Galeazzi fracture involves distal radius fracture with dislocation of which joint?

• A. Proximal radius fracture with elbow dislocation
• B. Distal ulna fracture with DRUJ dislocation
• C. Humeral shaft fracture with shoulder dislocation
• D. Distal radius fracture with distal radioulnar joint dislocation

Answer: (D)

A Galeazzi fracture is a fracture of the distal radius with dislocation of the distal radioulnar joint. This pattern occurs because the force causes a break near the wrist on the radius while the interosseous membrane and the ligaments of the distal radioulnar joint fail, allowing the DRUJ to become unstable or dislocated. That’s why the description of a distal radius fracture with dislocation of the distal radioulnar joint is the best match. The other descriptions describe different injuries: a proximal radius fracture with elbow dislocation is a Monteggia fracture; a distal ulna fracture with DRUJ dislocation involves the ulna more than the radius; and a humeral shaft fracture with shoulder dislocation is a separate injury of the upper arm and shoulder.
