Milch Type I: Fracture line lateral to trochlear groove (through capitellum–trochlear junction) — more stable. Milch Type II: Fracture line extends into trochlea — less stable (risk of displacement). Jakob/Weiss Displacement Staging: I (<2 mm, intact cartilage), II (≥2 mm with intact hinge), III (≥2 mm with rotation/complete displacement). Treatment: Stage I cast; Stage II–III typically ORIF/CRPP to prevent nonunion and lateral overgrowth.
