A novel sternoclavicular hook plate for treatment of proximal clavicle fracture with dislocation of sternoclavicular join

Abstract Purpose The aim of this study was to explore the efficacy of sternoclavicular hook plate for treatment of proximal clavicle fracture with dislocation of sternoclavicular joint. Methods Between October 2016 and December 2020, 16 cases (9 male and 7 female patient, with a mean age of (42 ± 10) years) of proximal clavicle fracture with dislocation of sternoclavicular joint were included in the study. Injured side, injury mechanism, time to surgery, Complications 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 ± 4 (preoperative score), 87 ± 5 (3 months follow-up), 88 ± 3 (6 months follow-up) and 91 ± 3 (12 months follow-up). Statistics differences was showed between preoperative and 3,6,12 months follow-up score of ASES score (p < 0.001). The postoperative physical function was better than the preoperative function. Internal fixation failure and fracture non-union complications in two patients. Conclusion Our study indicates that open reduction and sternoclavicular hook plate fixation for the treatment of traumatic sternoclavicular fracture is a safe, relatively straightforward surgical procedure that can lead to satisfactory outcomes.
