Presentation
Motorcycle accident. Wrist deformity upon physical examination.
Patient Data
Distal radial fracture associated with a dislocation of the distal radioulnar joint, which describes a Galeazzi fracture-dislocation.
Case Discussion
Galeazzi fracture-dislocations are described as distal half radial fractures associated with a disruption of the distal radioulnar joint (DRUJ).
Unlike isolated radial fractures, a Galeazzi fracture in an adult demands operative management.
In the present case, the DRUJ is clearly disrupted, but sometimes the injury may be more subtle. Some radiographic findings suggestive of a DRUJ injury are:
ulnar styloid base fracture
widening of the DRUJ
dislocation/subluxation of the radius relative to the ulna on the lateral view
shortening of the radius >5 mm
