Comparison of Single Tunnel Versus Double Tunnel Techniques for Coracoclavicular Stabilization in Acromioclavicular Joint Injuries

There are now over 150 techniques of operative treatment for Acromioclavicular joint injury. Despite no techniques used nowadays is recommended as gold standard treatment, most surgeons prefer Coracoclavicular-stabilization technique. Coracoclavicular-stabilization, providing favorable outcomes in many studies, regularly conducted with two surgical techniques which are single tunnel technique and double technique. Although, both techniques result in good biomechanic, patients underwent double tunnel technique report better clinical outcome. However, double tunnel technique compared to single tunnel technique is more challenging in surgical steps and risk intraoperative complications. This trial aims to compare both clinical and radiological outcomes of the two mentioned Coracoclavicular-stabilization techniques, in order to provide data to support treatment decision in patient with acute Acromioclavicular joint injury.
