Reduction Techniques for Diaphyseal Femur Fractures.

Achieving and maintaining reduction in patients with a diaphyseal femur fracture may be difficult; therefore, thorough preoperative planning is required. To fully prepare for successful surgical management of diaphyseal femur fractures, surgeons must consider appropriate patient positioning and necessary tools, including surgical tables, traction devices, and instruments. Principles of acceptable reduction rely on the restoration of length, alignment, and rotation. Reduction of diaphyseal femur fractures should be attained in the least invasive manner, via percutaneous reduction techniques, if possible, to preserve fracture biology and promote successful fracture healing. Intraoperative assessment of reduction often requires imaging studies of the contralateral extremity as a reference. Intraoperative assessment for associated femoral neck fractures and postoperative clinical examination of the hip and knee are imperative to the successful management of diaphyseal femur fractures. Other reference modalities and clinical examinations are required in patients with bilateral diaphyseal femur fractures.
