Osteometric reassociation of commingled human remains from a modern Greek sample using bone elements of the craniovertebral junction

摘要

There is a high demand of osteometric methods to address the issue of commingled remains, however, the research in reassociating the crania with C1, and C1 with C2, as part of the craniovertebral junction, is limited. Reassociating crania with the postcranial skeleton can offer beneficial information for personal identification, as the cranium is broadly utilized for sex and age estimation. Moreover, cranium contributes to the facial reconstruction, a useful supplementary method for forensic identification. For this study, measurements were collected from 159 crania and 182 C1 and C2 vertebrae from the Athens Collection, representing adult males and females between 18 and 99 years. A reassociation method was produced utilizing osteometrics of articular surfaces. A supplementary sample of ten individuals was utilized as a test sample, originating from Athens Medical School. Seven equations were generated by simple linear regression analysis for the reassociation of the cranium to C1, and C1 to C2. The blind test results demonstrated that this method can be applied with 80-100% success. Overall, the results indicated that the produced regression models are a useful addition to the existing sorting methodologies, as they can be applied in mixed-sex and/or fragmented commingled osteological assemblages.
