Q. ponytail palm lost it's top, bad shape
 

Last summer, we had a ponytail/elephant foot palm on the deck. Someone or
something pulled the top out of it. The top was laying on the deck. Now the
plant is inside the house, and not doing too good.
There is no new growth coming out of the top, and the growth that is there is
not looking good.
The other one that suffered no damage outside is doing great!
Is there anything that can be done for the sick one, or should it be pitched?
