Help! Broken DDS wrist joint

While posing my DDS Akira a noticed the joint on her wrist was sticking and the peg bit was coming out of the joint. I tried to pop it back into place, but that just made it worse. How do I fix it? I can't afford new arms for her.

 

Update: I've taken her wrist joints apart, and they look like they should just pop back together, but I'm still having issues trying to do so..

 

For images, please message me as I can't post images yet.

Do you get any help on this yet? Are you talking about the pin/peg that goes up into the forearm? I think that should be pretty easy to reattach. If you're talking about the actual wrist ball joint being broken, I don't think there's a simple fix for that.
