Physeal fractures: Part 3. Classification.

Over the past 100 years, several attempts to classify physeal fractures have been made. Each new classification has made changes to the previously existing classifications. After review of these classifications and of data collected from a population-based study (see Physeal Fractures: Part 1. Epidemiology in Olmsted County, Minnesota, 1979-1988, pp. 423-30), a new classification was constructed. This classification includes two new fractures (see Physeal Fractures: Part 2. Two Previously Unclassified Types, pp. 431-38). This classification has sound anatomic, epidemiologic, and prognostic bases.
