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]
