Our son Jacob has PFFD Type B. He has had 3 superhip surgeries over the last five years, peformed by Dr. Paley at the Rubin Institute for Limb Lengthening in Baltimore Maryland to stabilize his hip. Jacob recently had his first lengthening surgery performed by Dr. Paley on June 15th 2007. Jacob is now recovering well and he is having physical therapy at the Rubin Institute's therapy department. Jacob was born with a hip that was not fully formed and a very short femur. Dr. Paley was the only doctor that would and could help our son to correct his hip first.
