Age determination by the histomorphometry of female ribs / 中国法医学杂志

ABSTRACT

The purpose of this paper is to study the pattern of change which are age associated,so as to provide a new method of age estimation by bone for forensic medicine and anthropology.The middle one third of right ribs were collected from 67 Chinese females living in North China.Decalcified cross section slides were histomorphometrically examined by using an image analyzer.Then the parameters were subjected to multiple stepwise regression analysis to produce an equation=31 264+0 868X 2+286 693X 4+0 689 X 7-778 874X 8-0 006X 9.The multiple correlation coefficient and standard error of estimate were 0 923 and 4 08,respectively.When the formula was checked by 25 specimens,84% of the estimated ages fall within ?5 years of actual ages,and 100% of the estimated ages fall within ?8 years of actual ages.This showed that female ages could be deter mined by the histomorphometry of ribs.
