraph of the knee of 1361 students born in Xian, this paper provides thirty regression formulae for calculating age and from the degree of epiphyseal fusion in the long bones forming knee joint and some linear measurements.
The estimation of stature from height of tibiale is considered as a better choice. The degree of epiphysis-diaphysis fusion on upper end of fibula is the better information for estimating age. The stepwise regression is suggestible rather than the linear.

Key words: Epiphyseal fusion; Age estimation; Stature estimation
