Salter-Harris Classification
February 15th, 2021
Overview
The Salter-Harris classification is a system for classifying fractures involving the growth plate. Such fractures have the potential of interrupting the proliferative zone, halting bone growth; higher grade fractures are at higher risk.
Classification
- IStraight through - fracture directly across the growth plate, not involving surrounding boneGood prognosis
- IIAbove - fracture across the growth plate and up through the metaphysis (most common)Good prognosis
- IILower - fracture across the growth plate and down through the epiphysisPoor prognosis - interruption of proliferative zone
- IVTransverse - fracture directly through the metaphysis, growth plate and epiphysisPoor prognosis - interruption of proliferative zone
- VRuined / rammed - direct compression of the growth plateWorst prognosis
