Percutaneous suture-button fixation for acute acromioclavicular joint dislocation: A case series

Background: Various fixation techniques exist for acute acromioclavicular joint (ACJ) dislocations. Percutaneous suture-button systems aim to restore coracoclavicular (CC) stability with minimal hardware morbidity and operative time, particularly in Rockwood types III and V injuries. Methods: A total of 10 patients (age: 22–47 years) with acute ACJ dislocation (Rockwood types III and V) who underwent percutaneous suture-button CC fixation between 2022 and 2025 were included in this case series. Functional outcomes were assessed using the Constant–Murley Score (CMS) and return to activities of daily living (ADL). Radiological assessment included CC distance measurements on serial radiographs obtained preoperatively, immediately postoperatively, and at final follow-up. Complications were also recorded. Results: The mean follow-up was 5.9 months (range: 4–8 months). The mean CMS improved from 33 preoperatively to 91.8 at final follow-up. The mean CC distance decreased from 27 mm preoperatively to 9.9 mm immediately postoperatively and was maintained at 8.8 mm at final follow-up. No complications were observed. All patients returned to ADL at a mean of 6.2 weeks. Conclusion: Percutaneous suture-button fixation provided reliable radiographic reduction and significant functional improvement with low complication rates in acute ACJ dislocations. Larger comparative studies with longer follow-up are needed to further validate these findings.
