Expert ReplyCondition analysis:
I don't know what country that you are currently living, but you may want to try and get a second opinion from another orthopedic surgeon. Since I have no way of personally evaluating your son, reviewing those x-rays, knowing the exact location on the femur, etc., so I really cannot offer any patient-specific opinion.
Pediatric femur fractures can be very challenging to properly treat, especially in a two year old, so continue to be your son's advocate and insist that another orthopedist take a look at him.
