Salter–Harris Classification — Physeal (Growth Plate) Injuries

Type I: Through physis only (slip) — good prognosis; often in younger children. Type II: Through physis and metaphysis (Thurston–Holland fragment) — most common; good prognosis. Type III: Through physis and epiphysis into joint — needs anatomic reduction (articular). Type IV: Through metaphysis, physis, and epiphysis — high risk of growth arrest; ORIF often required. Type V: Crush injury to physis — rare, poor prognosis; often diagnosed retrospectively by growth arrest. Extended: Rang VI–IX (periosteal injury, perichondrial ring, etc.) are occasionally referenced for completeness.
