Frykman classification of distal radial fractures

The Frykman classification of distal radial fractures is based on the AP appearance and encompasses the eponymous entities of Colles fracture, Smith fracture, Barton fracture, chauffeur fracture. It assesses the pattern of fractures, involvement of the radioulnar joint and presence of a distal ulnar fracture

Classification

Although it appears complicated, it is actually only a four-type classification (odd numbered types) with each type having a subtype which includes ulnar styloid fracture (these are the even numbered types):

  • type I: transverse metaphyseal fracture
  • type II: type I + ulnar styloid fracture
  • type III: fracture involves the radiocarpal joint
  • type IV: type III + ulnar styloid fracture
  • type V: transverse fracture involves distal radioulnar joint
  • type VI: type V + ulnar styloid fracture
  • type VII: comminuted fracture with the involvement of both the radiocarpal and radioulnar joints
  • type VIII: type VII + ulnar styloid fracture
