[Objective] To compare the efficacy of double-bundle Endobutton plate with loop and clavicle hook plate in the treatment of acute acromioclavicular joint dislocation. [Methods] From January 2019 to June 2021, 44 patients with acute acromioclavicular joint dislocation who were treated in our hospital were retrospectively analyzed. Among them, 21 patients were fixed with double-bundle Endobutton with loop plate (loop plate group), and 23 patients were treated with hook plate (hook plate group), and the perioperative period, follow-up and imaging data were analyzed and compared between the two groups. [Results] There was no significant difference in operation time, intraoperative blood loss and active activity time between the two groups (P > 0.05); In terms of incision length and hospital stay, the loop plate group was better than the hook plate group, and the difference was statistically significant (P < 0.05). The two groups achieved satisfactory results in pain relief and shoulder function recovery, but with the passage of follow-up time, VAS score, constant Murley score, ROM of forward flexion and upward lift, and ROM of abduction and upward lift were better in the loop plate group than in the hook plate group at 3 months after operation and the last follow-up (P < 0.05). In terms of imaging, the distance between coracoclavicle and acromioclavicular was significantly reduced in the two groups at 3 months after operation and the last follow-up (P < 0.05), but there was no significant difference between the two groups at the same time point (P > 0.05). [Conclusion] Double-bundle Endobutton with loop plate for the treatment of acromioclavicular joint dislocation, compared with hook plate fixation, has the advantages of smaller surgical incision, better shoulder joint function, and less complication rate, and does not require secondary removal. Double-bundle Endobutton with loop plate fixation is a good choice for the treatment of acute acromioclavicular dislocation.
