Abstract:
We report a patient of Scapholunate (SL) injury in which radiography revealed obvious SL dissociation with dorsal intercalated segment instability deformity, but arthroscopy showed a SL gap of less than 2 mm. Radiographs of the uninjured wrist showed a SL interval of 3.0 mm and a SL angle of 80°. Preoperative magnetic resonance imaging showed low signal intensity in the proximal portion of the scaphoid and a mild SL gap on T1-, T2-weighted, and T2-weighted fat-suppressed images. Midcarpal wrist arthrography revealed a small amount of contrast media leakage through the SL interval. It was considered that incomplete ossification of the scaphoid mimicked obvious radiographic SL dissociation.
