Frykman classification is a system of categorizing Colles' fractures. In the Frykman classification system there are four types of fractures.1

Classification

Though the Frykman classification system has traditionally been used, there is little value in its use because it does not help direct treatment. The classification is as follows:2

Radius Fracture Ulna Fracture
Absent Present
Extra articular I II
Intra-articular involving radiocarpal joint III IV
Intra articular involving distal radio-ulnar joint V VI
Intra articular involving both radiocarpal & distal radioulnar joints VII VIII
