AFFs also occur in adolescents treated with bisphosphonates during childhood.
AFF is for the first time reported in X-linked osteoporosis due to PLS3 mutation.
A genetic predisposition may underlie AFF at least in some cases.
Bisphosphonate-associated fractures may occur in other long bones beside the femur.
The occurrence of AFFs should be considered in management of congenital bone disease.
