A
Proximal radioulnar joint (PRUJ) dislocation
B
Scapholunate ligament dissociation
C
Distal radioulnar joint (DRUJ) dislocation
D
Ulnohumeral joint dislocation
Explanation:The correct option is 'c'. A Galeazzi fracture-dislocation consists of a fracture of the distal third of the radial shaft associated with a dislocation or subluxation of the distal radioulnar joint (DRUJ). Because of the deforming forces of the brachioradialis and pronator quadratus, these are highly unstable injuries that mandate open reduction and internal fixation in adults.
