Two cases of complete dislocation of the acromioclavicular joint associated with coracoid fracture, which has been reported previosly to be a rare condition, were treated surgically. In the radiological diagnosis, a plain anterior-posterior oblique roentogenogram with a 30 degree caudad tilting angle and three-dimensional computed tomogram were very useful as compared with the conventional view. Sound fixation of the coracoid process was important for achievement of stability of the acromioclavicular lesions.
