Just a really quick update. Mom went to surgery about an hour ago (about 2:30). They're working on the left tibia, and will thoroughly clean the right tibia as well. They said it could be 3 - 6 hours before they are done.
Before they took her back, she was much more responsive. She's trying to mouth things to us (and she gets very frustrated when we don't understand), squeezing our hands, moving her toes. All really good signs. I figure she'll be pretty sleepy tonight and most of tomorrow. I don't know when the next surgery will be.
I'll let you know when she's out of surgery!
