Nail locking
We routinely lock all nails statically, due to the high rate of reported complications with unlocked or acutely dynamized nails (Whittle et aI., 1995). The number of screws used is determined by the fracture position, configuration, and comminution:
In simple, mid-diaphyseal fractures, one proximal and one distal static locking screw usually provides sufficient stability.
For a comminuted fracture, using two locking screws on each end is recommended.
For nonisthmic fractures, two or more screws are needed in the metaphysis closer to the fracture to better stabilize the nail in its relatively wide medullary space-the "mop-in-the-bucket" phenomenon-and avoid displacement .
Unless "back-slapping" is to be used (see Pearls), proximal locking is usually done first. The insertion jig´s cannulas usually offer multiple options from
