Sex determination using discriminant analysis of upper and lower extremity bones: New approach using the volume and surface area of digital model

“…The volumes of the radius and talus, including damaged parts, have been examined in a previous study regarding sex determination [18], and there was no significant difference in the accuracy of sex determination between using a portion of the volume and the whole volume (80-90% accuracy). However, the presence of damaged bones may limit the direct use of the present method, because the total volume changes according to the volume of interest.…”

“…Accordingly, some studies have used 3-D scans of the cranium or the talus and radius to calculate their volumes for sex determination [18,19].…”

A test of Suchey–Brooks (pubic symphysis) and Buckberry–Chamberlain (auricular surface) methods on an identified Spanish sample: paleodemographic implications

“…This twentieth century collection includes 195 individuals (80\, 115_) ranging from 3 to 97 years of age. Demographic information, including age-at-death, was derived from obituary records (Rissech and Steadman, 2010;San Millán, 2011;Ruiz et al, 2012). Like most modern collections, the Madrid collection contains a high proportion of older individuals, reflecting increased life expectancy, lower birth rates and the marked improvement in general health (Rissech and Steadman, 2010).…”

Analysis of the three-dimensional anatomical variance of the distal radius using 3D shape models

“…A forensic study by Ruiz Mediavilla et al [7] avoided the bias of measurement location by assessing the volume of 127 distal radii (twentieth century) to analyze the potential of volume measurements in order to determine the gender of fragmentary remains. For the distal radius, they reported significant greater values for male and right radii compared to female and left radii respectively.…”

“…This is required to understand joint kinematics, improve fracture pattern analysis, plan surgical procedures [1, 2], design novel osteosynthetic devices [3–5], and identify human remains [6, 7]. Up to now, literature on the anatomy of the distal radius is limited to morphologic (shape) and morphometric (size) studies based on radiographs [8] or single computed tomography (CT) slices [9–11].…”
