Example images of 3D reference points. a An example image for each reference point. Left row images show the reference points in the preoperative plan image. Right row images show the reference points in the postoperative image. The light blue bar indicates the long axis of the distal radius. Red dots indicate the radial styloid process: reference point (1), the sigmoid notch volar edge: reference point (2), the sigmoid notch dorsal edge: reference point (3), and the barycentric coordinates. b An example image for 3DVT and 3DRI. The angle between a connecting line from reference point (2) to reference point (3) and a line perpendicular to the longitudinal axis of the radius was measured as the volar tilt on a 3D image in the sagittal view (3DVT). The angle between a line from reference point (1) to reference point (2) and a line perpendicular to the longitudinal axis of the radius was measured as the radial inclination on a 3D image in the coronal view (3DRI). The measured angles in the example image were 19.2° and 12.7° for 3DRI and 3DVT, respectively
