BACKGROUND: Fractures of the radial shaft with disruption of the distal radial ulnar joint (DRUJ) or Galeazzi fractures are treated with reduction of the radius followed by stability assessment of the DRUJ. In rare instances, the reduction of the DRUJ is blocked by interposed structures requiring open reduction of this joint. The purpose of this study is to review all cases of irreducible Galeazzi fracture-dislocations reported in the literature to offer guidelines in the diagnosis and management of this rare injury. METHODS: A search of the MEDLINE database, OVID database, and PubMed database was employed using the terms "Galeazzi" and "fracture." Of the 124 articles the search produced, a total of 12 articles and 17 cases of irreducible Galeazzi fracture-dislocations were found. RESULTS: The age range was 16 to 64 years (mean = 25 years). A high-energy mechanism of injury was the root cause in all cases. More than half of the irreducible DRUJ dislocations were not identified intraoperatively. In a dorsally dislocated DRUJ, a block to reduction in most cases (92.3%) was secondary to entrapment of one or more extensor tendons including the extensor carpi ulnaris, extensor digiti minimi, and extensor digitorum communis, with the remaining cases blocked by fracture fragments. Irreducible volar dislocations due to entrapment of the ulnar head occurred in 17.6% of cases with no tendon entrapment noted. CONCLUSIONS: In the presence of a Galeazzi fracture, a reduced/stable DRUJ needs to be critically assessed as more than half of irreducible DRUJs in a Galeazzi fracture-dislocation were missed either pre- or intraoperatively.
