Abstract

The doctoral thesis "The sexual dimorphism and age-related changes of the lesser pelvis in human" is devoted to three main issues: sexual dimorphism concerning pelvic parameters' averages, their variances, and correlations among the parameters; prediction of the narrowest pelvic diameters; and aging tendencies in the pelvic architecture.Lesser pelvis parameters were detected for a sample of live human participants that constitute an essential difference from previous studies, which detected pelvic parameters on skeletal collections. As a modern method, the three-dimensional computed tomography (CT) provided a possibility for reconstructing of bony pelvis with individual width of pelvic joints and measuring lesser pelvic parameters in human.In order to assess sexual dimorphism of the lesser pelvis, pelvic diameters were detected in four slope axial planes at levels of the inlet, the acetabulum centers, the ischial spines, and the outlet. In addition, four pelvic angles were detected: pelvic inclination, sacral slope, subpubic angle, and sacral anatomical orientation angle.
