ZIMBRON LOPEZ, Daniel et al. Acromioclavicular dislocation treatment. Comparison of three different surgical techniques. Acta méd. Grupo Ángeles [online]. 2018, vol.16, n.1, pp.35-40. ISSN 1870-7203.

The acromioclavicular dislocation is a common injury and represents 12% of all shoulder injuries. There are more than 60 descriptive techniques for coracoclavicular ligament complex reconstruction but a preferred technique has not been established yet. The objective of this study is to compare the postoperative functional status of the patients and the efficacy of the reduction of the three most used techniques for acromioclavicular reconstruction in our Institution (Modified Bosworth technique, acromioclavicular TightRope® system and acromioclavicular hook plate). We have evaluated 52 patients in an age range between 19 and 52 years (mean = 35.87) with the diagnosis of type III acromioclavicular dislocation of the Tossy-Rockwood classification that received treatment with one of the techniques mentioned that received six month follow-up as minimum, and their functional status were evaluated with the DASH score. The statistical analysis was realized with the Kruskal-Wallis test for the comparison of independent means in small samples (p = 0.033) and then make the verification with the Mann Whitney and Bonferron comparison test. According to our results there is a functional positive difference for acromioclavicular TightRope® system (p = 0.013 IC = 95%) versus p = 0.127 of modified Bosworth with acromioclavicular hook plate and p = 0.152 of modified Bosworth with acromioclavicular TightRope® System.
