There's no actual bone in the "sword" so it's not a fracture in the sense that it is a broken bone, which is why I was yelling at Lexie when she told Torres that Mark "broke a bone". And that's really not a surgery for an orthopedist to do, it should get fixed by a urologist, but this is GA, so anything can happen. It is however a rupture in the part that helps him "maintain his sword".
BTW, I read an article that after that episode aired, the name of Mark's injury was the #1 and #2 most searched terms on google.
This whole Izzy/Denny story just has to go already. Honestly, I can't imagine her thinking it's normal that Denny came back. If it were me, I would have gotten my brain checked soon as he showed up. And what about George? He hasn't been on much at all lately. And really, all those interns watching Mark's surgery?? I would have insisted that they close the gallery, since it's a superior with his stuff on display. Really, do you think any of them will be able to look at him the same way after seeing his personal stuff? It's bad enough that they all know he was messing around with somebody in the hospital, but really, it's a little too personal of an operation.
