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
- 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.
