Résumé
Introduction
Identifying novel diagnostic parameters is essential to address the inaccuracies related to femoral head coverage angle measurements using conventional methods. This study aimed to propose new femoral head coverage landmarks on 3D pelvic CT images in a Korean population and to present reference values based on these landmarks.
Methods
This single-center retrospective cohort study defined the center, lateral, anterior, and posterior margins of the acetabulum from three-dimensional (3D) pelvic computed tomography (CT) scans of healthy Korean individuals. The lateral center-edge angle (LCEA), anterior center-edge angle (ACEA), posterior center-edge angle (PCEA), anterior acetabular sector angle (AASA), and posterior acetabular sector angle (PASA) were measured in 3D space.
