Barton's Fracture

General Considerations

  • Intra-articular fracture of the distal radius with subluxation/dislocation of the wrist
    • The lunate maintains its relationship with the fracture fragment
  • May involve the volar aspect of the radius (sometimes called “reverse Barton fracture”) or the dorsal aspect
  • Volar type is more common
  • Most common fracture-dislocation of the wrist
