TypeFrequencyDescriptionMnemonic
I6%–8%Slip along the axis of the growth plateSlip
II75%Fracture line extends proximally into the metaphysis from the physisAbove growth plate
III6%–8%Fracture line extends distally into the epiphysis from the physis (involves articular surface)Lower than growth plate
IV10%–12%Fracture line extends from the metaphysis, across the physis and epiphysisThrough growth plate
V1%Crush injuryRammed

Note: Types I and II usually heal without limitation of function; Types III and IV involve the articular surface and so may cause a
joint deformity; Type V injuries are likely to affect function of the joint adversely
