Ella's follow-up appointment with the orthopedic surgeon went really well.
He told us that what happened is called an "incomplete fracture" since there is no actual crack, the femur just bent a little. Fractures and "bends" are a little more common for children with SMA, as their bones are not as dense due to limited weight bearing.
Anyway, she didn't need a cast and she was able to take the ace bandage wrap off! She just needs to take it easy for the next 4 weeks. The only way she can make the injury worse is to bang into the same knee again, so we keep reminding her to slow down in her power chair :)
Thank you all so much for your kind words and prayers for Ella!!
