Fractures of the Physis POSNA Study Guide

Description: Objectives
1. Describe the layers of the growth plate, and describe the mechanical strength of each layer.
2. Describe the periphery of the physis, and the role these structures play in mechanical stability of the physis
3. Describe the Salter-Harris classification of growth plate injury
4. Discuss the variations noted in actual fracture patterns from the idealized classification and the reasons underlying such variation
5. Describe factors which may contribute to premature physeal arrest
6. Discuss strategies which can minimize the incidence of subsequent physeal arrest following physeal fracture
