Can I sue a nightclub for injuries brought on by bouncers?

The other night me and a bunch of my family and friends went out to a club to celebrate a high school reunion. My sister in laws ex was there and was continually haring her. Four of us on different occasions went up to the bouncers and asked them to please kick him out of the club. They simply ignored us. We decided we should leave and myself and 3 of us started out the door, before we got out the door we heard yelling and we turned around and I saw my sister in law get hit by her ex who then broke a gl bottle and cut her arm and threw her to the ground. I quickly ran over to pick her up and get her out of there cause it was clear she needed medical attention. My husband proceeded to attack her ex for hitting his sister. The bouncers pulled him off of him and walked him out the door. He asked the bouncers to please call an ambulance for his sister and the bouncer told him to shut up and threw him against a wall. I was still inside at the time and went over to pick her up to get her out of there and a bouncer grabbed me from behind and threw me into a table, I then got up and he pushed me back down over the stool (which was now laying on the floor). I told him I am just trying to get my sister she is hurt. Then he and 3 other bouncers sprayed the entire club with mase. I got myself and sister in law out the doors of the club and then 2 bouncers were throwing out her ex and threw him on top of me. I have a sprained wrist, and back injuries. My sister in law needed stitches and had a broken arm, and my husband had a dislocated shoulder (from the bouncer throwing him into the wall when he simply asked them to call an ambulance). He may need surgery we are not sure yet he has to see an orthopedic surgeon. Do we have a case against the bouncers of this nightclub?
