Definitive articular surface fixation
Screws may be placed along the periphery of the articular surface of the
lateral femoral condyle going from lateral to medial to compress the
These screws may be fully threaded 3.5 mm lag screws (shown with gliding
hole), 6.5mm partially threaded lag screws, or 4.0/4.5 mm cannulated, partially
threaded lag screws.
Insertion of screws in this manner leaves a „free zone“ of bone into which a
laterally based plate system can be inserted (dotted circle).
