PFFD VSG2

I am 54 and found out 2 weeks ago that what I have had all my life is actually called PFFD. I was hospitalised at 15months old for 7 years at Chailey Heritage in Sussex. I had a bone graft at 3years old ( which I understood later had not worked). I was allowed to get a contraption strapped to me that let me walk at the age of 7 or so.
Once freed from a bed I was very active. I went through various types of supports. My PFFD, (I am not up to speed on all the terminology yet) is on my right leg with a femur length of maybe 2'' , its a guess because I have never been shown an x-ray. I had a Symes amputation when I was 16. The foot was perfectly formed and was actually quite an aid to walking as it gave a more positive feel to the direction my artificial foot was pointing in.
I played a lot of sport (that didn't need running over long distance) and could hold my own in a fierce game of volleyball.
