Plain radiographs of the left wrist showed a minimally displaced ulnar styloid avulsion fracture and a Salter-Harris III fracture of the distal radius involving only the dorsal ulnar corner which progressed from the dorsoulnar end of the distal radial epiphysis in the sagittal plane proximally into the physis separating the dorsal and volar ulnar rims and extending ulnarly through the physis and into the distal radial ulnar joint (Figure 1).
Sequential axial CT views (proximal to distal) demonstrating intra-articular extent of the fracture through the dorsal rim of the radial physis. (d) Shows the radial epiphysis fully in view, revealing the most volar extent of the fracture line dorsal to the volar ulnar rim.

CT scan obtained 6 weeks postinjury showed an intra-articular distal radius fracture along the dorsal rim of the radius that had largely healed, while the physis of the distal radius was shown to be narrowed and largely fused (Figures 2-4).
