Rockwood classification of acromioclavicular joint injury: annotated radiographs

Case contributed by Dr Jeffrey Hocking

X-ray normal left shoulder - AP, lateral and axial

X-ray bilateral left shoulder type II injury. AC ligament: complete tear. CC ligament: partial rupture. (White dotted line demonstrates normal clavicle location)

X-ray bilateral left shoulder type III injury. AC ligament: complete tear. CC ligament: complete tear. Elevated distal clavicle + widening of CC space (white dotted line demonstrates normal clavicle location)

X-ray lateral/Scapular Y-view right shoulder demonstrating type IV injury. Clavicle can be seen overriding the acromion. This is suggestive of a posterior clavicle dislocation (2)

X-ray bilateral right shoulder type V injury. AC ligament: complete rupture. CC ligament: complete rupture. Superior displacment of clavicle + increase of CC distance by 100-300% (white dotted line demonstrates normal clavicle location)

X-ray right shoulder subcoracoid type VI injury AC ligament: complete rupture CC ligament: complete rupture (white dotted line demonstrates normal clavicle location). Modified with permission (3)
