Predrilling

Unless self-drilling pins are to be used it is essential to predrill both cortices prior to the insertion of threaded pins.

Place a drill sleeve with trocar through the prepared soft-tissue channel to prevent damage to soft tissues, and confirm correct positioning. The use of an image intensifier may be beneficial to determine correct pin trajectories.

Drilling through cortical bone should be performed under cooling to prevent heat formation followed by bone necrosis.
