Acromioclavicular (AC) joint dislocation is a common injury of the shoulder. In contrast to traumatic causes, nontraumatic dislocations are very rare. We report one case of a young active male who presented with voluntary recurrent dislocation of the AC joint. Clinical examination showed dislocation in the anteroposterior direction of the AC joint. The patient underwent conservative management. Conservative treatment along with lifestyle modifications is sufficient for pain control and associated symptoms. Regular follow-up is very important.
