Tiny Tips: SALTR for Pediatric Growth-plate Fractures

In Tiny Tips by Larissa HattinLeave a Comment

Up to one half of all children’s visits to the ED are orthopedic in nature [1]. Of these visits, approximately 35% are fractures that involve the growth plate, or physis, of a developing bone [2]. ED physicians must be familiar with the Salter-Harris classification system, which is the most commonly used system [3] for describing growth plate fractures.

An easy mnemonic to remember the fracture type and description is SALTR:

Type IStraight acrossFracture in directly through the physics, separating end from shaft
Type IIAboveFracture extends through metaphysis into physis. Most common fracture type, accounting for 75%of all growth plate fractures.
Type IIILowerExtends through physis into epiphysis, or lower aspect of the bone.
Type IIIIThroughExtends across metaphysis, physis, and epiphysis.
Type VRammedCrush injury to physis. Rarest type of growth plate fracture.

Reviewing with the Staff

Fractures involving the growth plates certainly are common injuries that we see in the ED. I am definitely a fan of mnemonics and SALTR is one of the ones that I use. When I’m teaching it, however, I always have to be careful to make sure “Above” and “Below\" aren’t seen as synonymous with “Proximal” and “Distal”, respectively. Salter Harris II of the distal radius will extend through the growth plate and then proximally into the physis, versus while Salter Harris II of the proximal phalanx will extend through the growth plate and then distally into the physis. When this is understood, this is a great mnemonic!
