“…The reliably of the method in forensic cases was tested by Lynnerup et al [16], who obtained good results looking at the X-rayed trabecular changes in the proximal femur of living individuals. Computed Tomography (CT) was used to assess the trabecular structure changes on the pubic bone [17], the auricular surface [18] and the proximal epiphysis of the humerus and the femur [19]. Micro-CT scan, CT and X-ray were compared in a quantitative study of the trabecular changes in the pubic bone [20].…”

Villa C., Hansen M.N., Buckberry J., Cattaneo C., Lynnerup N. AbstractWe analyzed the trabecular bone changes in the pubic bone (PB) and in the auricular surface (AS) of the ilium using 319 CT scans of cadavers to estimate the age. Although the sharpness of the trabecular structure decreases in CT images when soft tissues are present, we identified four phases for the changes in PB and five in AS; a juvenile trait in PB and a senile trait in AS helped narrow the age range. High correlation with age was identified for both sexes in PB (F 0.89; M 0.75) and in AS (F 0.85; M 0.71) used independently or combined (F 0.91; M 0.78). The old adults (> 60 years) could be evaluated with better accuracy and discriminated in several phases. We found low inter-observer error and low inaccuracy (about 6 years, mean for all age ranges). The method is robust with respect to slice thickness, display window and kernel within the tested ranges.

“…Ten years later, other researchers proposed similar approaches using pubic bone (Wade et al 2011;Villa et al 2013b;Lottering et al 2014;Lopez-Alcaraz et al 2015) and on other bones. The auricular surface was investigated by Barrier et al (2009) and Villa et al (2013b), and the proximal epiphysis of the humerus and the femur by de Froidmont et al (2013).

Evaluating osteological ageing from digital data

SummaryAge at death estimation of human skeletal remains is one of the key issues in constructing a biological profile both in forensic and archaeological contexts. The traditional adult osteological methods evaluate macroscopically the morphological changes that occur with increasing age of specific skeletal indicators, such as the cranial sutures, the pubic bone, the auricular surface of the ilium and the sternal end of the ribs. Technologies such as CT and laser scanning are becoming more widely used in anthropology, and several new methods have been developed. This review focuses on how the osteological age-related changes have been evaluated in digital data. Firstly, the 3D virtual copies of the bones have been used to mimic the appearance of the dry bones and the application of the traditional methods. Secondly, the information directly extrapolated from CT scan has been used to qualitatively or quantitatively assess the changes of the trabecular bones, the thickness of the cortical bones, and to perform morphometric analyses. Lastly, the most innovative approach has been the mathematical quantification of the changes of the pelvic joints, calculating the complexity of the surface. The importance of new updated reference datasets, created thanks to the use of CT scanning in forensic settings, is also discussed.
