Can I file a civil suit againsty estranged husband for tearing my rotator cuff?

Yes, you have to take action in New York. You can't take additional action due to his being an attorney, that comes into play later: if he is convicted of a crime, that could cost him his licence. That possibility might encourage him to settle up with you.

It should not be too late to press charges; and whatever your DIR is supposed to mean, it should not immunize your batterer from responsibility for physical violence. A civil suit would, most likely, have to be filed in New York. And the attorney's professional code of conduct is not directly implicated unless you were a client or an opposing counsel at the time of the attack; however, if you do press charges, and the case results in a criminal conviction - then your husband's professional license will be affected.
