I believe I may be the oldest PFFD and that most of the original work was done on me at the Children’s Hospital , Boston (Brookline), MA (now known as the Children’s Medical Center) under Dr William T Green who was Chief Orthopedic Surgeon of the Children’s Hospital and full professor in Orthopedic surgery at Harvard Medical School. His pup and protégé was Dr David Grice.
I was diagnosed (in 1931) as, in those days, a Congenital Absence of the proximal 2/3 of the femur and acetabulum, acute (today known as a PFFD). There was a girl with a similar diagnosis but she died at age 12.
