Delbet–Colonna Classification — Paediatric Femoral Neck Fractures

Type I: Transepiphyseal (with/without dislocation) — highest AVN risk. Type II: Transcervical (through the neck). Type III: Cervicotrochanteric (basicervical). Type IV: Intertrochanteric. AVN risk decreases from I → IV; urgent reduction and stable fixation reduce complications.
