Thank you for asking.
Four screws now removed from the foot, and apparently all has healed as it should. I have two new wounds, and must wear the air-boot for another two weeks. Then the stitches come out, and I will be signed off. I'm told I'll be walking properly in three weeks, albeit with a slight limp. The limp may hang around for a few months, but then I'll be back where I was last September, when the accident happened.
If anyone is remotely interested this is what happened
