Illustration of the Salter-Harris classification of physeal fractures.
Case Discussion
Salter-Harris classification is used to describe physeal fractures. The classification can be remembered using the SALTR mnemonic:
- S: slipped (type I)
- A: above or away from joint (type II)
- L: lower (type III)
- T: through or transverse or together (type IV)
- R: rammed or ruined (type V)
Type V fractures are oftentimes occult on initial radiographs. They are usually diagnosed late during follow-up when there is a bone deformity or growth arrest.
In the illustration, the metaphysis is drawn above the epiphysis so the SALTR mnemonic can be properly used.
