She said she was trying to find the best way to get around in her current state; the walker had hurt her hands too much. I asked about crutches; she said she had tried those but they hurt under her arms. I told her that if her armpits were resting on the crutches, instead of hovering a couple inches above them, they were too long for her, a fact I think she had not considered. (Don't the ER folks try to fit these things any more?) Maybe I'll see her with crutches tomorrow.
I had a broken leg several years ago [1]. I was initially intimidated by crutches and handled the steps in my house while sitting (butt-slide down; crab-walk up; stayed off the banister :-) ) for the first couple days. I realized, though, that this doesn't generalize, especially outdoors in December.
Crutches turned out not to be that bad once I got used to them. By the end of this period of time I was, I think, far above average in proficiency. I once "ran" for a bus and was not much slower than if I'd had the use of both legs; the spectators on the bus were quite impressed. (My "stride" with crutches was longer than my regular stride, which made up for the basic inefficiencies in the form.) I could do steps easily, even on tricky surfaces. Snow was only a problem because of depth, not because of slickness. While it was a major cramp in my style that I could not walk while carrying an open can of Diet Coke, in most other respects the crutches were not a serious barrier to life. That really, really surprised me.
[1] I don't say "I broke my leg", because it was definitely not my action that led to that state. If you're going to run a red light while speeding (and with small kids in the car to boot!), you should at least look for obstacles like pedestrians.
