J024054 上腕骨遠位端骨折に使用する内固定材料の力学的特性評価([J024-05]骨の臨床評価・解析)

Osteosynthesis by the use of "Mayo Clinic Congruent Elbow Plate System" in combination with "Locking Screws (LS)" or "Non-locking Screws (NLS)" was applied to the distally fractured model humeri made of polyurethane. Quasi-static compression tests on the model humeri were then performed in order to clarify their mechanical performance with respect to initial fixation. No significant difference in stiffness was found between the model humeri with NLS and that with LS. All model humeri were able to support the compressive load of 1600N at minimum independently of the type of screws, and therefore it can be concluded that the plates and the screws tested in this study provide the excellent initial fixation for distal humerus fracture.
