Though conventional Ti\u2010alloy used in implant materials provides adequate strength, it induces high strain shielding and also requires secondary removal surgery. In contrast, biodegradable magnesium alloys demonstrate better biocompatibility and are emerging as promising alternatives for implant applications. To evaluate the biomechanical behaviour of femoral neck fractures (Pauwels Types I\u2013III) in a subject\u2010specific femoral model treated with the femoral neck system (FNS) made from Ti\u2010alloy and time\u2010dependent biodegradable Mg alloy. A femoral model was reconstructed from the CT\u2010scan data of a healthy adult male and Pauwels Types I\u2013III fracture patterns were subsequently generated. Finite element simulations were conducted under both normal walking and stair\u2010climbing load conditions. Ti\u2010alloy properties were constant, while Mg\u2010alloy modulus was updated daily over 1\u2009year using an exponential degradation model. Bone remodelling was simulated using a strain energy\u2010based algorithm. Strain shielding at the equilibrium state decreased by as much as 45.55% in the Mg\u2010alloy implant model compared with its immediate PO condition and a similar decrease of around 11.44% was observed in the Ti\u2010alloyed model. The cut\u2010out risk after reaching the equilibrium (AE) condition was reduced by up to 6.74% for the Mg\u2010alloy case compared to the PO scenario. Mg\u2010alloy implants demonstrated greater bone apposition (up to 1.13\u2009g\/cm\n                    <jats:sup>3<\/jats:sup>\n                    ) compared to the Ti\u2010alloyed implant in AE conditions. Micromotion remained below 150\u2009\u03bcm in all models and decreased by approximately 24% after reaching equilibrium. Mg\u2010alloy FNS implants enhance physiological load transfer, reduce shielding and maintain fixation stability during degradation, indicating strong potential as biodegradable alternatives to Ti\u2010alloy implants for femoral neck fracture fixation.\n
