An Australian neurosurgeon, Ralph Mobbs made a medical history when he successfully removed two cancerous vertebrae from a patient who is in his 60s and replaced it with a 3D-printed prosthesis. The amazing surgery was conducted late 2015 on a patient who suffered from Chordoma cancer, the tumor formed on his top two vertebrae. Without the surgery, the tumor would have compressed the brain stem and spinal cord, leaving him quadriplegic. Ralph Mobbs performed the 15-hour surgery that required him to separate and then reattach the skull to the spinal tissue with a new 3D-printed bone.
The neurosurgeon worked with an Australian medical device manufacturer (Anatomics) to print the replicas of the patient’s top two vertebrae out of titanium. Mobbs told Mashable Australia It was the first time in history that these two neck bones have been printed and successfully installed.
