Salter-Harris Classification

https://radiopaedia.org/articles/salter-harris-classification
Conveniently the Salter-Harris types can be remembered by the mnemonic SALTR.

• type I
  • slipped
  • 5-7%
  • fracture plane passes all the way through the growth plate, not involving bone
  • cannot occur if the growth plate is fused cit
  • good prognosis
• type II
  • above
  • ~75% (by far the most common)
  • fracture passes across most of the growth plate and up through the metaphysis
  • good prognosis
• type III
  • lower
  • 7-10%
  • fracture plane passes some distance along the growth plate and down through the epiphysis
  • poorer prognosis as the proliferative and reserve zones are interrupted
• type IV
  • through or transverse or together
  • intra-articular
  • 10%
  • fracture plane passes directly through the metaphysis, growth plate and down through the epiphysis
  • poor prognosis as the proliferative and reserve zones are interrupted
• type V
  • ruined or rammed
  • uncommon <1%
  • crushing type injury does not displace the growth plate but damages it by direct compression
  • worst prognosis
