Background: We performed modified Neviaser's procedure for acromioclavicular dislocation. We evaluated postoperative radiographs of cases which had modified Neviaser's procedure performed. We performed this method on 23 cases, 18 males and 5 females, from April 2006. The age of the cases ranged between 20 and 73 years old (mean 37.3 years old), and 8 cases were classified in Rockwood type III and 15 cases were Rockwood type V. Methods: We evaluated radiographs to determine whether dislocation appeared again or not after operation. Results: All cases had a complete reduction after operation but 22 cases had a subluxation of acromio-clavicular joint at last examination. Of these 22 cases, 16 cases (5 cases in type III, 11 cases in type V) had a severe subluxation. Almost all cases had a subluxation after we removed Kirshner wire using acromio-clavicular joint fixation. Conclusion: The result suggests that the fixation between clavicle and coracoid process may be effective to keep the reduction of acromio-clavicular joint. The improvement of the surgical technique is necessary.
