Measurement method of coronal inclination (CIF’, defined as the angle between the line through the longitudinal axis of the neck of the femoral component and the horizontal on the mechanical femoral axis) (a), sagittal inclination (SIF’ defined as the angle between the line from the center of the femoral head to through the middle of the femoral neck, in relation to the mechanical femoral axis) (b) and transverse version (TVF’, defined as the angle from the center of the femoral head through the femoral neck, in relation to the horizontal on the mechanical femoral axis, with the posterior condylar plane as distal reference) (c) of the femoral component on 3-D MIP constructed CT (mechanical femoral axis/horizontal displayed as dashed line).
