An inhabited Chicago
Dante Autullo, 34, was in his workshop when a nail gun jumped back near his head.
But he had no plan the nail had gone into his brain until the next day, when he started on feeling nauseous.
Doctors told Mr. Autullo that the pin came within milli-metres of the area utilized for motor function.
His fiancee, Gail Glaenzer, told the Associated Press on Friday that he was in fine strength of mind after the two-hour surgery to eliminate the nail at Advocate Christ Medical Center in Oak Lawn , Illinois
"He suffers well. He moved all his limbs, he's talking routine, he memorizes everything," she said. "It's astonishing, a miracle."
Ms Glaenzer said she had no thought the nail had gone into his skull when she cleaned a cut on his forehead.
She persuaded him to go to the hospital after he felt upsetting for much of Wednesday.
Mr. Autullo considered that the nail gun had just hit his forehead, but understood later that when the gun came in connection with his head, the sensor recognized a flat surface and fired.
As there are pain-responsive nerves on a person's skull, there are nothing within the brain itself.
Hospital spokesman Mike Maggio said the piece of the skull that was eliminated for surgery had to be restored with a titanium mesh amid doubts that it might have been infected by the nail.
