Abstract
In 1967 Allman proposed a classification system referring to three types of acromioclavicular joint dislocations (ACJ) [1]. The system was modified by Rockwood who added another three types (types 4, 5 and 6) to complete the classification [2]. The injuries are classified on the basis of findings from physical examination and radiological imaging (anteroposterior and axillary shoulder views). The degree of damage to the acromioclavicular and coracoclavicular ligaments, as well as to the deltoid and trapezius S shaped attachments, is also considered, (Fig. 1.1).
