Exemplary printout images from the commercial available software (Materialize®) in a revision case of a 30-year-old female patient with an injury to the left elbow as a child (presumable a radial head dislocation with load transmission over the IOM and a concomitant fracture of the distal forearm, the injury was treated with temporary pinning from the capitulum through the radial head (“Wittsche Spickung”)). Clinically there is painful stop in supination at 0 °. a Simulation of the left radius, in blue the mirrored healthy right side is overprojected demonstrating a shorter and radial translated joint distal radius joint block. b Simulation of a radial extraarticular closing wedgen translation osteotomy stabilized with a virutal modern palmar locking plate. c Simulation of the left ulna with overlayed mirrored right ulnar showing a ulnarly directed malunion, and (d) matching the left ulnar after corrective osteotomy to the normal anatomy of the mirrored right ulna
