Sex determination of the human skeleton is best assessed from the os coxa. The present study explored the possibility of using three-dimensional landmark coordinate data collected from various landmarks located over the entire bone to determine whether there were significant sex differences local to the landmarks.
Abstract
Thirty-six landmarks were digitized on 200 African-American and European American male and female adult human os coxae. MANCOVA results show that sex and size have a significant effect on shape for both European Americans (Sex, F = 17.50, d.f. = 36, 63, p greater than F = 0.0001; Size, F = 2.56, d.f. = 36, 63, p greater than F = 0.0022) and African-Americans (Sex, F = 21.18, d.f. = 36, 63, p greater than F = 0.0001; Size, F = 2.59, d.f. = 36, 63, p greater than F = 0.0005). The discriminant analysis shows that sexing accuracy for European Americans is 98 percent for both males and females, 98 percent for African-American females, and 100 percent for African-American males.
