Anatomical CT parameters measure the axial alpha angle (AA), femoral head-neck offset (FHNO) (A), radial alpha angle (RA) (B), femoral neck-shaft angle (FNSA) (C), medial proximal femoral angle (MPFA) (D), neck (NH) (E) and condyle horizontals (CH) (F) for femoral torsion, and acetabular version (AV) (G).
