    Sexual Dimorphism in Humerus: A Study on Egyptians
    (Sebha University, 2006) Anas M. Abo Samak, Magdy M. Ashmawy Mona M. Attia
    The present study aims to detect the possibility of sex discrimination from humeral measurements in Egyptians. One hundred normal right humeri were taken from one hundred cadavers (54 males and 46 females) above 20 years of age and belong to the Egyptian population. Six measurements of maximum length, vertical head diameter, midshaft circumference, minimum midshaft diameter, maximum midshaft diameter and epicondylar breadth were taken for each humerus. The measurements were statistically analyzed. The results revealed that the measurements of males were significantly higher than those of females (P < 0.001). Maximum length was the most discriminating variable in sex determination with 90% rate of accuracy, followed by midshaft circumference (86%) then minimum midshaft diameter (82%). Combination of two variables revealed that minimum midshaft diameter with epicondylar breadth gave the highest rate of accuracy for correct sex prediction with accuracy rate of 88%. The results of the study can help in the prediction of sex from the humerus in Egyptians when other human remains, suitable for sex determination, are not available.
