Tillaux: Anterolateral epiphyseal avulsion (SH-III) during asymmetric physeal closure — intra-articular; >2 mm step needs fixation. Triplane: Multi-planar SH-IV variant (sagittal epiphysis, axial physis, coronal metaphysis); 2-, 3-, or 4-part patterns. CT delineates fragments to plan screw fixation; restore joint congruity to prevent arthritis.
