Case 153 Asset 1 Acromioclavicular (AC) Joint Injuries

Video Transcription

Video Summary

This video reviews two acromioclavicular (AC) joint injuries and the Rockwood classification. A 17-year-old football player had a type II AC injury with widening of the joint and a small coracoid avulsion fracture. A 32-year-old scooter rider initially appeared to have type III injury, but an axillary view showed posterior clavicle displacement, upgrading it to type IV. The video explains Rockwood types I–VI, emphasizes that plain radiographs are usually sufficient, and recommends contralateral comparison and weight-bearing AP views; axillary views help detect posterior displacement.
