Three-Dimensional Computed Tomography-Based Mapping of the Intraosseous Safe Zone for Acetabular Cup Screw Fixation: A Retrospective, Single-Center Cohort Study

Background

Conventional safe zones are defined by the proximity of acetabular cup screws to intrapelvic vessels; however, this relationship varies among individuals. This study aimed to define the intraosseous safe zone in which the screws remain entirely within bone without penetrating the medial wall.
