Integration of the bone tissue through the screw threads could be introduced as the main reason of complications in treatment of bone fractures using trauma plating systems. Today, specific trauma plates are developed to be placed in wider aspects of the bones for effective buttressing and capturing of the bone fragments. In view of operation methods, minimal invasive and open invasive operation methods are nowadays extensively used in fixation of bone fractures and would allow accessibility of the surgeon through the fracture site. Surgical tools and instruments would also provide temporary reduction of the bone fragments in anatomical position and insertion of various types of screws through the bone. Utilization of image processing pre, intra, and post-operatively have enhanced management of fracture fixation in rigorous controlled plan. Incorporation of allograft or autografts has facilitated healing of the bone in cases with bone loss after trauma injury.

With consideration of all mentioned accomplishments, fixation of bone fracture with multiple fragments is still in challenge. In fact, if all above considerations related to the plate design, operation method, utilization of instruments, utilization of image processing facilities, etc. are managing perfectly, there would be still doubt on success of the plating fixation in treatment of multi-fragmentary fractures.
