question: Hi. I am a 40 year old female with avascular necrosis of the femoral head. I had a free vascularized fibular graft at Duke University Medical Center 10 years ago and am now again beginning to experience symptoms of AVN. I live in Northern Colorado and my follow up doctor moved away several years ago. I am trying to do a search to find a specialist in my area who has experience with AVN and am not coming up with much. Do you have any suggestions for my search- and if you know of any surgeons (top surgeons- anywhere in the U.S. ) who are known for doing THP on patients after a free vascularized fibular graft that would be extremely helpful. Thanks. Brandi b
