A Novel Treatment for Proximal Clavicle Fracture Combined With Sternoclavicular Dislocation

Purpose: The aim of this study was to evaluate the clinical results of sternoclavicular hook plate and anterior sternoclavicular ligament repair in proximal clavicle fractures. Methods: : Between October 2016 and December 2020, a total 16 patients (9 male and 7 female patient, with a mean age of (42.25±10.24) years (range,25-56 years) with unstable proximal clavicle fractures (Throckmorton, type D) were treated with sternoclavicular hook plate, and anterior sternoclavicular ligament repair. Affected side, cause of the injuries, dislocation type, associated injuries, interval between injury and surgery, and duration of follow-up were recorded. The outcomes were evaluated with radiographic assessment, American Shoulder and Elbow Surgeons’ Form(ASES). All the patients were evaluated on postoperative 3rd, 6th, and 12th months. Results: : According to the ASES scoring system, the average score was 49.50±3.76 (preoperative score),86.94±5.09 (3 months follow-up), 88.32±3.07 (6 months follow-up) and91.00±2.92 (12 months follow-up).Statistics differences was showed between preoperative and 3,6,12 months follow-up score of ASES SCJ score (p < 0.05).The postoperative physical function was better than the preoperative function. Conclusion: Fixation using a sternoclavicular hook plate combined with repair of the ligament and capsule isrelatively easy to do; it provides micromotion, which is beneficial for the movement of the shoulder girdle. Our study indicates that open reduction and sternoclavicular hook plate fixation for the treatment of traumatic sternoclavicul-ar joint dislocations or fracture is a safe, relatively straightforward surgical procedure that can lead to satisfactory outcomes.
