Operative treatment of adolescent clavicle fractures with an intramedullary clavicle pin.

Background: Adolescent clavicle fractures have traditionally been treated nonoperatively; however, recent literature in adults has shown improved outcomes with operative treatment of displaced and shortened clavicle fractures. It has been suggested that these results may translate to adolescents. This study presents an initial look at outcomes for operative treatment of displaced midshaft clavicle fractures in adolescents using an intramedullary clavicle pin.
