This study presents a comparative finite element analysis (FEA) of two common plates—Dynamic Compression Plate (DCP) and Locking Compression Plate (LCP)—made from stainless steel and biodegradable magnesium alloy. To improve realism, a patient-specific femur model was used instead of a simplified geometry. A fractured femur with a small gap was modeled, and the plate–bone system was analyzed under static loading. Loads from 140 N to 700 N were applied to represent increasing weight-bearing during healing for a 70 kg person. In this study, healing stages were represented only through increasing load; changes in bone structure or material properties during healing were not modeled. For simplicity, screw geometry was not included, and bonded connections were used. The results show that stainless steel plates remain within safe stress and deformation limits (<160 MPa, <1.6 mm) even at higher loads, making them suitable for full weight-bearing. In contrast, magnesium plates show higher stress and deformation, exceeding their strength at higher loads. This suggests a risk of failure in adults but potential use in low-load cases, such as early healing or pediatric patients. Although the results follow expected material behavior, this study provides a clear comparison using realistic geometry and clinically relevant loading. Future work should include more detailed modeling and experimental validation.
