Fracture of radius - Frykman classification of distal radial fractures
Frykman classification of distal radial fractures describes eight types. It is based on the involvement of the radiocarpal and the distal radioulnar joints. Even types are based on odd types with additional fracture of the ulnar styloid process. However, this traditional classification has little impact on treatment decision or outcome, because it does not consider the extent or direction of displacement or shortening.
| Type | Description |
|---|---|
| Type I | transverse metaphyseal fracture, this type include Colles' and Smith's fracture |
| Type II | type I + fracture of the ulnar styloid process |
| Type III | fracture involving the radiocarpal joint, this type includes Barton and reverse Barton fracture |
| Type IV | type III + fracture of the ulnar styloid process |
| Type V | transverse fracture involving the distal radioulnar joint |
| Type VI | type V + fracture of the ulnar styloid process |
| Type VII | comminuted fracture involving both the radiocarpal and the distal radioulnar joint |
| Type VIII | type V + fracture of the ulnar styloid process |
