    The study analyzed CT data from 71 patients with Sanders type II and III intra-articular calcaneal fractures caused by falls from height.

  • 2

    Significant displacement of the posterior facet fragment occurred in all directions, with predominant lateral and inferior translations.

  • 3

    Primary rotational deformities included axial plane internal rotation of 17.62° and sagittal plane anterior tilt of 12.29°.

  • 4

    3D reconstruction technology was employed to enhance the assessment of fracture morphology and support preoperative planning.

  • 5

    The findings provide a quantitative anatomical reference for reduction planning, although further validation is required.
