Bony consolidation, complication rate, and functional outcomes, including overall health, were assessed.Results: A total of 26 clavicles in 25 patients with a mean age of 50.7 (16– 85) years, 16 male and 9 female, were enrolled in the study. The mean follow-up was 14.9 (6– 31) months. There were 18 cases of displaced clavicle fractures, four refractures, two delayed unions and two non-unions. The majority of the clavicle lesions were located at the middle third (17/26, 65.4%), seven at the lateral third (26.9%) and two at the medial third (7.7%) of the clavicle. A mean Goldberg score of 7 indicated complete bony union and remodeling of the bone graft substitute in all cases. No complications occurred. The mean University of California at Los Angeles Shoulder Score and the mean Quick Disability of the Arm, Shoulder and Hand Score were 34.6± 0.8 (32– 35) points and 0.6± 1.6 (0– 5.4) points, respectively, and revealed excellent functional results. The mean 12-item Short-Form Survey physical component questionnaire was 57.7± 1.7 (54.1– 58.9) points, and no patient experienced any pain at the last follow-up.Conclusion: Our initial experience suggests that ORIF using a plate plus bone defect filling and/or implant augmentation with a gentamicin-eluting bone graft substitute may be useful not only for complication management after clavicle fractures but also in the initial treatment of challenging clavicular fractures.Keywords: clavicle, trauma, non-union, defect augmentation, bone graft substitute
