A30-year-old man was referred for magnetic resonance imaging of a painful right wrist. He had been involved in a motorcycle accident several days earlier and had fallen onto his wrist. Fig. 1 is an axial T1-weighted image through the radiocarpal joint. Fig. 2 is a coronal T1-weighted image. Dorsovolar and lateral plain radiographs were subsequently obtained for correlation with the magnetic resonance images and are shown in Figs. 3 and 4.
From these images and radiographs can you make the diagnosis?
For the answer and discussion see page 307.
