Review Question - QID 219754

A 42-year-old female with a past medical history of rheumatoid arthritis presents to the clinic for continued management of her right wrist pain. She had been previously diagnosed by her primary care doctor with "wrist arthritis" identified on plain films. She has attempted immobilization, injections, and non-steroidal anti-inflammatories without improvement. When discussing the potential surgical options, the prospect of radiolunate or radioscapholunate fusion is discussed. What examination and radiographic findings would indicate the aforementioned procedures?
