“…Analysis of the logistic regression models revealed that the accuracy for sex determination was 80-85% when only the sternal measurements SA or FRW were used (Table 3). These values are similar to those in the literature [1,3,10]. Model 6 (SA + FRW) had the highest accuracy for sex determination (88.2%) among the models using these sternal measurements together with FRW or using combined SA and FRW (models 3, 4 and 6).…”

“…A study on the European sternum led to the ''149 rule'', according to which the length of the male sternum exceeds 149 mm in length, whereas the length of the female sternum is less than 149 mm [2]. Different population groups such as American Whites and Blacks have been thought to be the main reason for the different numbers in the rules [9,10]. Some studies have emphasized that the sex determination accuracy can be increased when 4th rib measurements and the rib mineralization pattern are taken into account in addition to sternal data [1,11].…”

“…Regarding sexual dimorphism of individual ribs, some studies have addressed this question from a forensic point of view. Specifically, the width and height of the sternal end of the human fourth rib were proposed as dimorphic in the mid‐80s (Işcan, ), a fact that was later confirmed in different populations (Koçak, Aktas, Ertürk, Aktas, & Yemisçigil, —Turkish population; Macaluso, Rico, Santos, & Lucena, —Spanish population; Meena, Mittal, Chouksey, & Rani, —Indian population; Wiredu, Kumoji, Seshadri, & Biritwum, —Ghana population). Meanwhile, Bellemare et al () quantified the rib length of the third, sixth, and ninth ribs of a Canadian population and found no statistical differences in this measurement between both sexes.…”

ABSTRACT Objectives:The human respiratory apparatus is characterized by sexual dimorphism, the cranial airways of males being larger (both absolutely and relatively) than those of females. These differences have been linked to sex-specific differences in body composition, bioenergetics and respiratory function. However, whether morpho-functional variation in the thorax is also related to these features is less clear. We apply 3D geometric morphometrics to study these issues and their implications for respiratory function. Material and methods:402 landmarks and semilandmarks were measured in CT-reconstructions of rib cages from adult healthy subjects (N male =18; N female =24) in maximal inspiration (MI) and maximal expiration (ME). After Procrustes registration, size and shape data were analyzed by mean comparisons and regression analysis. Respiratory function was quantified through functional size, which is defined as the difference of rib cage size between MI and ME.Results: Males showed significantly larger thorax size (p<0.01) and functional size (p<0.05) than females. In addition, the 3D-shape differed significantly between sexes (p<0.01). Male rib cages were wider (particularly caudally) and shorter, with more horizontally oriented ribs when compared to females. While thorax widening and rib orientation were unrelated to allometry, thorax shortening showed a slight allometric signal. Conclusions:Our findings are in line with previous research on sexual dimorphism of the respiratory system. However, we add that thorax shortening observed previously in males is the only feature caused by allometry. The more horizontally oriented ribs and the wider thorax of males may indicate a greater diaphragmatic contribution to rib cage kinematics than in females, and differences in functional size fit with the need for greater oxygen intake in males.3

“…McCormick et al investigated more than 1100 chest plate roentgenograms and reported, that the width of the 4 th costa is more sexually dimorphic than the 2 nd , 3 rd and 5 th costae (Mc Cornick, 1980). In 2003, Kocak et al also confirmed that the sexual dimorphism can be evaluated using the right 4 th costa (Kocak et al, 2003).…”

Objectives: The determination of sex and estimation of age are parameters that help in the identification of individuals in all fields of forensic science. This study aimed to calculate standard measurements according to sex and age in morphometric analysis of the 4th costa using multi-slice computed tomography (MSCT). Methodology: Measurements were taken on MSCT images of patients aged 20-70 years, who had undergone CT imaging for various reasons. Using the morphometric characteristics of the 4th costa and junction with the spine on the thorax CT images, measurements were taken of the angulation of the right and left 4th costa, the distance between the sternum and the vertebra, the distance between the two costae, the distance between the two ends of the right and left 4th costa separately, and the depth of the two costae. Adding age and gender to these variables, 10 parameters were evaluated in total. Results: As a result of the analyses, the mean values of right costovertebral angle, sternum-vertebra distance, inter-costal distance, left and right costa lengths, and left costa depth were found to be statistically significant according to sex. In the differentiation of age groups, the right costovertebral angle, the sternum-vertebra distance, and the right and left costa lengths were found to be statistically significant. Conclusion: The results of this study of a Turkish population showed that the morphometric properties of the 4th costa show differences in the determination of age and sex. With the benefit of these differences, it is possible to differentiate males and females, and even age groups. As there are societal differences, standard morphometric values have to be determined so it will be necessary to conduct these studies more widely and obtain appropriate standard values for every population.
