Thanks for the good wishes, everyone! I'll make sure to tell her to check her comments so she can receive them in person - well, as in person as one can, over the internet. Unfortunately I'm still in Nevada, so I won't be able to pass on your hugs (I wish I could), but her DH is taking good care of her and she told me not to come.
I did speak with her on the phone today, though. She's home from the hospital and already sounds a hundred times better than she did on Monday, before the surgery. Now that the bone is supported by the plate and pins she has much more mobility with the arm and isn't even in a cast - just bandages and a sling. She sees the surgeon again on this coming Monday. So things seem to be going well, and I have my fingers crossed that trend will continue.
