Abstract
Background: Currently, the surgical treatment for acute acromioclavicular injuries with good results is arthroscopic surgery. However, because it is a difficult procedure and requires specific equipment, there are other surgeries that are easier and faster.
Objective: To evaluate the outcomes and associated factors of operative treatment for acromioclavicular joint injury at Mahasarakham Hospital.
Methodology: This retrospective analytic study reviewed data from 63 patients diagnosed with closed acromioclavicular joint injuries between January 1st, 2020, and June 30th, 2024. All patients were followed up until complete joint healing was achieved.
Results: All three treatment methods in the study yielded favorable outcomes. Hook plate fixation significantly improved both the coracoclavicular distance (CCD) (P = 0.036), restoring near-normal anatomical alignment. Endobutton fixation also significantly reduced pre- and post-operative CCD and ACD values. Among all groups, the endobutton method achieved the greatest reduction in pre- to post-operative CCD and ACD by 10.5 ± 4.1 mm (P < 0.001) and 10.2 ± 4.4 mm (P < 0.001). However, there were no statistically significant differences in post-operative ACD among the three groups.
Conclusion: Operative management of acute acromioclavicular joint injury can yield favorable outcomes when treated with hook plate fixation or endobutton fixation. However, careful consideration of the potential complications associated with each technique is recommended.
