Determine the length of the screw with the appropriate depth measuring device.
The chosen 3.5 mm partially threaded cannulated screw must lie with its threads completely beyond the fracture line and totally within the Volkmann's fragment to achieve interfragmentary compression. If possible, engage the far cortex. Use a washer.
If the thread of the 3.5 mm partially threaded screw would still come to lie on both sides of the fracture, to avoid significant protrusion with a longer screw, a fully threaded screw may be used, overdrilling the anterior tibia to form a 3.5 mm gliding hole.
