Introduction: The imaging study of the morphometric characteristics of the hip joint, in a sample of asymptomatic cases, is important to understand variations from normality. Materials and method: This is a retrospective study on CT scans requested because of abdominal-pelvic pathologies, in both genders, aged between 18 and 45 years, orthopedi-cally healthy. A digital measurement of the acetabular version was performed. Variables considered and analyzed with descriptive statistics were age, sex and acetabular version. Results: 165 pelvises were included, 102 male (61.9%) and 63 female (38.1%). The mean age of the cohort was 36.4 years. The acetabular version was positive (anteversion) in 163 cases, with a mean male of 17.1° ± 2.7° (p <0.03) and female of 19.3° ± 3.9° (p <0.01). Two male pelvises presented retroversion (1.2%). The difference in the contralateral version mean was 1.15° ± 2.2°. Conclusion: The female acetabulum has a higher average anteversion than the male. Different contralateral acetabular anteversion is common. The prevalence of retroversion in an asymptomatic young adult sample is low.
