I don't know much about it. My doc mentioned it early after my calcaneous facture. I though it was just a brace.
As far as two months on crutches, it sucks, I spent 3 in a wheel chair then walker. But it goes by. I found the walker more stable then crutches. If I had to do it I would probably do it in the spring, after winter, but heal in time for summer.
Hi, my husband's ortho recommended the Arizona brace after he shattered his heel bone and also has subtalar joint damage. He has chosen not to use the brace so I can't share his experience there, but I can share this. You are wise to avoid surgery if at all possible. My husband was 49 at the time of his first surgery, then had another 6 months later. He is healthy, fit, trim, lifetime non-smoker, no illnesses, etc. and he still had extreme difficulty with healing. In fact his delayed healing caused a bone infection, doing further and more extensive damage to his joint than the original fall did. So you are wise to try other options before surgery - I wish you the best!
