“…Turkish manubrium measured on CT scans by Ramadan et al 29 and Ekizoglu et al 36 were found to be significantly longer than this study's sternums in both sexes. Mesosternal and the combined sternal lengths of current study sternums were found to be significantly smaller than most other studies compared 29,30,32,33,[35][36][37]39 . Radiographic sternal dimensions were found to be significantly higher than those measured on historical or modern autopsy sternum collections.…”

“…All studies reported significantly higher sternal measurements in males than females. The Northwest Indian manubrium was found to be longer than most studies compared, although statistically significant differences were noticed for the Australian and Japanese male sternums measured on CT scans 33,39 , African sternums of the Dart/Pretoria bone collection 30 Portuguese/Spanish sternums of the San Jose and Coimbra collection 37 and South Indian sternums collected from autopsy cases 38 . Turkish manubrium measured on CT scans by Ramadan et al 29 and Ekizoglu et al 36 were found to be significantly longer than this study's sternums in both sexes.…”

“…Although the sternum finds its suitable place in these studies, the clavicle has remained underrepresented in this endeavour. Either gross bone specimens (clavicle and sternum) collected from autopsied cadavers and some prominent historical bone collections [9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][25][26][27][28]31,32,34,37,38 or their radiographs (in the form of X-rays, CT/MRI scans) from living subjects or of skeletonised remains 8,29,33,35,36,39 have been studied for sex estimations in forensic anthropology. The majority of such studies have reported that osteometric features of these two bones are highly sexually dimorphic and population specific, and show secular variations in their shape and size over a period of time.…”

“…Population-specific discriminant function and logistic regression equations for estimation of sex have been formulated from measurements of the skull [4][5][6][7][8][9] , pectoral girdle [10][11][12][13][14][15] , sternum [16][17][18][19][20][21] , pelvis [22][23][24] , hand and foot bones [25][26][27][28][29][30] with various degrees of accuracies. In addition, several studies have shown the usefulness of intact long bones of upper and lower limbs 13,[30][31][32][33][34][35][36][37][38][39][40] for sex prediction in different parts of the world.…”

South Africa has one of the highest crime rates in the world and the discovery of dismembered bodies for human identification process poses a greater challenge. The South African Africans (also known as South African blacks) population group is often the victims of crimes as they are the largest group. While measurements of several bones of the human skeleton have been used for sex estimation, the potential of metatarsals have not been explored in this population group. Metatarsal bones are usually well-preserved since they are recovered in shoes protected from scavengers and they are able to withstand environmental degradation and taphonomy. This study investigated the potential of measurements of metatarsals in sex estimate amongst South African Africans using logistic and discriminant function analysis. Six measurements of metatarsals from 100 individuals of known sex and population affinity from the Raymond Dart Collection of Human skeletons were analysed. Various combinations of measurements of metatarsal bones yielded suitably high average accuracies (79% to 84%) for sex estimation and are comparable to functions derived from other skeletal elements of South African Africans. Metatarsals of South African Africans are therefore useful as alternatives to highly sexual dimorphic bones in the forensic estimation of sex.

“…In recent years, computed tomography (CT) has proved to be a suitable tool for the estimation of sex (e.g., tali and radii, os coxae and sternum), providing reliable and precise results comparable to those obtained by the traditional morphometrics [15][16][17] . However, the number of studies that made use of the clinically relevant CT database to quantify the sex differences in the proximal femur and develop the accurate standards for that purpose is still low in the current literature 18,19 .…”

Background/Aim. The studies published in recent years have shown that the linear measurements on the three-dimensional computed tomography (3D-CT) clinical images of the hip bone, skull or breastbone can serve as a reliable alternative method for sex estimation. In spite of the fact that the proximal femur exhibited high dimorphism when examining the skeletal material, there is still a lack of morphometric studies dealing with the CT imaging of this anatomical region that would confirm the relevance of the previously obtained results. The aim of this study was to validate the reliability and precision of some proximal femur measurements obtained in vivo from the 3D-CT models and to compare the accuracies of our findings with those formerly reported by other relevant research. Methods. A total of 146 CT scans (73 male and 73 females) were selected to take 6 measurements using the traditional osteometric methods. The 3D reconstruction was done at 1mm and 1.25 mm thick slices with OsiriX (v.4.1). The univariate and multivariate discriminant functions (DFs) were formulated for assessing sex. Results. The vertical diameter of neck and the vertical diameter of head were found to contribute the most when considered independently (90.4%-91.8%). When combining these with the other dimensions, the prediction accuracy increased up to 97.3%. The accuracy of CT measurements is in accordance with those obtained in the traditional morphometric studies on the skeletonized femurs of contemporary populations. The 3D-CT approach showed remarkably higher percentage of predictive ability in comparison with the 2D technique. Conclusion. 3D-CT is a suitable tool for the objective quantification of osteological data. The medical scans and measurements on living individuals offer a valuable source of data from which the highly reliable skeletal standards can be developed for estimating sex, even from the fragmented remains. The method proposed here can be highly useful especially in the identification of mass disaster victims when the direct osteometry is difficult to apply and maceration of the remains is not an option.
