“Utilizing CT Tibial Measurements for Stature Estimation and Age/Sex Identification in Egyptian Sample”

Background: Determining a person's height and body composition is regarded as a crucial identification step, and it becomes very challenging when dealing with mutilated bodies or skeletal remains. The length of the long limb bones is used to indirectly calculate height. The calculation of living height, which is predicated on the idea that an individual's height and bone length have a linear relationship, can be a crucial research tool. Aim: The purpose of this study was to evaluate the precision of stature identification using computed tomographic images from various tibial measurements. Methodology: In this observational cross-sectional study, 200 living Egyptians in the Aswan Governorate were subjected to spiral computed tomography of the Tibia between September 2019 and June 2023. Results: the stature ranged between 155 to 183 cm with mean of 164.81 ± 6.9, while there were 117 patients (58.5%) with short stature 165 cm. There was significant age and sex difference in the different investigated diameters (AB, CD and EF), with p-value (p < 0.001). The most accurate distances were A-B, E-F, and C-D, in that order. The C-D distance is the most sensitive in terms of sensitivity, followed by the A-B and E-F distances. The distance between A and B had the highest specificity, followed by E and F and finally C and D. Conclusion: An equation for estimating a person's height based on tibia length was presented in the current study. Hence, the present study produced promising results that can be used in a forensic anthropological context.
