A wall fell on him.
Generally when there is blunt trauma, there's all sorts of nasty hemorrhaging and disgusting crap that accumulates inside the newly-torn body cavities, and the pressure from that can sometimes lead to further injury (if something is keeping it all in, like, say, a skull) or just extreme discomfort and a long healing process that is susceptible to infection.
Just be happy it didn't happen to his brain, they would have had to drill a hole in his skull to reduce the pressure. Be even happier that he wasn't a caveman, they found one out there who had that surgery performed on him. With no anesthetic. And a pointy bit of rock for a scalpel.
