Age at death estimation is of major importance for the forensic scientist. Currently, various methods have used macroscopic osseous criteria for articular surfaces. Particularly in the pelvis, articular surfaces are used to classify bone evolution and age. The objective was to assess coxal bone computed tomography (CT) scan procedure to initially estimate adult male age at death and model this age using quantitative measurements.
The material used included 33 coxal bones obtained from adult males of known age. Samples were obtained from 27 males during forensic autopsies and the 6 remaining samples were collected by the Normandy Whole Body Donation Center. Criteria of all bone samples were measured by CT scan. The criteria were inspired by previous osseous anthropological methods for age estimation using coxal symphyseal, auricular and acetabular surfaces. Inter- and intra-reproducibility of each criterion was calculated. Then, correlation to age at death of the reproducible variables was calculated.
Correlation factors were used. These link CT scan criteria data to age at death. Reproducible criteria included in the analysis as reproducible and correlated to age were: auricular surface apex activity, symphyseal ventral rampart and acetabular fossa porosity.
The results suggest that research using CT scan criteria data could be a useful forensic tool to determine age at death.
死亡年龄估计对法医至关重要。目前，各种方法都采用了关节面的宏观骨骼标准。特别是在骨盆中，关节面被用于对骨骼发育和年龄进行分类。目的是评估髋骨计算机断层扫描（CT）扫描程序，以初步估计成年男性的死亡年龄，并使用定量测量对该年龄进行建模。
使用的材料包括从已知年龄的成年男性身上获取的33块髋骨。样本来自27名男性的法医尸检，其余6个样本由诺曼底全身捐赠中心收集。所有骨样本的标准均通过CT扫描测量。这些标准是受先前使用耻骨联合、耳状面和髋臼面进行年龄估计的骨骼人类学方法启发而来。计算了每个标准的组间和组内再现性。然后，计算了可再现变量与死亡年龄的相关性。
使用了相关因子。这些因子将CT扫描标准数据与死亡年龄联系起来。分析中作为可再现且与年龄相关的可再现标准包括：耳状面顶点活动、耻骨联合腹侧壁垒和髋臼窝孔隙率。
结果表明，利用CT扫描标准数据进行的研究可能是确定死亡年龄的一种有用的法医工具。
