Tapping

Measure the drill depth and tap the malleolar fragment only with the 4.0 mm cancellous bone tap, using the protection sleeve. The length of the screw chosen is based on the principle that all thread must lie proximal to the fracture plane. Be careful not to choose a screw that is too long, as its thread will come to lie in the fattier cancellous bone of the metaphysis, rather than in the denser bone of the former epiphysis.
