In principle uses 3 point fixation.

Pre bend 3* diameter of isthmus (where using two nails). Debatable some surgeons dont pre bend allow nails to follow contour of bone.

Ensure the apex of the bend is at the level of fracture site.

Balance is important, use entry points at same level, use nails of similar diameter and bend. (Unless really advanced TENS nailing and using smaller nail to balance forces of muscle pull).

Use nail 40% of diameter if using 2 nails eg. Femur or Tibia;  60% if only using one nail eg. Radius and Ulna.

Retrograde nailing of radius and ante or retrograde nailing of ulna

Single nail hence 60% diameter canal.

Pre bending not normally necessary, ulna is straight, if bending radius consider bow of radius.
