A PRELIMINARY STUDY OF SEXUAL DIMORPHISM OF SCAPULA BY COMPUTED TOMOGRAPHY IN THE MALAYSIAN POPULATION
Journal Title: Asian Journal of Pharamceutical and Clinical Research - Year 2019, Vol 12, Issue 1
Abstract
Objective: Sex estimation is one of the crucial steps for human identification, which is evident in cases of commingled, eroded, and/or missing remains. When pelvis or skull are unavailable, scapula has been used as an alternative bone for determining sex. Besides, the scapula was shown to be population-specific in several studies. Limited dry bone collections in Malaysia have led to various recommendations of virtual anthropology studies of bone in human identification. The aims of this study were to investigate the sexual dimorphism of the scapula using three-dimensional (3D) computed tomography (CT) imaging and to generate population-specific equations for sex determination in the Malaysian population.Methods: A total of 66 CT thorax images of 33 males and 33 females were taken. Morphological breadth (MB) and morphological length (ML) on bilateral scapulae were measured on 3D CT reconstructed images. Independent t-test and discriminant function analysis (DFA) were performed for analysis.Results: Results revealed that both parameters showed sexual dimorphism of scapula but displayed no difference between the right and left scapulae. DFA showed that MB and ML had high accuracy for sex estimation. The equations were highly accurate when both parameters were used in combination, followed by MB only and ML only, in that sequence.Conclusion: In brief, scapula measurements may be useful for forensic assessment of sex in the Malaysian population.
