This document provides information on Galeazzi fractures, which involve a fracture of the radial shaft with a dislocation of the distal radioulnar joint. It describes the mechanism of injury as a fall on a hyperpronated forearm, discusses associated injuries, signs on imaging, and classifications. Surgical management is the preferred treatment, involving plate fixation of the radial shaft fracture and possible pinning or open repair of the distal radioulnar joint if unstable. Postoperative immobilization and rehabilitation are also outlined.
