Abstract：Objective:To compare the effects of different surgical methods for the treatment of Rockwood type Ⅲacromioclavicular joint dislocation. Methods:Retrospective study was performed in a total of 73 patients with Rockwood type Ⅲ acromioclavicular joint dislocation who were treated with different surgical methods from De-cember 2005 to December 2012 in our Department. Fixation with clavicular hook plate in group A (n=23),repair of coracoclavicular ligament using anchor screw in group B (n=18),and fixation of clavicular hook plate combined with repair of coracoclavicular ligament using anchor screw in group C (n=32).All the patients were admitted to the hospital within 1 week after the inj ury,and received operation within 2-1 2 days after the inj ury,and they were followed up for 12-24 months (average 18 months).The effects were evaluated according to Karlsson standard,and complications were recorded. Results:The excellent rate of shoulder after the operation was 6 9.6%in group A,66.7% in group B,and 93.8% in group C. The rate of excellent result in group C was significantly higher than that in group A and group B (P<0.05).There was no significant difference in the excellent rate be-tween group A and group B(P>0.05).The incidence of postoperative complications was 34.8% in group A, 33.3% in group B,and 6.3% in group C. The incidence of postoperative complications in group C was significant-ly lower than that in group A and group B (P<0.05),but there was no significant difference in incidence of com-plications between group A and group B (P>0.05).Conclusions:For patients with Rockwood type Ⅲ acromio-clavicular joint dislocation,the operative function of shoulder can be significantly improved by fixation of clavicular hook plate combined with repair of coracoclavicular ligament using anchor screw with a few complications. Thus, it is an ideal treatment for Rockwood type Ⅲ acromioclavicular joint dislocation.
