Hi, This sounds quite similar to what I did (broke my fib and tib and dislocated my foot). After the short pot I had an aircast but was stil none weight baring for 3 months after my injury. I then had the bolt/large screw removed during a day surgery. After that I was told I could weight bare in the aircast once I wasn't so sore anymore. I felt fairly confident and could walk a few days after surgery. That was April and I can walk now although I don't have the full range of motion etc back yet. I can't run or walk quickly for a long period.

I don't know how the lack of blood supply will affect your recovery but you sound to be in a pretty similar situation to me. I kept my foot elevated as much as possible and that really helped with the swelling and stuff too.

Hope you get better soon
