Abstract

Introduction: The treatment of acute acromioclavicular (AC) dislocation using double-button fixation with FiberTape™ and Dog Bone™ neutralized with an AC hook plate (HP) could provide a stable anatomical reduction, resulting in faster rehabilitation and functional recovery.

Objective: To describe short-term radiological and clinical outcomes (minimum one-year of follow-up) achieved with the use of double-button fixation with FiberTape™ and Dog Bone™ neutralized with an AC HP for the surgical treatment of acute AC dislocation.

Methodology: Retrospective study in which the medical records of patients with acute AC dislocation undergoing open anatomic reduction surgery using the modified double- button fixation technique with FiberTape™ and Dog Bone™ between 2017 and 2019 were reviewed. Radiological stability was assessed through the coracoclavicular (CCD) and AC (ACD) distances in the affected and contralateral shoulder. Pain and function were assessed using the visual analogue scale (VAS) and the QuickDASH score, respectively.

Results: Eleven patients were included. The median follow-up was 20 months. AC dislocations were classified as type IV (n=9) and V (n=2) according to the Rockwood classification. An improvement in the postoperative median CDD (20.5mm vs. 7.1mm; p=0.000) and ACD (15.2mm vs. 5.1mm; p=0.001) of the affected shoulder was observed. Moreover, the median CDD of the operated shoulder was 101.9% of the contralateral shoulder. No patient presented with scapular reluxations or dyskinesia. The median improvement in shoulder function on the QuickDASH score was 19 (p=0.003). Finally, the median VAS score at the last assessment was 1.

Conclusion: The double-button fixation technique provided reliable and stable healing, resulting in early functional recovery with no short-term reluxations.
