#FlashbackFriday #DYK – In March 2005, Dr. Steven Cyr, former chief of Air Force spine surgery, successfully performed the Air Force’s first total-disc arthroplasty procedure. During the three-hour procedure, Dr. Cyr removed and replaced a failed disc in the back of an active-duty Tech. Sgt. with a new three-piece medical device consisting of two metal endplates of medical-grade cobalt-chromium alloy and a sliding core made of medical-grade plastic.
