“…Regarding stature estimation, CT techniques have been applied on the cranium, cervical vertebra, scapula, clavicle, sternum, metacarpals, pelvis, sacrum, and upper and lower limb lengths in various populations such as the Italian, Swiss, Egyptian, Turkish, Japanese, Chinese, Korean, and Nepalese populations . These studies provide abundant comparable data to look into the correlations of different skeletal elements for stature estimation.…”

Stature estimation methods for Danish adult population have generally relied on Trotter and Gleser's and Boldsen's regression equations that are based on the skeletal remains of recent war dead American Whites, Terry Skeletal Collection, and Danish archaeological medieval skeletal materials, respectively. These equations are probably not suitable for stature estimation in contemporary Danish forensic cases. Furthermore, because postmortem computed tomography (PMCT) is now routinely performed at Danish forensic departments, equations based on PMCT, rather than measurements of defleshed bones, are needed. The aim of this study was to develop new equations for adult stature estimation based on PMCT femoral measurement. Maximum femoral length was measured on the PMCT images of 78 individuals (41 males and 37 females) aged 23-45 years. The measurement accuracy was tested on dry bones, and all the measurements were included in the inter-and intra-observer analyses. Both analyses results demonstrated the reliability of the method and data. Comparison between the living stature of the individuals and the estimates based on the equations by Trotter and Gleser and Boldsen demonstrated the unreliability of the previous equations to some extent. New regression equations were then developed and validated on a different sample of 18 Danish forensic cases. Comparisons of all the equations indicated that both the sets of previous equations underestimated the stature in the new validation dataset. The new equations developed in this study provide a reliable alternative for stature estimation in modern Danish forensic cases.

“…The ancestry, sex, age, and height of the individual should be known to determine the biological identity in Forensic Medicine and Archeology (Chiba et al 2018;Karakas et al 2011). The estimation of the sex is the first step (Gaya-Sancho et al 2018;Torimitsu et al 2017;Zhan et al 2018). Osteometry standards vary depending on parameters such as genetics, environmental factors, and sex dimorphism associated with the profession and lifestyle in the estimation of the sex.…”

“…Generally, female bones and body size are known to be smaller when compared to males. The degree of the difference may vary within the same population or between populations and could lead to secular variations (Hemy et al 2013;Macaluso and Lucena 2014;Singh and Pathak 2013;Zhan et al 2018).…”

Background Sex estimation is vital in establishing an accurate biological profile from the human skeleton, as sex influences the analysis of other elements in both Physical and Forensic Anthropology and Legal Medicine. The present study was conducted to analyze the sex differences between the sacrum and coccyx length based on the measurements calculated with computed tomography (CT) images. One hundred case images (50 females, 50 males) who were between the ages of 25 and 50 and admitted by the emergency department between September 2018 and June 2019 and underwent CT were included in the study. Eighteen lengths, 4 curvature lengths, and 2 regions were measured in sagittal, coronal and transverse planes with orthogonal adjustment for three times. Results It was stated that the mean anterior and posterior sacral length, anterior and posterior sacrococcygeal length, anterior and posterior sacral curvature length, anterior coccygeal curvature length, sacral area, lengths of transverse lines 1, 2, 3 and 4, sacral first vertebra transverse and sagittal length measurements were longer in males when compared to females (p < 0.05). It was noted that the parameter with the highest discrimination value in the receiver operating characteristic (ROC) analysis was the sacral area (AUC = 0.88/Acc = 0.82). Based on Fisher’s linear discriminant analysis findings, the discrimination rate was 96% for males, 92% for females and the overall discrimination rate was 94%. Conclusions It was concluded that the fourteen parameters that were indicated as significant in the present study could be used in anthropology, Forensic Medicine and Anatomy to predict sex.

“…Univariate discriminant analysis revealed that APD was the best for sex determination with (67.1%) accuracy then PSL (65.8%) and PSCL (64.6%). Zhan et al (2018) evaluated some sacrum and coccyx parameters by multidetector computed tomography for estimation of sex in Chinese population and reported that the stepwise analysis of all used lengths gave a sex determination with 84.9% accuracy and a sex bias of 3.7%. Torimitsu et al 2017analyzed postmortem computed tomography images of 230 Japanese corpses and reported significant sex differences in PSCL and PSL, with 77.0% accuracy in univariate discriminant function analysis.…”

“…The Research comprised of four spin echo sequences; a coronal localizer with repetition time and echo time (TR/TE) of 400/15 msec, a sagittal view with a TR/TE of 300-600/11-23 msec, an axial view with a TR/TE of 700-900/11-15 msec, and a sagittal view with TR/TE (dual-echo sequences) of 2500-2600/16-21 & 90-105 msc. Seven length measurements and two angles were performed as reported by (Torimitsu et al, 2017;Zhan et al, 2018;Etli et al, 2019). They are summarized in (Table 1, Figure 1, 2).…”
