Abstract: A new method of sex detemination of clavicles was developed. The sample consisted of 279 pairs of Chinese clavicules of known sex (male, 241; female, 38). The age range is 17-78 years. The seven measurements were taken, including: Maximum length of clavicle, Hohe der diaphysenkrummung, Krummung der akromialen ends der clavicula, Lange der sehne der diaphysenkrummung clavicula, height of the clavicle at mid-point, sagittal diameter of the clavicle at mid-point, circumference of the clavicle at mid-point. New indexes of clavicle was constructed as follow:
ICA =(Max.Leng.Clavi. * Circum.Mid.Clavi.)/100
(ICA: Index of clavicular area)
ICCS=(Heig.Mid.Clavi. * Sagi.Mid.Clavi.)/100
(ICCS: Index of clavicular cross section)
The discriminant values (DV) of sex estimation are 48. 95(ICA) and 1.125(ICCS). The indexes>DV means male, otherwise means female. The rate of sex determination with the new indexes is from 79.57% to 90.86%.
