Drage Josevski was diagnosed with Chordoma, a rare type of bone cancer, which grew in his spine. Dr. Ralph Mobbs of the Sydney Spine Clinic turned to medical device company Anatomics seeking help with this case, which finally produced 3D printed titanium implant that would replace the cancerous vertebrae. The operation took 15 hours and was successful one.
