Abstract

Background: Multiple surgical techniques have been described for the treatment of unstable acromioclavicular (AC) dislocation injuries. However, consensus on the most adequate procedure is yet to be established. This study aimed to evaluate the clinical and radiological results of a single cohort of patients treated with an arthroscopically assisted endobutton coracoclavicular (CC) reconstruction and AC suture anchor-button internal brace technique.
Methods: A total of 15 patients were evaluated with a minimum follow-up of two years. The clinical evaluation comprised a complete physical examination of both shoulders and an assessment of shoulder function scores. Bilateral anteroposterior stress views were obtained before and at the time of the last follow-up for radiological evaluation. Additionally, the CC distance and AC distance were measured on both sides.
Results: On average, 94.8 points and 32.6 points were noted in the constant score and the University of California-Los Angeles shoulder scale, respectively. Regarding the constant score, the contralateral side averaged 96 points. This difference was not statistically significant. The average CC difference was reduced from 13 mm preoperatively to 2 mm postoperatively. The average AC difference was reduced from 16 mm preoperatively to 3.5 mm postoperatively. The mean time to return to sport was 3.6 months, and the mean time to return to professional competition was four months.
Conclusion: An arthroscopically assisted endobutton CC reconstruction and AC suture anchor-button internal brace technique with excellent functional results and good radiological outcomes having a low complication rate has been reported by this study.
