Suture Augmentation of Acromioclavicular and Coracoclavicular Ligament Reconstruction for Acute Acromioclavicular Dislocation

PurposeThe objective of this report was to introduce a new suture augmentation of coracoclavicular and acromioclavicular ligament reconstruction for acute Rockwood grade III to V acromioclavicular dislocations.MethodsFrom January 2015 to January 2019, 43 patients with Rockwood III to VI acute acromioclavicular dislocations were retrospective reviewed. The outcome evaluations included coracoclavicular space, loss of reduction, and acromioclavicular space. The Disabilities of the Arm, Shoulder, and Hand questionnaire was used to assess the limb function. Clinical evaluation of patients was performed using the University of California-Los Angeles scoring systems. For comparison, another series of 28 patients treated with double Endobutton technique from January 2011 to December 2014 was reviewed. A P<0.05 was considered statistical significance.ResultsThe mean follow-up period of the two series were 39.69±7.42 months (range, 24–54 months) and37.86±8.23 months (range, 26–48 months) (P>0.05), respectively. There were significant differences regarding coracoclavicular space (11.62±2.54 mm vs 16.78±5.53 mm; P<0.05), coracoclavicular reduction loss (5.56±4.73 mm vs 26.25±4.42 mm; P<0.05), and acromioclavicular space (6.89±1.87 mm vs 7.95±2.37 mm; P<0.05). There were significant differences regarding the Disabilities of the Arm, Shoulder, and Hand questionnaire (3.3±2.8 vs 5.32±4.37; P<0.05) and University of California-Los Angeles Shoulder rating scale (31.19±2.48 vs 29.24±2.48; P<0.05). The excellent to good percentages were 100 % (n=32) and 85% (n=23), respectively. ConclusionsIn conclusion, the suture augmentation of acromioclavicular and coracoclavicular ligament reconstruction is reliable technique for acute acromioclavicular dislocation with minimal complications.Type of study/level of evidenceTherapeutic IIa.
