Measurement of bone defect after simulating implantation acetabular prosthesis based on CT scan. a A-ASA = α and P-ASA = β are measured on the axial plane through rotation center. b The minimum thickness of acetabular inner wall is measured on the straight line passing through the rotation center. c S-ASA = γ and I-ASA = δ are measured through the coronal plane of rotation center. d On the same plane, the distance from the rotation center to the pubic symphysis (b) and the vertical distance (c) from the same point the horizontal plane of the lowest point of the ischial tubercle were measured
