We found out around 2 months old that one of my twin sons has pffd in his left leg. I have been doing a lot of research on this subject as we left the orthepaedic surgeon in our area with a lot of unanswered questions. We had a lot of questions answered through Dr Paleys website and we plan on seeing him in the future. We are planning on lengthening surgery when he is around 5 years old. We are trying to stay positive about his pffd but of course its a rare surgery and we are still concerned about him having to get the surgery as well.
