“…The present study found male acetabula to be larger in diameter than female acetabula, with a p-value of <0.001, deeming this result highly significant. This correlated with previous studies, which reported that males had a larger acetabular diameter than females (Chauhan et al, 2002;Zeng et al;Yugesh & Kumar;Rajasekhar et al). This finding was statistically significant in the studies conducted by Chauhan et al, Zeng et al, Yugesh & Kumar and Rajasekhar et al However, the finding was insignificant in the study conducted by Krebs et al (2009) on the acetabula of African-American and Caucasian people in America (Table V).…”

“…Marieb & Hoehn (2013) stated that in general, female acetabula are smaller and farther apart in comparison to male acetabula. Rajasekhar et al (2017) found male acetabula to be significantly larger in diameter than female acetabula. Furthermore, the acetabular depth was also found to be significantly larger in males than in females (Yugesh & Kumar, 2016).…”

The acetabulum is the large cup-shaped cavity on the lateral surface of the hip bone, which articulates with the head of the femur to form the hip joint. The morphometry and morphology of the acetabulum is important in the diagnosis and treatment of hip joint injuries and disease. Population specific differences exist regarding the acetabulum, therefore, this study aimed to document the morphometry and morphology of the acetabulum within a Black African population in Kwa-Zulu Natal, South Africa. A total of 100 dry hip bones (R= 44; L= 56) from the University of KwaZulu-Natal (Westville and NRMSOM campuses) were examined for this study. The hip bones, with documented sex, were all from the Black African population. A sliding digital caliper was used to measure the acetabular diameter, depth and acetabular notch width. The morphology of the acetabular margin was document in accordance with Govsa et al. (2005). Statistical analysis was conducted using SPSS version 24 software. A p-value of less than 0.05 was considered statistically significant. The means and standard deviations of the morphometric measurements for the entire population were as follows: (a) acetabular diameter of 54.84 ± 4.18 mm, (b) acetabular depth of 31.30 ± 3.18 mm and (c) acetabular notch width of 21.72 ± 2.98 mm. The observed shapes of the acetabular margin that were angular (41 %), curved (22 %), irregular (23 %) and straight (14 %). Knowledge of the anatomy of the acetabulum is useful to surgeons, prosthetists, anthropologists and forensic anthropology experts. The morphometry and morphology of the Black African population group of KwaZulu-Natal presented with differences when compared to other population groups studied in literature.

“…As shown in Table 4, the present study indicates that the cotylopubic length was of smaller value while acetabulum diameter was showing higher value in males when compared to corresponding values in females and found to be consistent with the results of similar studies. [13][14][15][16][17][18] The present study found out that the acetabulopubic index showed highest sexual dimorphism followed by of sexing when compared with that of Nagesh KR et al 23 in which accuracy percentage for sex determination was 17% with AP index of >88.4 in case of males, whereas in case of females, AP index <66.9 made out 26% of female bones.…”

The capability of determination of gender from unknown human skeletal remains is indispensable and the techniques to find out this from different bones of human skeletal remains have been researched tremendously. Several investigators have asserted the necessity for population specific statistical data for methods that are dependent on specific measurements as there exist ample variations in body size among diverse ethnic populations. Most reliable bone exhibiting sexual dimorphism in human body is the pelvis and we have chosen it for derivation of population and sex specific data with respect to diameter of acetabulum and acetabulopubic index. 72 adult, dry innominate hip bones without any morphological deformities and defects (38 of male and 34 of female sex) belonging to South Indian population were carefully studied with respect to diameter of Right acetabulum and acetabulopubic index derived from the maximum distance between pubis symphysis and the anterior rim of acetabulum i.e. cotylopubic length or acetabulum-pubis symphysis length. All measurements were accurately taken with the aid of digital Vernier caliper and results were analyzed by means of SPSS software version 26 and the results including the demarking point, standard deviation, sectioning point etc. were found to be statistically significant and therefore acetabulum diameter and acetabulopubic index can be authentically applied for sex determination from dry adult hip bones belonging to the South Indian population. From the analysis of demarking point, AP index of >94.13 identified 73.84% of male sex and <87.15 identified 84.97% of females and therefore AP index can definitely be considered as the positive and decisive indicator for sex determination from adult hip bones.

“…Sex determination based on skeletal remains is essential in forensic investigations and human identi cation after mass disasters, homicides, and accidents 1,2 . Manual morphological measurement and analysis of the skeletal remains are widely used to determine the sex of individuals [4][5][6][7][8][9]27 . In particular, the unique patterns of the frontal sinuses in males and females on CBCT scans make these sinuses an important and reliable tool for sex determination 16,20,34 .…”

“…Skeletal remains of the human body can preserve their shapes and structures even in harsh environments and disaster events, making them suitable for sex determination 3 . Manual morphological measurement and analysis of skeletal remains such as the hand bone 4 , hip bone 5 , teeth 6 , mandible 7 , skull 7 , and paranasal sinus 8,9 are widely used to determine the sex of individuals. These methods are based on the presence of signi cant differences in the sizes and shapes of the teeth, pelvis, and skull between males and females 10 .…”

Sex determination is essential for identifying unidentified individuals, particularly in forensic contexts. Traditional methods for sex determination involve manual measurements of skeletal features on CBCT scans. However, these manual measurements are labor-intensive, time-consuming, and error-prone. The purpose of this study was to automatically and accurately determine sex on a CBCT scan using a two-stage anatomy-guided attention network (SDetNet). SDetNet consisted of a 2D frontal sinus segmentation network (FSNet) and a 3D anatomy-guided attention network (SDNet). FSNet segmented frontal sinus regions in the CBCT images and extracted regions of interest (ROIs) near them. Then, the ROIs were fed into SDNet to predict sex accurately. To improve sex determination performance, we proposed multi-channel inputs (MSIs) and an anatomy-guided attention module (AGAM), which encouraged SDetNet to learn differences in the anatomical context of the frontal sinus between males and females. SDetNet showed superior sex determination performance in the area under the receiver operating characteristic curve, accuracy, Brier score, and specificity compared with the other 3D CNNs. Moreover, the results of ablation studies showed a notable improvement in sex determination with the embedding of both MSI and AGAM. Consequently, SDetNet demonstrated automatic and accurate sex determination by learning the anatomical context information of the frontal sinus on CBCT scans.
