Ben-Amotz said Apollo's surgery, which he hopes to complete in the coming weeks, is unprecedented. First, several CAT scans were done, and they helped create a 3D image of Apollo's elbow. That image will soon be sent to a 3D printer that Ben-Amotz and his team can study as they prepare for the actual procedure. Then, 3D cutting guides will be developed to be used in the operation, something that's never been done for elbow surgery in veterinary medicine, he said.
