Figures 21, 22. (21) Anterior (a) and superior (b) volume-rendered spiral CT images obtained through a cast show a comminuted, impacted fracture of the distal tibia (arrows in a). (22) Lateral (a) and anterior (b) volume-rendered spiral CT images show a Salter II fracture of the distal tibia (arrows in a, solid arrow in b) with considerable anterior and lateral displacement and angulation of distal fracture fragments. The anterior view also clearly shows an associated fibular injury (open arrow in b).
