Saving a Climbing Ivy?

I have an ivy that I have grown in my bathroom for many years, it had climbed the wall and had great big leaves. My husband accidentally hit the stem with the door. I found the damage when I noticed the leaves seemed wilting. I cut it at the damaged part, pulled some of the climbing fingers off the wall and replanted it. Do you think it will survive? Or do I need to cut it down completely?
