Özet
This study explores the relation between corrosion behavior and fatigue performance of Aluminum alloy as a biomaterial for intertrochanteric femoral fracture fixation using Schanz screws. Finite element analysis via ANSYS Workbench software revealed a fatigue life of approximately 6 months for the screws, with a safety factor of 1.66. The dynamic fatigue test results indicated favorable fatigue performance of the aluminum alloy. Despite this, biocompatibility and corrosion concerns remain regarding aluminum alloys. Hence, it is suggested to adopt a biomaterial with superior fatigue performance for Schanz screws to ensure fixator safety during patient mobilization. Additionally, proposing a real-time monitoring Digital Twin Model for aluminum alloy-based Schanz screws is recommended. Equipped with sensors, this model enables continuous data collection on corrosion, stress, and temperature, aiding healthcare professionals in early issue detection and predictive maintenance, thus enhancing long-term reliability and safety of orthopedic implant systems. © The Author(s), 2024.
