Again, I with her a quick and easy recovery. Also, as someone pointed out to me, it's hard on the parents too. Hang in there, we're pulling for you/your dd.
My dd's fractured her elbow earlier this month. Her fracture was not nearly as bad as what you've described but she felt the same way. I wonder if a variation of what I did for my dd would be helpful. (You've had some setbacks so it might not be as straightforward for you.)
I created a wall calendar marking when she had her accident. On the calendar (now on her wall) I'm marked off the date of her accident, all of the follow-up appointments and the dates for milestones (for example when she could get re-casted (she was looking forward to a pink cast), out of cast, when she will hopefully have her mobility back, strength, when she can return to her activities. For items that are a date-range I used an the mid-date (then if it's earlier I can tell her she's ahead of schedule).
I even stuck a few non-related items on her calendar (like a family vacation). It's been really helpful. Also, it helps to remind her how far she's come and that she's on the mend.
I'm not sure if this would help but would it be helpful for her to go to the gym to watch a practice or meets just to stay connected with her teammates?
