Entry point - lateral view

With a power drill or hand chuck, insert the 2.5 mm guide wire through the metaphysis and into the medullary canal. Direct the wire so it is parallel to the anterior cortex and closely approximates the 9° angulation of the proximal nail. To ensure correct wire placement, hold a sterile nail anterior to the tibia and use it as an angle guide. Confirm wire placement with the image intensifier.

Place the 11 mm Cannulated Drill Bit into a cannulated drill and place the protection sleeve over the guide wire. Place the drill bit over the 2.5 mm guide wire and through the protection sleeve. Drill an opening into the medullary canal to a depth of approxi- mately 100 mm. Remove the drill, guide wire and drill sleeve.
