Abstract

Estimation of stature is a basic and important forensic procedure in identifying decomposed or skeletonized bodies. Due to advances in radiologic equipment, forensic science frequently uses computed tomography (CT) and software to apply these findings to investigations. Technical developments have increased the accuracy of the measurement of various bones. However, there are still some inaccuracies, such as defining correct landmarks in three-dimensional (3D) images. Femur length is frequently used for calculation of stature, but because it is a 3D structure, the digital image may not always correlate with the femur length measured with an osteometric board. However, more studies are now showing that the maximum femur length calculated in 3D imagery is comparable to the maximum femur length calculated using an osteometric board. This study used digitalized data of the femur obtained from the CT image through the specialized software. The digitalized femur images were put on the virtual osteometric board, which helped us to understand the anatomic characteristics of the femur and to confirm that the maximum femur lengths calculated in 3D images are similar to the results obtained using an osteometric board. These data were used to obtain a stature estimation formula for the Korean population.
