Pediatric Galeazzi fracture and dislocation

(A) View of the entire forearm of an 11-year-old boy with a Galeazzi fracture-dislocation.
(B) Close-up of the distal forearm shows that there has been disruption of the distal radioulnar joint (arrows). The distal radial fragment is dorsally displaced (apex volar), making this a supination type of mechanism. Note that the distal ulna is volar to the distal radius.
(C) In this second patient, the anterior posterior view shows some shortening of the distal radius (arrowhead) in relation to the distal ulna, which has a small greenstick component.
(D) The pronation component (arrowhead) is better appreciated on this lateral view. The distal ulna lies dorsal to the distal radius (dashed arrow).
