Salter-Harris Classification
Pronunciation: SAWL-ter HAIR-is
A system for classifying pediatric growth plate fractures into five types based on fracture pattern.
Full Definition
The Salter-Harris classification is a widely used system for categorizing physeal (growth plate) fractures in children, developed by Robert Salter and W. Robert Harris. The system divides fractures into five types: Type I (straight across the physis), Type II (through physis and metaphysis), Type III (through physis and epiphysis), Type IV (through all structures), and Type V (compression injury to physis). Each type has different implications for treatment and prognosis, with higher numbers generally indicating worse outcomes and greater risk of growth disturbance. The mnemonic "SALTR" (Straight, Above, Lower, Through, Ram) is commonly used to remember the classification.
Usage
Usage note: Named after Salter and Harris; capitalize as eponym. Roman numerals typically used for types (I-V).
