Hello. I'm Dr ChipWhat's your question please?
Did the x-ray show a fracture?
With a low vitamin D level the 9 month old's bones could be fragile
That said, yes having the 2 year old jumping on his arm could definitely have caused the fracture--it's not likely that it would have occurred without that kind of trauma
Please let me know if you need any more information
Yes--that would explain how the bone was twisted
No he wouldn't but I think it was the position of the 9 month old--with the arm twisted already--that caused the fracture
It could happen without any pulling on the arm
Yes--that's what must have happened
No--I'm sure the scenario we've described is what happened
