a: Illustration depicting the far cortical locking screw for unicortical fixation in the far cortex, enabling elastic flexion of the screw shaft within the motion envelope (Δd) in the near cortex. b: Mechanically, the far cortical locking (FCL) construct functions as an internal fixator that derives axial flexibility by cantilever bending of the far cortical locking screw shafts similar to an external fixator that derives elasticity from fixation pin flexion. c: A staggered and converging far cortical locking screw arrangement was implemented to improve construct strength in torsion.
