title: The acetabular sector angle of the adult hip determined by computed tomography.
abstract: A new set of angles measured on standard axial CT images of the hip joint is defined. The angles provide information on the support of the femoral head from the anterior and the posterior part of the acetabulum. These angles have been measured in 82 adult hips, and correlated to a set of established parameters commonly measured at conventional roentgenography and on CT images of the hip joint. The defined angles may prove to be valuable in the total appreciation of hip joint function and stability.
