Salter-Harris Classification for Growth Plate Injuries


There is a simple mnemonic that is often used to help remember the different types of Salter-Harris Fractures, using the letters S-A-L-T-R.

 Letter Type Key Word  Description



 Straight Across The fracture traverses through the cartilage of the physis.
A II Above The fracture is located mostly above the physis. It starts in the metaphysis and exits back out through the physis, avoiding the epiphysis completely.
L III Lower The fracture is “lower” than the physis. It starts in the epiphysis and exits out the physis, avoiding the metaphysis.
T IV Through The fracture travels “through” the physis. It actually starts in the metaphysis and crosses all the way through the physis, exiting out of the epiphysis.
R V Rammed The injury to the physis is a crush type injury, resulting in significant damage.
