Objectives: Recent studies report nonunion rates of up to fifteen percent for nonoperative treatment of displaced, comminuted, or shortened midshaft clavicle fractures. Additionally, authors suggest operative treatment of these comminuted displaced midshaft clavicle fractures leads to a more satisfactory clinical outcome. Biomechanically, clavicle fracture plate fixation has been analyzed for locking versus non-locking screw use, but little evidence on hybrid screw use exists. We hypothesized that fixation of a comminuted midshaft clavicle fracture model with a pre-contoured hybrid screw-plate construct would increase stiffness and load-to-failure compared to a non-locking screw construct. Methods: Fourteen matched pairs of fresh frozen cadaveric clavicles …
