Importance of a moderate plate-to-bone distance for the functioning of the far cortical locking system

The main objective of any bone fixation device is to achieve fracture union. Conventional methods that use dynamic compression plates rely on a very rigid construct to allow direct bone healing. In recent decades, the internal fixation of long bone fractures has developed, and now involves biological, rather than mechanical methods; thus, more flexible constructs are favored to induce secondary bone healing by callus formation [1 –3]. With the introduction of locking compression plates as a fixed-angle screw locked mechanism, this technique avoids the need for precise reduction and plate compression against the underlying bone while preserving periosteal blood supply [1].
