Review Question - QID 211941

A 54-year-old Bavarian baker presents to your clinic 5 years after undergoing a Radio-Scapho-Lunate (RSL) fusion for post-traumatic osteoarthritis of the wrist. He has persistent pain and significantly decreased range of motion about the wrist, particularly after a long day in the bakery or when applying his lederhosen. On exam, he has noticeably weaker grip strength and poor motion, particularly in radial deviation, compared to his contralateral wrist. A current radiograph of the affected wrist is seen in Figure A. What additional surgical step, performed at the time of the index RSL fusion, may have prevented this outcome?
