Mapping method of distal humerus fractures. a 3D image of distal humerus fracture in CT scans. b Major fragments were reconstructed in Mimics. c Model of left-sided humerus was mirrored to make the orientation match that of the right-sided humerus in 3-Matic. d The reconstructed fragments were reduced, moved, rotated, and normalized to best match the normal model of the distal humerus. e Fracture lines were delineated on the template
