Application of 3D geometric morphometrics in the study of the anatomical joint of talus and calcaneus in skeletal remains in forensic context
Summary:
Forensic anthropology is the scientific study of human skeletal remains in medico- legal contexts. A forensic anthropologist can assist in many cases and especially in the identification of commingeld human remains. This study is dedicated to such cases and is providing a solution to the identification issue in commingled context using the method of Geometric morphometrics. Geometric morphometrics has become a rapidly evolving method in Forensic anthropology, with the utilazation of which the diversity of the shape of the bone is studied based on the Cartesian coordinate system. Tali and calcanei of 25 individuals from the Osteological Collection of the Forensic Anthropology Unit of the Medical School at the National and Kapodistrian University of Athens were used in this study. Small and compact bones like those are highly resistant in taphonomic change and usually found intact in the field. The sample was scanned by a handheld 3D scanner and its articular surfaces were isolated with the assistance of the Meshlab programm. Furthermor, 13 landmarks were placed and examined using Geometric morphometrics in R software. Finally, the results were promising, as there was a successful assembly and therefore a posistive individual classification with this method. Ηowever, further research on the proposed method is necessary, in order to apply Geometric morphometrics in commingled contexts.
