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

Figure 5

Left elbow CT scans (a–c) and CT 3D reconstruction (d–f) at two years six months after injury. Axial (a, b) and sagittal (c) CT views demonstrate synostosis of the proximal radioulnar joint, as do anterior (d), medial (e), and lateral (f) CT 3D reconstruction views (solid white arrows in all). The radial head fracture is healed (hatched white arrows in (d)–(f)). U = ulna; R = radius; O = olecranon; C = cubital fossa.
