摘要：The aim of this study was to specify the predictors of the narrowest pelvic diameter in females and males. Possible common tendencies and sexual dimorphism in this prediction are in question for measures in live humans. In addition, the relationship between the false pelvis and the true pelvis was not explored in males. The research sample included 211 females and 181 males, who underwent the computer tomography examination in the Hospital Gailezers, Latvia. Three-dimensional pelvic images were used for 12 linear measurements (8 diameters of the pelvic cavity in four pelvic levels, conjugata diagonalis, and 3 diameters of the false pelvis). The results demonstrated that the most powerful predictors of the bispinous diameter are the transverse diameter of the inlet and the bituberous diameter. These predictors are significant for both sexes. Sexual dimorphism manifests itself in a greater number of predictors and higher variance explained by these predictors in females. There is no statistical evidence for an accurate prediction of the bispinous diameter based on the diameters of the false pelvis.
