Acromial fracture associated with ipsilateral acromioclavicular (AC) joint dislocation is rare in adults and has not been reported previously. A 42-year-old woman presented to the emergency department and was diagnosed with a type III acromial fracture on initial radiographic assessment. Open reduction internal fixation was selected and performed immediately based on the diagnosis. However, the postoperative X-rays revealed AC joint dislocation (type III) that was not apparent on the initial assessment. The pattern of injury involved disruption of the AC and coracoclavicular ligament complex. The decision to re-operate was made based on these findings, and the dislocation was reduced and fixed. Acromial base fractures may make it difficult to accurately diagnose concomitant dislocations. The findings underline the importance of careful evaluation of X-rays and suggest the use of additional imaging in cases of doubt. We also review the literature and important aspects in the management of such cases.
