Older's classification

Older's classification is a system of categorizing Colles' fractures, proposed in 1965.¹ In the Older's classification system there are four types of fractures.²

Classification

Type 1: Dorsal angulation up to five degrees, radial length distal to ulna at least 7 mm.¹
Type 2: Dorsal angulation, radial length 1 to 7 mm, no comminution.¹
Type 3: Dorsal radius comminuted, radial length less than 4 mm, distal fragment slightly comminuted.¹
Type 4: Marked comminution, radial length usually negative.¹
