Femoral shaft fractures in children.

Femoral shaft fractures are the commonest diaphyseal fractures of childhood after those of the radial and ulnar shaft and the tibial shaft. Common mechanisms include falls, particularly from playground equipment, motor vehicle accidents and sporting injuries. Unlike in adults, femoral shaft fractures are commonly isolated injuries in children. In infants, they may be due to non-accidental injury. Treatment of femoral shaft fractures varies with the age and size of children, associated injuries and local practice. Current modalities used for the treatment of femoral shaft fractures include various forms of traction, immediate and late spica casting, elastic nailing, external fixation, plate fixation, and conventional intramedullary nailing for older children and adolescents. All these forms of treatment have been reported as being successful in cohort studies. Very few comparative studies exist. The main current controversies are the age at which elastic nailing becomes appropriate instead of conservative management, and secondly, the treatment of the older, heavier child for whom elastic nails may not be appropriate. Familiarity with several methods of femoral shaft stabilisation is appropriate. The major determinant in the choice of treatment is cultural.
