I'm 16 months down the line after fracturing and dislocating my ankle. Went through elbow crutches, wheelie zimmer frame, walking sticks to name a few aids and admit the crutches were the most helpful, although it took a lot of determination to get used to them, building up walking on them every day, increasing the amount of steps taken was my only solution.
Now my back is very painful on the 'broken side' when walking but I'm pretty sure it's because I'm still not totally mobilised, I had pins and plates inserted but muscles and nerves round the ankle haven't gone back to normal plus I've put on a lot of weight - which I think's the cause of the back pain. My other ankle's come out in sympathy!
Regarding the back pain, I find having a cushion supporting that area when sitting helps and also a heat pad can help short term.
I'm interested to see how others have coped with this as I'm planning to go to my GP this week to see what she suggests.
