Prepare insertion of a lag screw
Drill a gliding hole in the near cortex, through the plate hole closest and just distal to the fracture, using a 3.5 mm drill bit. The hole should be drilled as perpendicularly to the fracture line as possible.
Insert a 2.5 mm drill sleeve inside the gliding hole and drill the threaded hole in the far cortex with a 2.5 mm drill bit.
Measure the depth of the hole with the hook of the depth gauge pointing proximally.
Tap the far cortex with the 3.5 mm cortical tap.
