(a) Five points determined by equidistance were marked along the length axis (AG) and 3 along the transverse axis (E’E”) to determine the planes to measure the horizontal and vertical radii (B’B” - F’F” and H’H” - I’I”), (b) for the humeral head 5 points determined by equidistance were calculated for both the length (KQ) and transverse axis (RX) to determine the individual planes where radii were measured (L’L” - P’P” and S’S” - W’W”).
