A 55-year-old male patient sustained a dislocation of the acromioclavicular (AC) joint in combination with a distal clavicle fracture. ⋯ A combined injury of a complete ac joint dislocation and a distal clavicle fracture is rare and is not included in currently available classification systems; therefore, in this article a classification and assessment of the stability of this injury as well as appropriate treatment options are discussed.
