Reduction

The surgeon has to control three major deformities when performing open fixation of the distal femur with Condylar LCP:

  • Varus/valgus: The frontal plane alignment is determined by the fixation of the femoral articular block to the Condylar LCP with the distal locking screws. If the central 7.3 mm screw in the plate is parallel with the tibio-femoral joint surface, this ensures appropriate varus/valgus alignment.
  • Rotation: Careful monitoring of the rotation of the limb is observed throughout the operative procedure. The rotation becomes established once a distal screw and a proximal screw have been inserted.
  • Flexion/extension (sagittal plane alignment): The alignment of the Condylar LCP on the lateral aspect of the distal femur establishes the presence or absence of any extension, or flexion, deformity at the fracture site. After fixation of the plate to the distal femur, the flexion/extension relationship becomes established (“locked-in”) once a second screw is placed in the proximal main femoral fragment.
