title: Anterior dislocation of the acromioclavicular joint.
abstract: A rare type of acromioclavicular dislocation is described. The right acromion of a 25-year-old woman was traumatically luxated in front of the distal clavicle. The luxation was not detected in the primary examination as the prominence of the acromioclavicular joint was missed and the trauma was almost indiscernible in X-rays taken with conventional projections. The diagnosis was finally confirmed with oblique craniocaudal radiographs. The painful dislocation was corrected surgically. Anatomical reduction and ligament reconstruction produced an excellent result.
