Omuz Bölgesi Kemiklerinin Cinsiyet Tayini Açısından Morfolojik ve Morfometrik İncelenmesi

Abstract

Identification is the process of revealing the characteristics of living or dead people to distinguish them from other people by using their body remains. In identification, gender determination should be made after it is determined that the remains belong to a human being. It is often not possible to reach all the bones of the individual's skeleton intact. In this case, long bones are preferred for gender determination because they are more durable than other bones. The aim of our study is to investigate whether the humerus, scapula and clavicula bones of the shoulder girdle have a significant effect on sex determination. The sample of our study consists of 217 individuals, 113 male and 104 female, between the ages of 18-55, whose CT images were taken at the Radiology Department of Kırşehir Ahi Evran University Education and Research Hospital. Measurements in DICOM files were performed retrospectively by calculating centimeters (cm) and degrees (°) via the PACS program. A total of 17 measurements were taken from the images, 12 linear and 5 angular, and 2 proportional values consisting of these measurements were obtained. As a result of the study, the area under the ROC curve (AUC) for the caput humeri diameter and cavitas glenoidalis width variables were found to be statistically significant. When a cut-off value

of 4.16 cm was applied to the measurements of the caput humeri diameter variable, the observed sensitivity was 83.2% and specificity was 85.6%, while when a cut-off value of 2.78 cm was applied to the measurements of the cavitas glenoidalis width, the observed sensitivity was 82.3% and specificity was 90.4%. These values indicate that the caput humeri diameter and cavitas glenoidalis width variable can facilitate a sensitive, specific classification for gender determination and has significant diagnostic utility. In forensic medicine and anthropology, the fact that the upper extremity found separated from the body has a strong effect on gender determination will also facilitate the identification of the isolated extremity.
