Well, update in order I think. Have a clinic appointment 20 April and if the X-ray looks good, the frame will be loosened. Basically they loosen the nuts so the whole assembly can telescope but can't bend. That way your new bone takes the weight but is still braced.
Then I will walk around with loose nuts (fnar) for a couple of weeks. Hopefully then followed by this thing being removed....
Really could do with this whole experience being over, TBH.
BUT: this is a cycling forum, you say. So to the cycling. Still on the turbo couple of times a week:
Yesterday was 40 minutes intervals, average around 220W. So some progress evident, I think.
