Comparison results of acromioclavicular dislocation treatment by screw with and without coracoclavicular ligamentous repair

Abstract

Background: Acromioclavicular dislocation is one of the most common shoulder injuries among athletes, and appropriate treatment of acromioclavicular joint dislocation is controversial. Acromioclavicular ligament (AC) and Coracoclavicular(CC) are the most important joint stabilizers. In joint dislocation the ligaments are torn, therefore the repair of these ligaments play an important role in increasing the joint stabilization after surgical treatment. The purpose of this study was to compare treatment results of Acromioclavicular dislocation with Coracoclavicular(CC) ligament repair and without it. Methods: In a descriptive analytical study, 40 patients with acute acromioclavicular dislocation required operative treatment were studied. In the target group in addition to an open reduction and fixation with screws, Coracoclavicular(CC) ligament repair with non-absorbable suture was done. Two groups were compared in terms of clinical outcome and functional ability and complications. Results: In this study, 40 patients were studied, including 39 males (97.1%) and 1 female (2.6%) were studied. The mean age was 31.6 ± 8.1 years. Comparisons of patient’s performance according to Constant Score showed a significant difference between two groups. So that has been in the ligament repaired was 8.7 ± 1.7 and in other group was 10.1 ± 2.1. Also according to the Constant on ligament repair was higher points score 90% excellent and 10% good, the other group rated was 70% excellent and 30% good. Coracoclavicular (CC) distance in patients undergoing CC ligament repair was significantly reduced and was equally to the healthy side While in the cases without ligament repair was not diminished coracoclavicular(CC) distance. No complications were observed in the groups. Conclusion: Coracoclavicular(CC) ligament repair lead to better functional ability in patients with acute acromioclavicular dislocation and not associated with any symptoms.
