High Dj,
First of all when there is something broken above the ground you can support all branches that are damaged or broken. You can use sticks (I like to use chopsticks) for support and binding wire to bind everything together. Open wounds can be fixed with tape (The good old ductape).
And for everything under the ground. When a part of your roots are damaged you should treat her like a clone with high humidity and the light not to close and to strong.
I think that she will be ok. After traumatizing they look really sad (might even become a lot worse in the next few days) for the first few days. But when she start to recover she will recover really fast. Cannabis is a strong plant.
Goodluck bro! 😋
