My friend Gina, you see her commenting here all the time, has a son who was hit by a car this morning while catching his bus. They know he has a broken femur, and were still checking him out when she talked to the doctor last I heard. ETA: He seems to be ok other than the broken leg and being shook up.
This family is going to be in for a long haul.
My oldest son Jacob broke his femur skiing 3 winters ago. It was a year before he had his last appointment with a physical therapist. Sometimes kids have to go to therapy and learn to walk and strengthen the leg again. I think it depends on how the leg is set again and how long the person is unable to walk.
Jake had a wheelchair for several months to go around school in. I had to pick him up every day from school because there was no bus to take him and his wheel chair.
I pray you have a short recovery C!
