Risk of impaired growth increases as fractures progress from type I through type V In English, a useful mnemonic for the types is SALTR: Salter I: S = S traight (the fracture line goes straight across the growth plate) Salter II: A = A bove (the fracture line extends above or away from the growth plate) Salter III: L = L ower (the fracture line extends below the growth plate) Salter IV: T = T hrough (the fracture line extends through the metaphysis, growth plate, and epiphysis) Salter V: R = R ammed (the growth plate has been crushed) Children with injuries that involve the epiphysis as well as the growth plate (Salter types III and IV) or that compress the growth plate (Salter type V) tend to have a worse prognosis.
