I can't so sure what's actually happen but might can be broken back or also can be a nutrition problem. (Like Beri-Beri in human case)
I would recommend to feed him enough with various nutrients specially Vitamin B and other vitamins.
His full stomache will also help to streach his spine straight again so feed him much as he can.
I've successfully treated similar case in WC bichirs that imported with curved spine like that.
Hope you get the best luck for him.
