An X-ray of the left ankle showing a Salter–Harris type III fracture of medial malleolus. Black arrow demonstrates fracture line while the white arrow marks the growth plate.

- Type I – transverse fracture through the growth plate (also referred to as the "physis"): 6% incidence
- Type II – A fracture through the growth plate and the metaphysis, sparing the epiphysis: 75% incidence, takes approximately 2–3 weeks to heal.
- Type III – A fracture through growth plate and epiphysis, sparing the metaphysis: 8% incidence
- Type IV – A fracture through all three elements of the bone, the growth plate, metaphysis, and epiphysis: 10% incidence
- Type V – A compression fracture of the growth plate (resulting in a decrease in the perceived space between the epiphysis and diaphysis on x-ray): 1% incidence
- Type VI – Injury to the peripheral portion of the physis and a resultant bony bridge formation which may produce an angular deformity (added in 1969 by Mercer Rang)
- Type VII – Isolated injury of the epiphyseal plate (VII–IX added in 1982 by JA Ogden)
- Type VIII – Isolated injury of the metaphysis with possible impairment of endochondral ossification
- Type IX – Injury of the periosteum which may impair intramembranous ossification
SALTER mnemonic for classification
- I – S = Slip (separated or straight across). Fracture of the cartilage of the physis (growth plate)
- II – A = Above. The fracture lies above the physis, or Away from the joint.
- III – L = Lower. The fracture is below the physis in the epiphysis.
- IV – TE = Through Everything. The fracture is through the metaphysis, physis, and epiphysis.
- V – R = Rammed (crushed). The physis has been crushed.
(alternatively SALTER can be used for the first 6 types - as above but adding Type V: 'E' for Everything or Epiphysis and Type VI:'R' for Ring)
