Abstract:
Objective To explore the feasibility and accuracy of sex determination by morphology of the distal humerus in North China population. Methods Observing sexually dimorphic differences of olecranon fossa shape, trochlear symmetry, trochlear constriction and angle of medial epicondyle. Each characteristic was divided into three categories: male, unknown and female. The morphological characteristics of the humerus of 70 individuals (35 males and 35 females) from the Ming and Qing Dynasties in North China were counted to compare the occurrence rate of different categories of distal humeral morphology and the accuracy rate of sex determination. Results There were statistically significant differences in the performance of the four traits of the distal humerus between males and females. The accuracy rate of angle of medial epicondyle was the highest at 76%, while the lowest accuracy rate of trochlear constriction was only 52%. The accuracy of the combined four traits was higher than the single ones, with an accuracy rate of 76% (83% for males and 68% for females). Conclusion Distal humerus morphology can be used to determine sex when skulls and pelvis are absent.
