Posttraumatic Proximal Radioulnar Synostosis after Closed Reduction for a Radial Neck and Olecranon Fracture

Figure 2

Left elbow radiographs one (a) and two (b) weeks after injury. One-week AP and lateral radiographs (a) are partially obscured by splint material but demonstrate radial neck fracture with less than 30° of angulation (solid arrows in (a)) and a nondisplaced olecranon fracture (hatched arrow in (a)). Splint was removed and cast placed at one week. Two-week AP and lateral radiographs (b) are partially obscured by overlying cast material but demonstrate no changes from prior radiographs.
