Determination of Relationship of Scapula Morphometry and Gender by Computed Tomography

The aim of this study is to reveal the effective parameters for gender determination by means of scapula in Turkish population. In this study, morphometric measurements of scapula at computed tomography images of 60 male and 60 female were evaluated and their efficacy on gender determination were examined via stepwise logistic regression analysis. 10 parameters (scapular breath, maximum scapular length, supraspinous line length, infraspinous line length, trigonum superior border length, trigonum inferior border length, trigonum superior spinal length, trigonum inferior spinal length, medial angle, spinal axis angle) and 6 indexes (scapular index, supraspinous index, infraspinousindex, trigonum spinal index, trigonum index, supra-infra scapular index) obtained from these parameters were measured. As a result of statistical analysis, scapular width and maximum scapular length were found 85% effective in gender determination at right scapulae, 90% effective at left scapulae and 86.7% effective at all scapulae. No significant difference was found between right and left sides for the maximum scapular length, supraspinous line length, infraspinous line length, trigonum superior border length, trigonum inferior border length, trigonum superior spinal length, trigonum inferior spinal length, spinal axis angle, supraspinous index, trigonum index, trigonum spinal index, supra-infra scapular index measurements. Significant differences were found between men and women for the scapular breath, maximum scapular length, supraspinous line length, infraspinous line length, trigonum superior border length, trigonum inferior border length, trigonum superior spinal length, trigonum inferior spinal length, medial angle and spinal axis angle. The results of this study will contribute to the gender determination by means of scapula and surgical interventions of this region in Turkish population.
