Registration of three scapular landmarks (angular inferior, trigonum scapulae, and glenoid center) as fiducials before reconstruction. Scapular plane (green plane in the lower left image, green line in the upper left and lower right images): plane that passes through the three scapular landmarks. Axial plane (red plane in the upper left image, red line in the lower right and lower left images): plane that is perpendicular to the scapular plane. Sagittal plane (yellow plane in the lower right image, yellow line in the upper left and lower left images): plane that is orthogonal to the scapular and axial planes
