Recently far side of fifty http://farsideoffifty.blogspot.com/ left a comment about how she too had broke her ankle 30 years ago and was in a cast for months and months..had to learn to walk again and etc.
Today....they have hardware....plates, screws and etc. that allow you to get up way before the bones are actually healed.
and I am walking! It's slow and not too pretty but I am making progress. It really is amazing that it has been less than seven weeks since it all happened. These are the only shoes that I can get on and think I may need to buy some more Velcro type for winter since the Doc says swelling will continue for some time. I will have to be more style conscious next year:)
