Intramedullary nailing of pediatric femoral shaft fracture.

Intramedullary nail fixation of pediatric long bone fracture, particularly femoral shaft fracture, has revolutionized the care and outcome of these complex injuries. Nailing is associated with a high rate of union and a low rate of complications. Improved understanding of proximal femoral vascularity has led to changes in nail insertion methodology. Multiple fixation devices are available; selection is based on fracture type, patient age, skeletal maturity, and body mass index. A thorough knowledge of anatomy and biomechanics is required to achieve optimal results without negatively affecting skeletal development.
