Intervention

Device:
• Anser Clavicle Pin
The Anser Clavicle Pin is an intramedullary device that has been studied in 20 patients in an EU-based prospective case series.28 A 100% union rate was found. The Constant-Murley score at 1-year was 96.7 (SD 5). The Disabilities of 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. VAS satisfaction was 8.9 (SD 1) at the 1-year follow up.
