A 35-year-old landscaper presents with pain on the ulnar side of the wrist 5 weeks after a fall at work onto an outstretched dominant right hand. Notable physical examination findings include isolated tenderness over the lunotriquetral (LT) interval, pain and excessive motion relative to the left side on lunotriquetral ballottement test, and a positive Kleinman shear test. Radiographs are normal.
