- Locking Plates: LCP Locking Compression Plate.
- locking screws makes plate fixation more resistant to failure from screw loosening and pullout;
- for failure to occur, a locking screw construct will fail as a unit as opposed to sequential screw failure with non locking plates;
- far cortical locking:
- over drilling the near cortex;
- goal is to promote callus on the near cortex;

- Effects of Hybrid Plating With Locked and Nonlocked Screws on the Strength of Locked Plating Constructs in the Osteoporotic Diaphysis
- pitfalls
- hardware failure:
- repeated stresses concentrated over the fracture site can exceeded the mechanical stiffness of the locked plate, leading to plate bending or plate fracture;
- use of a longer plate can better distributed the stresses associated with weightbearing at the fracture site;
