摘要：Since the human scapula exhibits sexually dimorphic features, ithas been examined in detail in recent years, especially in termsof direct anthropometric measurements. During theseinvestigations, only very few authors have used derived variable(area of the glenoid cavity) and they reported that thismeasurement could be used for estimating sex. However, otherareal variables of the scapula have not been studied to determinewhether they contribute to predicting sex. Therefore, we aimedto clarify the question of whether derived variables, as well asdirect measurements, could contribute to sex estimation. In thepresent study, four direct scapular measurements were takenfrom the magnetic resonance images (MRI) and we thencalculated two derived variables from 99 male and 105 femaleadults’ scapulae. Direct measurements are infraspinous fossaheight (IFH), maximum scapular breadth (MB), glenoid cavitylength (GCL), axillar bone length (ABL), and maximum spinelength (MSL). Derived areal variables are MB*IFH and MSL*IFH.Univariate discriminant function analysis yielded overall sexprediction success rates ranging from 82.4% to 67.5%. As a singlederived variable, MB*IFH, was the most discriminative for sexingthe individuals. Multivariate discriminant analysis yielded 90.5%success in correct sex assign by using three parameters (ABL,GCL, and MSL). These results demonstrate that the analysis ofscapular size provides a highly accurate tool for assigning sex.
