Clinical Study on Minimally Invasive Sling Technique Fixation for the Treatment of Acromioclavicular Joint Dislocation with Double Endobutton by Bare-handed
Abstract
Objective: To evaluate the clinical efficacy of minimally invasive, fluoroscopy-free, arthroscopy-free, coracoid tunnel-free double Endobutton plate sling technique for the treatment of acromioclavicular joint dislocation. Methods: A total of 60 patients with acromioclavicular joint dislocation admitted to our hospital between January 2021 and December 2023 were divided into two groups according to the treatment method. The control group underwent open reduction and internal fixation with a clavicular hook plate, while the study group received minimally invasive, fluoroscopy-free, coracoid tunnel-free double Endobutton plate sling fixation. The therapeutic outcomes were compared between the two groups. Results: All surgical outcome measures in the study group were superior to those in the control group (p < 0.05). The improvement in Constant scores and the reduction in visual analog scale (VAS) pain scores was significantly greater in the study group compared to the control group (p < 0.05). Conclusion: The minimally invasive, fluoroscopy-free, arthroscopy-free, coracoid tunnel-free double Endobutton plate sling technique for the treatment of acromioclavicular joint dislocation offers significant advantages, including minimal invasiveness, reduced trauma, reliable fixation, fewer complications, accelerated recovery, and improved joint function.
