The AO classification of clavicular fractures along with the Neer classification system is one of the more frequently used classification systems when assessing distal clavicular fractures.
Classification
The classification system, broken into three categories focuses on the displacement and pattern of the fracture and the integrity of the coracoclavicular ligaments.
Type A
A1 when the fracture is extra-articular. A2 when the fracture is intra-articular
non-operative treatment
fracture is nondisplaced
the coracoclavicular ligament is intact
Type B
B1 when the fracture is extra-articular. B2 when the fracture is comminuted
non-operative or operative treatment can be recommended
fracture is displaced
the coracoclavicular ligament is intact
Type C
C1 when the fracture is extra-articular. C2 when the fracture is intra-articular
operative treatment is recommended
fracture is displaced
coracoclavicular ligament is torn
