The young man had been wheeled into Najma Ahmed’s emergency room with a bloody, penetrating wound to the chest. Whatever was inside had pierced his left lung dangerously close to the heart. His sternum was also fractured.
“It looked like a bullet wound,” said Dr. Ahmed, assistant trauma director at St. Michael’s Hospital in Toronto. But it wasn’t a bullet. It was a nail. It turns out that the man and a buddy had been playing around with a nail gun, and a 2½-inch stud had been fired accidentally into his torso.
