The Evolution, Current State and Clinical Benefits of Far Cortical Fracture Fixation

Treatment of distal femur fractures have reported high fracture healing complications in several studies. The development of far cortical locking (FCL) technology results in improved fracture healing outcomes. There are biomechanical and animal studies demonstrating that the locked plating incorporating FCL screws provides a more flexible form of fixation compared to traditional locking plates (LP). Clinical studies have shown that the commercially available Zimmer Motionloc system with FCL screws provide good results in distal femur fractures and periporsthetic distal femur fractures. FCL constructs may help resolve fracture healing problems in the future. However, there is not enough available clinical evidence to conclusively indicate whether clinical healing rates are improved with FCL screw constructs compared to traditional LP's. Therefore, further prospective study designs are needed to compare FCL to LP constructs and to investigate the role of interfragmentary motion on callus formation. Level of Evidence: V.
