by up to 19.1% but redistributed heat more uniformly across the implant, lowering peak temperatures compared to intact screws. In the human voxel model, fractured screws remained below the IEC safety limits under maximum permissible RF exposure with a maximum temperature elevation of 38.9 °C, whereas non-fractured screws exceeded 40 °C. Our results demonstrate that Mg screw degradation generally mitigates MRI heating risks. In conclusion, engineered degradation features may enhance MRI safety, providing design guidance for next-generation biodegradable orthopedic implants.
