Salter-Harris fractures are fractures that affect the growth plate in skeletally-immature patients.
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.
|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.|
