Illustration of the method used for: a CSA measurement: The mesh is placed in the baseline position a manipulated until a Suter-Henninger A1 view was achieved. A 2D angular measurement of the CSA is then performed; b Glenoid inclination: The mesh is manipulated to the baseline position; the glenoid inclination is the angle between a line running from the superior to the inferior margin of the glenoid and the z-axis; c Glenoid version: The mesh is placed in the baseline position. It is then rotated about the point C until there is optimal overlap between the anterior and posterior glenoid rims. The angle of rotation of the mesh required to achieve the A1 view defines the glenoid version (in this case 3°)
