    Pauwels Type III femoral neck fractures pose high risks of complications, including fixation failure and avascular necrosis.

  • 2

    Biomechanical stability in these fractures is influenced by screw configuration, with inverted triangle and L-shaped arrangements being compared.

  • 3

    The medial buttress plate (MBP) enhances screw fixation by neutralizing shearing forces, while the anteromedial support plate (ASP) offers a safer surgical approach.

  • 4

    This study utilized composite femurs to standardize conditions and compare five fixation constructs for biomechanical performance.

  • 5

    The hypothesis suggests that the ASP may provide comparable stability to the MBP when combined with appropriate screw configurations.
