I'm new to this site and i just happen to be doing a little research on my PFFD. Trying to learn what is and just curious if there were other people out there like me. I'm 33 years old, I have Bilateral PFFD and really don't know to much about it. I also like alot of other people went to Shriners hospital. I started going there i believe around the age of 3. I am 4'10 my left leg is shorter than the other and of course i walk with a limp. i have a twin brother who does not have anything wrong with him.
