Thank you for your wishes dear friends!
I meanwhile have new plaster and am alowed to stand on the leg/ankle, but I can't walk yet! It's better to give it a bit rest. January 13th, I need to go to the hospital again and when pictures show that everything is alright, the plaster might be re-moved and I can walk again.

Haha, WM breaking one ankle is enough!
