My son is 20 months old and will be going to get a Super Hip 2 surgery done when he turns 2 years old. Not only does he have PFFD, his femur is growing at a 90 degree angle. So they will need to break his leg to straighten it out and then do the Super Hip 2. Dr. Paley did answer all our questions, so we are sure that he's the doctor to see about our son's condition. I guess we are just nervous about his surgery because he's our only child.
