Objective To analyze 3 different methods for treatment of Tossy Ⅲ acromioclavicular dislocation. Methods Sixty-two patients with Tossy Ⅲ acromioclavieular dislocation who had been treated by 3 different treatment methods in our department were analyzed. Of them, 18 cases were treated with Kirschner wire and tension wire fixation plus repair of coracoacromial and acromioelavicular ligaments(Group A), 21 with clavicle claw steel plate fixation plus repair of acromioelavicular ligament (Group B ), and 23 with intersecting Kirschner wire plus repair and strengthening of acromioclavieular ligament(Group C). Results After follow-ups for 9 to 24 months (with an average of 15. 6), therapeutic effect(by Karlsson system), operation duration, intraoperative blood loss and cost were evaluated for all the pa-tients. The differences in the therapeutic effect between all groups were not significant ( P ＞ 0.05 ). Group C needed less operation time and had less bleeding than groupA ( P ＜ 0. 05), and group C needed less oper-ation time and cost and had less bleeding than group B ( P ＜ 0. 05). Conclusion Intersecting Kirsehner wire plus repair and strengthening of aeromioclavieular ligament is an efficient, convenient and less costly method for treatment of TossyⅢ aeromioclavicular dislocation.
