- Abstract
Aims. Lately, the interest in establishing objective ways of determining the sex based on bone measurements moved from pelvic bones and skull to the limbs skeleton. More recent studies have included the radius and ulna, which, although not as robust, being smaller and more fragile than the femur or tibia, the accuracy of discriminant functions for sex determination based on the dimensions of the forearm bones is quite high. Material and methods. The study included 50 adult subjects (25 male and 25 female). We measured the length of tibia, radius and ulna, using a measuring tape. Results. In the present study, using as an indicator of sexual dimorphism tibia length, we obtained an accuracy of 92% for males and 76% for women and 84% overall accuracy. For radius length, accuracy of the discriminant function is only 76% for males and 88% for females, and the overall 82%. For ulna length, the accuracy is 76% for males and 84% for women, so an overall accuracy of 80%. If discrimination function was based on all three variables, the accuracy was 76% for males, 80% for females, and the overall 78%. Conclusions. The existence of standardized data and specific formulas for the population of each country and time period is mandatory for an accurate determination of sex using long bones length. In this respect, the present study is a very useful tool as it reffers to actual morphometric characteristics of the population of Romania.
