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][5]
Frykman Classification
- Frykman classified distal radius fracture based on Location
| 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
- Melone classified distal radius fracture based on Location
| Melone Classification | ||
|---|---|---|
| I | Undisplaced, no or minimal comminution | |
| II | Die punch fracture with moderate to severe displacement | |
| A | Reducible | |
| B | Irreducible | |
| III | Spike fragment present | |
| IV | Wide separation of intra-articular fragments | |
| V | Explosion fracture with severe comminution, transverse split and rotational displacement | |
Fernández Classification
- Fernández classified distal radius fracture based on trauma mechanism
| Fernández Classification | |
|---|---|
| Type 1 | Bending fracture of metaphysis |
| Type 2 | Shearing fracture of joint surface |
| Type 3 | Compression fracture of joint surface |
| Type 4 | Avulsion fractures or radiocarpal fracture-dislocation |
| Type 5 | Combined fractures associated with high high-velocity injuries |
Universal Classification
Type 1 Extra-articular fracture, without deviation Type 2 Extra-articular fracture, with deviation 2A Reducible and stable 2B Reducible and unstable 2C Irreducible Type 3 Intra-articular fracture, without deviation Type 4 Intra-articular fracture, with deviation 4A Reducible and stable 4B Reducible and unstable 4C Irreducible
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
