Older's classification explained

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]
