The Use of Hook Plate and Direct Coracoclavicular Ligament Repair in Acromioclavicular Joint Dislocation: Short-Term Result

Background: Acromioclavicular (AC) joint separation/dislocation represents widely recognized as shoulder injuries seen in general orthopedic. The recent biomechanical study of the AC joint made a lot of changes in the Treatment modalities of the joint. Objective: our aim is to report the clinical outcome of management of acute acromioclavicular (AC) joint dislocation type III and V by clavicular hook plate with direct coracoclavicular ligament repair. Patients and Method: A prospective study including thirty Four patients with AC joint dislocation type III and V Rockwood classification was conducted from June 2014 to October 2018 in our University Hospitals. Patients were treated by open reduction of the dislocated AC joint and internal fixation by clavicular hook plate together with direct repair of the coracoclavicular (CC) ligament. Three patients lost during follow up and operation one patient died during follow up from cardiac problem before the surgery. The patients were evaluated by plain radiography for AC joint stability and functionally by Constant-Murley Score.
