Older's classification
Older's classification is a system of categorizing Colles' fractures, proposed in 1965.{{cite journal|last1=Andersen|first1=G. R.|last2=Rasmussen|first2=J.

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