Are there a lot of things that can go wrong with the wrist, other than breaking it or something like that?
There are many disorders that can affect the wrist, from common diseases like arthritis to less common ones, such as Kienbock's disease. The wrist is made of very small bones and a small canal through which nerves go through to access the hand. If anything happens to any of the structures, the bone, ligaments, muscles, nerves, and soft tissues, you can end up with a good bit of pain and restricted movement and function of the hand.
