Limb Rotation in Lower Extremity Fractures.

Fractures of the tibia and femur are common. Rotation of the limb can affect the outcome of the injury, both in the immediate term and the long term. Because plain radiographs are two dimensional, rotation is hard to assess radiographically. As a result, rotational malalignment is common. It is important to provide technical tips on the assessment of rotation preoperatively, intraoperatively, and postoperatively. The goal is to better assess rotation so that deformity can be minimized. This applies to fractures of the tibia and femur. Even after careful treatment, rotational deformities can occur. When they are symptomatic, correction should be considered. Techniques for correction of malrotation of both tibial and femoral fractures are presented.
