Arthrography in dislocation of the acromioclavicular joint

Arthrography was performed in 10 patients with dislocation of the acromioclavicular joint. The examination was unsuccessful in one case. In the remaining 9 patients, leakage of the contrast medium was observed around the joint and in the direction of the coracoid process. The arthrographic abnormalities were compared with the findings at operation. The distribution of the medium that had leaked out provided information on the severity of the injury to the ligaments.
