@McTag,
Mother is fairly well, though in the intensive care: due to her medical history (especially the strokes and her bad full blood count, they decided to do only a minimal operation, and just fixed the bones with a kind of ring, sewed another bone, which was 'wired' during the first operation some weeks ago.
The anaesthesists want her to stay until tomorrow in the intensive care.
She looks very weak, but also seems to have recognised me. (Couldn't speak due to the oxygen mask and the post-operative situation.)
All post-operative data (besides the blood) are as regular as expected.
I've talked with the operating accident surgeons as well as with the anaesthetists: both disciplines of the medical profession think that they could have done more (the surgeons) but considering the age and the general state of health of mother, they had to find a compromise.
We are very happy with it - and especially that they operation went well. (The nurses on the ward feared that something might have happened during the operation .... knowing mother since six weeks by now.)
