“Maybe I can be helpful. Had Mobi-C disc put in at C5-C6, however 1st surgery failed to remove bone spur sticking into my spinal cord. 2nd surgery took care of it. Recommend using Yelp or other online reviews of doctors. Effectiveness varies widely.” – 11:20 AM · Oct 17, 2020·Twitter for iPhone
The tech CEO came in and said he had a Mobi-C, which is a type of cervical disc prosthesis, previously placed in his C5-C6 segment of his spinal cord. He then revealed the shocking news that the first operation was actually a failure because it did not remove the bone spur that was sticking to his spinal cord.
He said after that the second operation was a success. Elon Musk is basically someone who does research before he suggests something and it is evident in his many interviews such as the one he specifically has with Jim Bridenstine of Everyday Astronaut, a popular YouTube channel and Twitter page.
