Is it the screw or needle plate that's broken? If the head of the screw is ok you can try a couple gentle taps on the end of a well fitted screw driver. Sometimes that will be enough to break the bond loose so you can back the screw out. Go gentle. You don't want to break the cast iron machine it's in.
