They won't/shouldn't try to check them... there are no limits of liability on assistive devices so any scratch and they have to provide new, but that does you zero good sitting in a wheelchair in a jetway with a crutch bent in half.
On the CRJ-550 they might fit between cabins in the baggage cabinet on top of other items at an angle.
My husband travelled with crotches for nearly a year. Half of the time, the crotches fit in the overhead bin (preferred) and half of the time, next to the wall on the floor (some FA didn't allow this and best if you have window seat). Only once in a blue moon the crotches went into the closet (most inconvenient).
