Confused...

So we met with the people from the Shriner's Hospital today.  I thought this appointment would be a simple step in the right direction. However, I am now more confused then before.  The doctor asked several of the same questions as Dr. S and he also had the same concerns and confusions with my Pie.  So this doctor is scheduling a normal appointment for Pie to meet with the Shrine's Hospital Peds / ortho doctor. But, he also wants us to meet with a genetics doctor. He feels that Pie might have a genetic disorder that is causing a perthes like reaction in her hips. He said he might be wrong but that what I had told him and the xrays being so symmetrical makes him feel that it is something more then just perthes.  I don't know what to think right now... I just know we will be on our way to Minneapolis again within the next month..
