Case #7


Findings

  • Acute distal radial diaphyseal fracture with approximately one shaft-width radial displacement, apex volar angulation, and 1.5 cm of override
  • Dislocation of the distal radioulnar joint with volar displacement of the ulna, which protrudes through the skin


Diagnosis

  • Galeazzi fracture/dislocation

Sample Report

Acute open Galeazzi fracture/dislocation with a distal radial diaphyseal fracture and dislocation of the distal radioulnar joint with volar displacement of the ulna, which protrudes through the skin. The radial fracture demonstrates approximately one shaft-width radial displacement, apex volar angulation, and 1.5 cm of override.

Radiocarpal joint alignment is maintained.


Discussion

  • Think about the radius and ulna as a ring structure so that if you see one radial/ulnar fracture, look for another fracture or dislocation
  • Monteggia, Galeazzi, and Essex-Lopresti fracture/dislocations all involve paired fractures and dislocations in this ring
    • Monteggia (MUGR): ulnar fracture with proximal radial dislocation
    • Galeazzi (MUGR): radial fracture with distal ulnar dislocation
    • Essex-Lopresti: radial head fracture with disruption of the distal radioulnar joint
