    The study analyzed safe anatomical pathways for Schanz screw insertion in adolescents with unstable pelvic fractures.

  • 2

    Pelvic CT imaging of 34 adolescents was reconstructed into 3D models to evaluate screw trajectories and entry points.

  • 3

    The iliac wing corridor showed a shape transition from rectangular to funnel-like, with specific entry angles required.

  • 4

    The supra-acetabular corridor had an S-shaped configuration, with varying trajectory lengths based on anatomical alignment.

  • 5

    Adherence to defined entry points and angles is crucial for minimizing risks and enhancing surgical fixation stability.
