Yep. I just got out of my cast last Tuesday. I broke mine in early March (6th or 7th).
I totally snapped my left arm in half. My wrist was underneath my forearm. I don't want to scare you, but I've had two surgeries because of it.
The first one was to fix my arm because of how ****ed up it was. There was literally a step in my arm, but with yours it's a V.
The second was because my bones started to mend at a 35* angle. They bent my arm back, and pinned it.
If you end up getting above the skin pins (if they have to, that is) it doesn't hurt when they pull them out (mine didn't, except for one out of the three).
That's all from falling backwards onto it. The first point of contact was my wrist/forearm, and I heard the two snaps.
It sucks. Hopefully you won't be in a cast as long as I was.
Best of luck to you
