From: Measurement of acetabular inclination and anteversion via CT generated 3D pelvic model
a Conception of Inclination and Anteversion in three different measurements of pelvic region.AO was pivot of the pelvic region; OE was longitudinal axis. The projection line of AO on sagittal plane was OB; OD was a projection line on coronal plane and OC was a projection line on transverse plane. b Anatomic Inclination (∠AOE) and Anatomic Anteversion (∠COF). c Operational Inclination (∠AOB) and Operational Anteversion (∠BOE). d Radiographic Inclination (∠DOE) and Radiographic Anteversion (∠AOD)
