Introduction: Identifying individuals is one of forensic science's most difficult aspects. Accurate sex determination based on dimorphic dimension measurements in unidentified human remains is a critical first challenge towards identification of individual. Aim: to look into scapula sexual dimorphism. Objectives: to generate metric measurements for sex assessment in a Sohag community sample utilizing scapular metrics as maximum scapular length (MSL), maximum scapular breadth (MSB) and maximum length of spine (MLS) obtained from 3D CT images, aiming to meet the current demand for successful identification from skeletonized remains in forensic instances. Subjects and methods: the current study included 100 individuals (50 male and 50 female) who underwent thoracic CT (computerized tomography) scan examination as part of a pulmonary screening program. Images of each patient were analyzed and three parameters for both scapulae were measured. Results: The mean values increased by a statistically significant amount of the right and left MSL, MSB, and MLS in males in comparison to females. Conclusion: Among indices measured in the right and left scapulae, RT and LT MSL had the highest diagnostic accuracy while RT and LT MLS had the lowest accuracy in sexual dimorphism. Using CT scan, MSL, MSB and MLS were significant parameters in sex differentiation, Maximum scapular length in right and left scapulae was the most important parameter.
