A graph shows the changes in pelvic measurements attributable to changing pelvic obliquity. The gray zone denotes measurements +/− 3° of the measurement at anatomic position. The dotted lines correspond to the amount of obliquity at which the corresponding measurement exceeds 3° from the measurement at anatomic position. AAI = acetabular anteversion referenced by posterior ischia; AAF = acetabular anteversion referenced by femoral head centers; AASA = anterior acetabular sector angle; PASA = posterior acetabular sector angle; HASA = horizontal acetabular sector angle.
