Drew Medical Center, 12021 South Wilmington Avenue, 90059, Los Angeles, California aut Grade IV acromioclavicular dislocations: Pitfalls in diagnosis in the adolescent [Elektronische Daten] [Janis Owens] A review of the literature shows that posterior dislocation of the distal clavicle or grade IV acromioclavicular dislocation is an uncommon complication of trauma to the shoulder. It is important to make the proper diagnosis, because, in most cases, a surgical reduction is required, in contrast to grade I, II, and III dislocations, which can be adequately treated without surgery in the adult. The diagnosis may not always be evident on physical examination and may be incorrectly diagnosed if only frontal shoulder radiographic examinations are performed. This problem is more complex in the adolescent and child, in whom the criteria used in adults are not applicable because of the nonossified portions of the joints of the shoulder. This case report demonstrates the need to add an axillary view to the traditional shoulder projections to overcome these pitfalls.
