Background

  • Seen w/ intra-articular or distal radial shaft fractures or both bone fracture

Imaging

  • PA
    • Narrowing and overlap of distal radioulnar joint
  • Lateral
    • Volar or dorsal displacement of ulna (which is usually centered/overlapping the radius)
    • Requires a true lateral to avoid a false positive result

Differential Diagnosis

Distal radius fractures

Distal radius fracture eponyms

Eponyms Description
Barton's Fracture-dislocation of radiocarpal joint (with intra-articular fracture involving the volar or dorsal lip)
Chauffer's Fracture of radial styloid
Colles' Dorsally displaced, extra-articular fracture
Die-punch Depressed fracture of the lunate fossa (articular surface)
Smith's Volar displaced, extra-articular fracture

Management

  • Dorsal dislocation
    • Immobilize wrist in supination
  • Volar dislocation
    • Immobilize wrist in pronation
