Immediately after this fall, he visited a local clinic, where non-union of the scaphoid was noticed, but the capitate fracture was overlooked on radiographs (Figure 1).

Radiographs and computed tomography (CT) showed non-union at the distal third of the scaphoid and at the middle of the capitate (Figures 2 and 3).
Computed tomography (CT) scan of the hand. Sagittal CT image of bone separation with osteosclerosis in the distal part of the scaphoid bone (a), and a radiolucent line in the central area of the capitate bone (b).

Radiographs and computed tomography (CT) showed non-union at the distal third of the scaphoid and at the middle of the capitate (Figures 2 and 3).
Magnetic resonance imaging (MRI) of the hand. T1-weighted MRI images showing proximal bone chips in both the scaphoid (a) and capitate (b) in high brightness. No impeded blood flow or necrosis was observed.
