Dear Dr. Harley,
My 24 month old son has been diagnosed with Bilateral Congenital Radial-Ulnar Synostosis. He also has a bicuspid aortic valve and Chiari Malformation. We also have just found that my husband also has bicuspid aortic valve (he has not had an arm x-ray yet) and his grandmother had radial ulnar synostosis that was never "officially" diagnosed. No knowledge of any heart problems, but she is already deceased. There is obviously some genetic link here. We have seen a geneticist but have not found anything yet. Are there any syndromes you are familiar with that can encompass these problems? Possibly Holt-Oram?
My other question is regarding possible surgical treatment of radial ulnar synostosis. My son's arms are at about 85 degrees pronation. He is not able to supinate at all. In speaking with an orthopaedic surgeon, I was told that the main treatment option is derotational osteotomy. Is this an option you recommend? He is having some difficulty with use of silver ware, cups etc.
In my own research I came across another method that I am looking for more information on. Are you at all familiar with a technique to treat by Fuminori Kanaya involving a fat graft? The study was "Mobilization of a Congenital Proximal Radioulnar Synostosis with Use of a Free Vascularized Fascio-Fat Graft". I also found another study, by Dr. Neil Jones out of the Department of Orthopedic Surgery and the Division of Plastic and Reconstructive Surgery, University of California Los Angeles, "Treatment of radioulnar synostosis by radical excision and interposition of a radial forearm adipofascial flap". These techniques look like an interesting possibility and I am hoping to find a doctor who can give me more information about the success of these techniques and whether my son would possibly be a candidate for a surgery such as this.
Thanks for your help!!
Liz Holland
