Humerus Morfometrisi ve Cinsiyet ile İlişkisinin Bilgisayarlı Tomografi Yöntemi ile İncelenmesi

Abstract

The primary step in the identification of human remains is sex determination of the individual. Bone morphometry may vary between populations, which necessitates the development of population-specific studies for sex determination. The first aim of this study is to identify the morphological and morphometric parameters on the humerus that exhibit sexual dimorphism in the Turkish population, while the second aim is to assess the effectiveness of these parameters both individually and in combination in sex determination. In this study, 172 humeri (86 male, 86 female) were analyzed by using peripheral upper extremity computed tomography angiography. Humeral volume and length, epicondylar width, morphometry of midshaft, head of humerus, intertubercular groove and medial epicondyle and shape classification of inferior border of medial epicondyle were evaluated and the presence of the supratrochlear foramen was also noted. Significant sexual dimorphism was observed in majority of parameters, except for opening angle and the shape classification of the inferior border of medial epicondyle and the presence of the supratrochlear foramen. The transverse length of the head of humerus was detected the most effective single parameter for sex determination, with an accuracy of 92.8% for right humeri, 91% for left humeri, and 91.9% for all of humeri. The combination of the transverse and vertical lengths of the head of humerus was the most effective combination, with an accuracy of 92.8% for right humeri and 93.3% for left humeri. The combination of the transverse length of the head of humerus, the depth of the intertubercular groove and the vertical length of the head of humerus was found to be the most effective combination for sex determination, with an accuracy of 92.4% for all of humeri. We believe that the results of this study will contribute to sex determination studies from humerus in the Turkish population.
