Analysis of acetabular version: Retroversion prevalence, age, side and gender correlations.

ABSTRACT:

Introduction

Studies using conventional radiographical signs and computerized tomography (CT) for retroversion of the acetabulum have reported a prevalence of up to 25%. The purpose of this study was to provide a detailed report on acetabular version, gender, age and side differences in a large cohort.

Materials and methods

A total of 404 patients receiving a whole-body CT scan, aged between 16 and 40 years, have been included in the study. The measurement was performed in the transversal plane on three levels: cranial, central and caudal.

Results

The retroverted acetabulum on all three levels had a prevalence of 0.25% (95% confidence interval 0-0.7%). The average central anteversion in men was 16.46° (±4.42) and that in women was 19.31° (±5.04) (p < 0.001). Version i
