After reading a recent People Magazine article featuring 2 young girls with PFFD, I finally learned the medical term for my Dad's shortened leg. I am thrilled to see a support forum for people with limb differences. When my Dad was born in 1918, no specialist had ever seen anything like his shortened right leg (his knee was essentially at his hip), and I am fairly certain that he never met another PFFD patient in his life. The doctors told his parents he would never walk, but he did, for 88 years.
