Older’s [18] classification of distal radial fractures.

Type I: Non-displaced, length of radial styloid ≥7 mm, dorsal angulation ≤5°.
Type II: Displaced with minimal comminution of dorsal radius, length of radial styloid <7 mm and ≥1 mm, dorsal angulation >5°.
Type III: Displaced with slight dorsal comminution, length of radial styloid ≤4, dorsal angulation >5°.
Type IV: Comminution of distal radius (including the dorsal part), often with intraarticular involvement. Length of radial styloid usually negative, dorsal angulation >5°.
