Simple Mathematical Relations between the Acetabular Anteversion and Sector Angles

Abstract

Acetabular anteversion is an important parameter of the hip joint. It is measured at CT of the hip, as are the more recently introduced acetabular sector angles. These angles give information on the anterior and posterior support from the acetabulum to the femoral head. Some simple mathematical relationships between these angles are presented.
