A Monteggia fracture-dislocation is best described as:
AFracture of the distal radius with DRUJ disruption
BFracture of the proximal ulna with radial head dislocation
CFracture of the radial shaft with distal radioulnar joint dislocation
DIntra-articular fracture of the base of the first metacarpal
Explanation: A Monteggia lesion consists of a fracture of the ulnar shaft (typically the proximal third) associated with a dislocation of the radial head at the radiocapitellar joint.
