“…The sexual dimorphism in the human skeleton system is well studied (10,(39)(40)(41)(42)(43)(44)(45)(46). Researchers keep on exploring the potential of bones in sex estimation, for instance, mandible (47), long bones of the upper limb (44,46,48), metacarpals and phalanges (45), pelvis (41,42), tibia (9), metatarsal (19,49,50), and proximal foot phalanges (51). The accuracy of sex estimation provided by different parts of the bone varied ranged from 66% to 99%.…”

The aim of the present paper is to determine the sex of the individual using three-dimensional geometric and inertial analyses of metatarsal bones. Metatarsals of 60 adult Chinese subjects of both sexes were scanned using Aquilion One 320 Slice CT Scanner. The three-dimensional models of the metatarsals were reconstructed, and thereafter, a novel software using the center of mass set as the origin and the three principal axes of inertia was employed for model alignment. Eight geometric and inertial variables were assessed: the bone length, bone width, bone height, surface-area-to-volume ratio, bone density, and principal moments of inertia around the x, y, and z axes. Furthermore, the discriminant functions were established using stepwise discriminant function analysis. A cross-validation procedure was performed to evaluate the discriminant accuracy of functions. The results indicated that inertial variables exhibit significant sexual dimorphism, especially principal moments of inertia around the z axis. The highest dimorphic values were found in the surface-area-to-volume ratio, principal moments of inertia around the z axis, and bone height. The accuracy rate of the discriminant functions for sex determination ranged from 88.3% to 98.3% (88.3%–98.3% cross-validated). The highest accuracy of function was established based on the third metatarsal bone. This study showed for the first time that the principal moment of inertia of the human bone may be successfully implemented for sex estimation. In conclusion, the sex of the individual can be accurately estimated using a combination of geometric and inertial variables of the metatarsal bones. The accuracy should be further confirmed in a larger sample size and be tested or independently developed for distinct population/age groups before the functions are widely applied in unidentified skeletons in forensic and bioarcheological contexts.

“…The HHVD of the Portuguese population Gonçalves (2014) had a section point of 42.36 mm, which is a smaller dimensional reference than that obtained in this northeastern Brazilian sample, whose value was 42.87 mm. The HEW cutoff point for the Portuguese population Gonçalves (2014) This variability in the dimensional values of the cutoff points highlights the population specificity of the metric methods for sex diagnosis since the measurements of bone structures can be influenced due to geographic and temporal aspects, different social and nutritional customs, and degrees of physical demands Coma (1999), Vick (2005), Frutos (2005), Stulp and Barrett (2016), Siddiqi and Norrish (2018), Colman et al (2018), Maass and Friedling (2018), Musilová et al (2019). Ancestry can also interfere in sex diagnosis, with metric similarities being registered in populations of the same ancestry Boldsen et al (2015), an increase in assertiveness with the inclusion of this variable Maass and Friedling (2018), in addition to the relationship of bone length and thickness and robustness with characteristics specific to European and African descendants Spradley and Jantz (2011), Colman et al (2018).…”

This research aimed to assess the predictive ability and applicability for sexual diagnosis of algorithms developed from measurements of humeri and femurs from skeletons belonging to the CEAF Identified Skeletal Collection of the University of Pernambuco, Brazil. The sample was composed of 483 humeri and 452 femurs, obtained from 401 skeletons, 208 male and 193 female, with ages ranging from 15 to 109 years. The variables used were the transverse and vertical diameters of the humeral and femoral heads and the epicondylar width of these bones. The data collected were analyzed using R software (version 3.6.1, R Foundation for Statistical Computing). Only the univariate logistic regressions were considered predictive, making it possible to estimate sex based on any single variable in this study. The accuracy ranged from 93.8% to 97.5% for the humerus evaluation and from 92.9% to 95.6% for femurs, with the transverse diameter of the right humeral head being the most dimorphic measurement. Therefore, it is inferred that the sexual dimorphism present in the measurements of the humeri and femurs of our sample is high and enables the classification of sex reliably and assertively using the algorithms created.

“…Metric studies mainly use several statistical methods as discriminant function analysis (DFA) to produce models or equations for sex prediction (6) . The best accurate method to assess sex from bone size is relied on pelvic bones or skull, However in many cases and after mass disasters they may be absent, so the development of approaches of sex identifications from other bones is vital (7) . Approximately 6 inches (15 cm) in length, the clavicle is an elongated, S-shaped bone that connects the shoulder blades to the chest wall.…”

Background: Precise sex assessment relies over dimorphic dimensions measuring among unknown human remains is a necessary prerequisite for individuals' identification. Clavicle is a flat short bone appears to be better maintained than long bones. Anthropometric analyses of clavicles to determine the sex are evaluated in different populations with high accuracy. Three-dimensional computed tomography (3D-CT) pictures are an effective technique for this. Objective:The aim of the current study was to study sexual dimorphism of the clavicle, as well as establishment of sex prediction equation among Libyan people by utilizing measurements of the clavicle which obtained from 3D-CT images. Subjects and methods: A total of 50 males and 50 females sexes dimensions were measured from 3D CT scans of the left clavicle: C1, C2 and C3 maximum clavicular length, midshaft circumference, and maximum diameter of the midshaft. C4, C5 and C6 indicated minimum midshaft diameter, maximum sternal end, and acromial end widths, respectively. Results: All the studied measurements in the left clavicle showed a statistical significant increase in males compared to females. C4 was the most single sexually dimorphic dimension of the left clavicle with 90% accuracy. Stepwise discriminant analyses of clavicular variables (C2, C4, and C6) yielded high accuracy at the rate of 99 % (99 % crossvalidated). Conclusion: 3D-CT morphomertric analyses of clavicle provide valuable data for identification of sex in modern Libyan population and can be used in forensic investigations.
