Neer classification (parts displaced >1 cm or >45°): guides management. Non‑operative for minimally displaced; ORIF (locking plate) for displaced 2–3 part; hemiarthroplasty/RSA for unreconstructable 3–4 part or head‑split in elderly. Assess vascularity: medial hinge, calcar length; tuberosity integrity crucial for outcomes. Complications: AVN, stiffness, tuberosity nonunion/malposition, screw perforation.
