Tillaux: Anterolateral epiphyseal avulsion (SH-III) during asymmetric physeal closure — intra-articular; >2 mm step needs fixation. Triplane: Multi-pl...
Type I: Anterior radial head dislocation with anterior angulated ulnar fracture — most common in children. Type II: Posterior/posterolateral dislocati...
Type I: Nondisplaced — anterior humeral line intersects capitellum; treat in long arm cast. Type II: Displaced with posterior cortex intact (hinge) —...
Milch Type I: Fracture line lateral to trochlear groove (through capitellum–trochlear junction) — more stable. Milch Type II: Fracture line extends in...
O’Brien Angulation: I (60°). Displacement/translation also matters; >3 mm or severe angulation predicts need for reduction/fixation. Metaizeau (elasti...
Type I: Transepiphyseal (with/without dislocation) — highest AVN risk. Type II: Transcervical (through the neck). Type III: Cervicotrochanteric (basic...
Type I: Minimally displaced avulsion. Type II: Hinge of posterior fibers intact (anterior lift) — may reduce closed; fixation if interposed tissue. Ty...
Grade 0: minimal; 1: superficial abrasions/contusions; 2: deep contaminated abrasions, muscle contusion; 3: extensive crush, compartment risk. Higher...
Posterior elbow dislocation + radial head fracture + coronoid tip fracture. Requires concentric reduction, radial head fixation/replacement, coronoid/...
Medial hinge disruption >2 mm, anatomic neck fracture, head-splitting → high AVN risk. Assists decision towards arthroplasty in ischemic patterns.
