This chapter presents common and unusual pediatric fracture patterns and mechanisms of injury. A detailed discussion of growth cartilage injury follows a brief presentation on cartilage development, reviewing the Salter-Harris classifi cation and the Ogden extended classification. Other unique pediatric injuries including apophyseal avulsion fractures and pediatric stress fractures are also discussed. Pediatric fracture healing and remodeling and potential complications are presented. Finally, there is a brief discussion of pediatric articular trauma.The dynamic state of the developing skeleton makes children susceptible to unique mechanisms of injury, resulting in specifi c fracture patterns. Pediatric fractures may result from acute or chronic/repetitive trauma; typical mechanisms of injury include a fall, motor vehicle collision, or sporting injury. The type of fracture that occurs depends on the child's age. Fractures in infants are often diaphyseal, whereas older children commonly sustain fractures involving the metaphysis or metadiaphysis (Fig. 17.1 ) [ 1 ]. Since pediatric bone is relatively elastic, several fractures-such as greenstick, buckle, and bowing injuries-are essentially limited to children. Growth plate fractures represent up to 25 % of all pediatric fractures, and additional growth cartilage injuries include osteochondral and apophyseal fractures [ 2 , 3 ].
