Patient: This girl is Japanese, she was diagnosed with dislocation of both forearms in Japan, she lives with pain every day, and she is not willing to go on like this, she hopes to get good treatment in China. I am a friend of her father, and I am looking for a hospital and doctor who can treat her on her father’s behalf. I will send you the information about her medical history as soon as possible. Liu Qinghe, Department of Orthopedics, Beijing Chaoyang Hospital: I received 6 pages of information from you. The first 2 pages are about Noonan syndrome in Japanese, and the last 4 pages are 4 x-rays of bilateral elbow joints. The x-rays show that the patient has bilateral radial tuberosity dislocation. If there is no history of trauma, it should be congenital. The information given is very limited. Is it possible that the patient has other developmental abnormalities of multiple organs and systems that the Japanese doctor suspects to be Noonan syndrome? If so, a more detailed examination, especially chromosomal examination, should be done to clarify whether it is Noonan syndrome or Turner syndrome. In the above syndrome, treatment of other systemic disorders may be more important than the skeletal system. In the case of bilateral congenital radial tuberosity only, for this age, radial tuberosity resection can be performed if elbow extension and forearm rotation are affected.
