Drill for second screw
Towards the proximal apex of the fracture line, drill a gliding hole for a
diaphyseal lag screw. This screw, too, should be placed as perpendicularly to
the diaphyseal fracture plane as possible, using a 1.3 (or 1.0) mm drill bit
for a 1.3 (or 1.0) mm screw. Insert a 1.3 (or 1.0) mm drill sleeve into the
Use a 1.0 (or 0.8) mm drill bit to drill a thread hole in the opposite
fragment, just through the far (trans) cortex.
