[Batman] So, I'm a normal guy forced in robbing a bank...

So, I'm forced into robbing a bank because the Joker has my wife hostage, Batman comes in to break up the heist and injures my back, My wife gets out of the hostage situation unharmed, with my injured back, I can no longer work.

My question is this: Does Batman get away with it and do i get any compensation due to the circumstances?

Assuming that the law in Gotham works generally like the common law / usual statutory law in the United States, you weren't likely going to be able to sue him successfully anyway. 

First, just because your wife is a hostage doesn't totally get you off the hook for your actions.  Yes, you might be able to use the justification excuse to get out of some of the criminal charges, but not if you, for example, killed somebody. 

Additionally, Gotham likely has a pretty generous law when it comes to the defense of others / property.  Assuming that you're robbing the bank with the threat of lethal force (holding a gun on the customers, saying there's a Joker Gas bomb in your vest, even if there isn't one, etc...) Anyone with the desire and the ability can come take you down without facing legal repercussions. 

Now, that's not true if they try to kill you. But everyone knows that Batman doesn't kill. He's using non-lethal force in the face of lethal force, and that gives him the edge.  To recover, you're going to need to argue that he was being negligent or acting outside of his legal rights, and it's unlikely that's going to be possible. 

Of course, he's acting as a vigilante, but that's not something you as the apparent criminal can use -- that's something the state can use to get him on criminal charges more generally, depending on how good the Wayne Enterprise "clean up the streets" campaign has done on lobbying to alter that law behind the scenes. 

And that's before the fact that in order to successfully sue him you'd need to know who he was and get him to submit to the jurisdiction of the court -- unlikely at best.
