Overview
There are multiple classifications available for distal radius fractures. The most common classification systems for distal radius fractures include Frykman, Melone, Fernández, Universal, and AO classification. (Marsh et al. 2007).
Classification
There are multiple classifications available for distal radius fractures. The most common classification systems for distal radius fractures include Frykman (1967), Melone (1984), Fernández (2001), Universal (Cooney 1993), and AO classification (Marsh et al. 2007).[1][2][3][4]
Frykman Classification
| Frykman Classification | |
|---|---|
| I | Extra-articular |
| II | Extra-articular with ulnar fracture |
| III | Intra-articular into radiocarpal joint |
| IV | Intra-articular into radiocarpal joint with ulnar fracture |
| V | Intra-articular into radioulnar joint |
| VI | Intra-articular into radioulnar joint with ulnar fracture |
| VII | Intra-articular into radiocarpal + radioulnar joints |
| VIII | Intra-articular into radiocarpal + radioulnar joints with ulnar fracture |
Melone classification
(I: undisplaced, no or minimal comminution; II: ’die punch’ fracture with moderate to severe displacement (IIa: reducible; IIb: irreducible); III spike fragment present; IV: wide separation of intra-articular fragments; V explosion fracture with severe comminution, transverse split and rotational displacement)
OTA System
The Trauma Association classification is widely accepted and under constant review. (More details available here.)
- (21-A) Extra-articular
- (21-A2) Radius only
- (21-A3) Radius and ulna
- (21-B) Articular fracture involving articular surface of only one of the two bones
- (21-B2) Radius fractured, ulna intact
- (21-B3) Articular of one bone, extra-articular of other
- ((21-C) Articular fracture involving articular surface of two bones
- (21-C2) Simple of one, multifragmentary of other
- (21-C3) Multifragmentary of both
