Salter Harris: Type IV

---

- Discussion:
     - may occur at any age
     - rare in the hand
     - type IV frx potentially interfere with normal growth;
     - frx line crosses physis, separating a portion of metaphysis-physis-epiphysis from the remaining metaphysis-physis-ephiphysis;
     - if frx is displaced, ORIF is indicated;
     - even w/ perfect reduction, growth is affected & prognosis is guarded
