Background: Surgical management of displaced midshaft clavicle fractures in adults leads to better union rates, improved early functional outcomes, and increased patient satisfaction compared with nonoperative treatment. However, both intramedullary fixation and plate osteosynthesis are subject to a specific array of disadvantages and complications. The Anser Clavicle Pin is a novel intramedullary device designed to address these disadvantages and complications. The aim of this study was to evaluate the union rate, functional outcomes, and complications of the Anser Clavicle Pin at 1-year follow-up. Methods: A prospective explorative case series including 20 patients with displaced midshaft clavicle fractures was performed in 2 hospitals. The primary outcomes were union rate, functional outcomes (Constant-Murley score and Disabilities of the Arm, Shoulder and Hand score), and complications. The secondary outcomes were closed reduction rate, operative time, image-intensifier time, hospital stay, incision length, time to radiologic union, postoperative pain reduction, reoperation rate, health-related quality-of-life score, and patient satisfaction. Results: There was a 100% union rate. The Constant-Murley score at 1 year was 96.7 (standard deviation [SD], 5). The Disabilities of the Arm, Shoulder and Hand score was 5.1 (SD, 10). There were no infections, neuropathy of the supraclavicular nerve, or hardware irritation requiring removal of hardware. Three device-related complications (15%) occurred, including plastic deformation, protrusion, and hardware failure. The satisfaction score was 8.9 (SD, 1) on the visual analog scale at the 1-year follow-up. Conclusion: Managing displaced midshaft clavicle fractures with the Anser Clavicle Pin results in a 100% union rate and excellent functional outcomes and patient satisfaction. It has a low non–device-related complication rate, and the device-related complications that occurred in this series may be prevented in the future. |
