Gasbagging recently put up some photos of a 5th Metacarpal shaft fracture (not quite technically a Boxer's Fracture).
It always amazes me that often these patients present with a typical story:
"I was ropeable. I was pumped up and about to hit someone... so at least I punched a wall (or a window) and not a person!"
What is it about them that they think they have to punch something? Why can't they contain their rage or vent it elsewhere (onto something soft)? As far as I can tell, there is about as much justification for punching a wall as self-mutilation. Oh, perhaps that is a topic for some other day.
