Hello, everyone. I am new to this group. My son, Denim has of course PFFD, bilateral Class C/D. He is 22 months old. We live in Oklahoma City and go to the Children's Hospital here and also to the Shriner's Hospital in Shreveport. I was reading where a physiatrist might be of help to us and was wondering if anyone could recommend someone. My son has no hip sockets and no femoral heads so it looks like lengthening is out of the question. He is doing really well crawling on all fours(hands and feet no knees).
