Introduction: Differences of anatomical characteristics regarding side and gender have been the topic of interest in various recent studies. Studies have reported either significant or insignificant differences of the bony pelvis. The aim of this study was to evaluate possible gender and side differences of the pelvis in a cadaveric model. Material and Methods: Fifty human cadaver pelves, preserved by the use of Thiel's method, underwent measurement during this study. Diverse parameters were measured on both hemipelves by three surgeons. Analysis of the morphology of the acetabular cavity was performed by measuring its longitudinal, horizontal, and maximal diameters. Results: The distance between the anterior superior iliac spine and the posterior superior iliac spine (females: mean of 15.9 cm; males: mean of 16.9 cm) and the horizontal diameter of the acetabular cavity (females: mean of 4.5 cm; males: mean of 4.9 cm) were statistically significantly shorter in females than in males. The subpubic angle was significantly (P < 0.001) larger in females (mean 61.4°; standard deviation [SD] 11.02°; range 37°–82°) when compared to males (mean 45.5°; SD 7.48°; range 35°–60°). The vertical diameter of the obturator foramen was significantly (P = 0.002) smaller for the right (mean 3.1; SD 0.56; range 1.9–4.6) in comparison to the left side (mean 3.4; SD 0.57; range 2.5–5.2). Discussion and Conclusion: Overall, a clear gender difference was observed for typical gender-specific parameters, whereas the anatomy of the hemipelves showed no relevant side differences.
