Study Notes
Salter-Harris Classification
- Proposed by Salter and Harris in 1963
- Remains the most widely used system for describing physeal fractures as of January 2023
Classification Mnemonic
- SALTR mnemonic helps to remember the Salter-Harris types
Salter-Harris Types
Type I
- 5-7% of fractures
- Fracture plane passes all the way through the growth plate, not involving bone
- Cannot occur if the growth plate is fused
- Good prognosis
Type II
- ~75% of fractures (most common)
- Fracture passes across most of the growth plate and up through the metaphysis
- Good prognosis
Type III
- 7-10% of fractures
- Fracture plane passes some distance along with the growth plate and down through the epiphysis
- Poorer prognosis due to interruption of the proliferative and reserve zones
Type IV
- 10% of fractures
- Fracture plane passes directly through the metaphysis, growth plate, and down through the epiphysis
- Poor prognosis due to interruption of the proliferative and reserve zones
Type V
- Uncommon
- Fracture plane passes through the growth plate, resulting in a "ruined" or "rammed" appearance
- Poor prognosis
