You can apparently lay most dendrobium canes down flat on a growing surface and they'll then sprout/"keiki" from the nodes. This might help you deal with some of the unwieldiness, but in due course, they'll be 2' monsters again.
I have a Dendrobium moschatum that grows ~3' long canes that keep leaves for a year and then drops them and does little else. This is the last year it gets to do anything useful (like flower) before it gets rehomed/binned, because it's far too big for my balcony area.
