A MAN born without thighs is one of only 25 people in the world born with the condition. Nathan Hrdlicka, 34 from Santa Fe, New Mexico, has bilateral PFFD (Proximal femoral focal deficiency) type D - which means his knee bones are directly beneath his hip bones. As well as being only one in 25 people with the condition, he is the only one in the world who is able to walk. Despite his condition, Nathan, is in a loving relationship with his girlfriend, Chelsee Stuart, 19 who is at least a foot taller than him. Due to the location of his knee bones, Nathan's height is 4ft 6in, however doctors have said he would have grown to be over 6ft 4in.
