I've fractured my right ankle twice. First in a motorcycle accident, in which my toes were pointing backwards (yeah), and the second time in a slip on the E ledges on the M Route. I walked out on the second one.
with the first, they told me they thought I'd be able to walk again, but not run....and they were right.
I had 25 good years, but the second seemed to accelerate the arthritis that was developing. I've lost a lot of range of motion, such that when I go up on a slope, my ankle doesn't bend sufficiently, and I have to carry my weight with my muscles, which exhaust quickly. Hiking involves significant pain.
My advice? Push your rehab, strengthen the soft tissues which heal MUCH more slowly than bone. Really try to protect the joint, additional injuries will pay major problems. Hiking poles used properly, will pay huge dividends. Don't hike without them.
