The flexion angle (θ) of the prosthesis. This angle is measured in the sagittal plane between the longitudinal bone stub axis (BSA) and the frontal flange (FF). The double arrows are used for determining the orientation of the BSA. The angle γ between the neutral line of the femoral component (N) and the BSA is calculated by γ = θ − 7°
