Presentation
Shoulder trauma following a road traffic accident.
Patient Data











acromioclavicular dislocation with probable tear of the coracoclavicular ligament
bony flecks avulsion from the distal aspect of the clavicle
full-thickness tear of the supraspinatus tendon
mild articular surface tear of the footprint of the infraspinatus tendon
-
mild soft tissue oedema and joint effusion



Dislocation of the right acromioclavicular joint with an elevation of the clavicle above the superior border of the acromion (the coracoclavicular distance is still less than twice normal)





The small bone fragments are best seen on CT.
