Subtle pediatric wrist fractures often appear on radiographs only as a focal cortical interruption or a fine linear lucency, and the epiphyses, growth plates and overlapping bones make these signs hard to separate. MV-CortexGuard compares cortical continuity across frontal and lateral views in a shared anatomical coordinate frame and refers high-risk examinations for expert review. On the internal GRAZPEDWRI-DX test set it reached 52.7% average precision on the size-defined small-fracture subset, 6.6 points above YOLOv10m, and 63.4% AP@50–95 overall.
