“…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.…”

“…towards females). Among sternal variables, the combined sternal length was found to be the best univariate DFA function, which correctly classified the sex of about 85% of sternums 39 . Males were comparatively better classified than the females from univariate DFA of individual sternal measurements, although sex biases were much higher than those calculated for clavicular variables.…”

“…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.…”

“…Torimitsu et al in Japan indicated a diagnostic accuracy varying between 62.5% and 84% in identifying gender. The researchers reported that measuring sternal indices could be an effective method of gender identification among Japanese bodies; in many cases, it is bet- ter than other predictive factors, like the pelvis bone and skull [17]. Ekizoglu et al conducted a study in Turkey [18].…”

Background: Identifying identity in the absence of large bones becomes more difficult and complicated; accordingly, it is highly beneficial to use the features of the sternum. The present study aimed to evaluate the dimensions of the sternum and its relation with gender in the Iranian population.Methods: This cross-sectional study was conducted on 200 cadavers (100 men and 100 women). By performing an autopsy, the sternum bone was first cut in the midline using a vibrating saw, and the different dimensions were measured using a caliper.Results: Among different dimensions related to the sternum, the mean length of manubrium, mesosternum, the largest width of manubrium, and the shortest width of manubrium were significantly higher in men compared to women. Regarding the value of each sternal diameter in discriminating male and female gender, the highest discriminative value was specified to the shortest width of manubrium (cutoff: 26.75, sensitivity: 100%, specificity: 84.0%), followed by the length of sternebrae 1 (cutoff: 8.45, sensitivity: 76.0%, specificity: 21.0%).Conclusion: Measuring various indices of sternum bone, particularly the shortest width of the manubrium and the length of sternebrae 1, leads to gender identity accurately.

Determination of sex on the basis of hyoid bone measurements in a Japanese population using multidetector computed tomography

et al. 2017

Sex determination for unidentified human remains is important because the determined sex is usually used as a foundation for the estimation of other biological profiles. This study investigated the sexual dimorphism of the adult hyoid bone and developed discriminant equations to accurately estimate sex in a contemporary Japanese population using measurements on two-dimensional computed tomography (CT) images. The study sample comprised 280 cadavers (140 males, 140 females) of known age and sex that underwent postmortem CT and subsequent forensic autopsy. In accordance with previous studies, seven measurements were performed using two-dimensional CT reconstructed images. Most measurements of males were significantly greater than those of females. The perpendicular length from the most anterior edge of the hyoid body to the line that connects the most distal points of the greater horns of the hyoid and the linear distance between the most lateral edges of the hyoid body most significantly contributed to sex determination. This study demonstrated that discriminant functions on the basis of three measurements provided higher rates of accurate sex classification (93.3-94.6%) than univariate functions. Therefore, the hyoid bone is highly sexually dimorphic in the contemporary Japanese population and may be useful in forensic contexts for sex determination with a high level of accuracy.
