AC joint injuries are graded from 1-6 using the Rockwood scale which classifies injuries in relation to the extent of ligament damage and the space between the acromion and clavicle
Grade 4, 5, and 6 separations are severe injuries with high degree of displacement of the clavicle with respect to the acromion and usually require surgery.
Grade 4 involves posterior displacement and grade 5 superior displacement, to a greater degree than grade 3, with an increase in coracoclavicular space by 3-5 times the norm.
