Review Question - QID 211402

A 28-year-old jack-hammer operator presents with 4 years of wrist pain. The patient was seen three years ago and had normal wrist radiographs at that time. The PA who saw him diagnosed him with a wrist sprain, and he subsequently returned to work. His symptoms never improved, even after a period of casting, so he was referred to your clinic after an MRI was obtained (Figure A). On physical examination, he has dorsal wrist tenderness and limited wrist extension. What surgical procedure may offer him the most reliable pain relief while best preserving the native anatomy?
