Ever since my left leg collapsed without warning and I broke my ankle, I have been terrified of another such event. My answer is to use a four wheeled walker thingy (at home & outdoors) I got @ Costco which folds easily and does the job. I've been considering a scooter and may well do it since walking, even w/ a walker, tires me out.

I'm not worried about the opinion of non disabled "civilians." I'm much more concerned about a fracture recurrence and all the disability that goes with it. My advice is to do whatever it takes to protect your limbs from harm. You don't want to risk compromising your independence even more by injuries/falls.
