Review: systemic effects of femoral nailing: from Küntscher to the immune reactivity era.

Abstract

Intramedullary nailing is the preferred treatment for stabilizing femoral diaphyseal fractures. Despite the superior biomechanical advantages over other implants, its use especially in some selected groups of patients, has been questioned because of possible harmful systemic effects of intramedullary reaming. The lung seems to be the primary target for fat embolization and for mediated effects by inflammatory reactions. The latter are initiated in the immediate aftermath after injury, and femoral nailing can amplify these responses. The role of reaming in the context of early femoral fracture fixation in the patient experiencing trauma is debatable. This review article focuses on the evidence that has emerged during the past century regarding the systemic effects of femoral nailing.
