ABSTRACT

Locked compression plates or LCP, and the design of the combined holes in them, came to revolutionize the treatment of fractures; moreover, they are the gold standard in osteoporotic bone fractures; from the biomechanical point of view, they prevent movement in the fracture focus under the principle of absolute stability, producing a primary consolidation, or by reducing the movement at that level, which will result in a high secondary consolidation. The application of these plates is possible with minimally invasive techniques that provide an extra benefit of less disruption of periosteal vascularity because acting as external fixator and not having direct contact with the bone surface, bone physiology is affected to a lesser grade and increases the chances of cure. They exert three different biomechanical principles: compression, bridge plate and compression and bridge. They also have the possibility of anchoring with unicortical and bicortical screws, although it is not yet clear the indication of each possibility. They can be applied to complex fractures where other treatment options can hardly provide enough stability in osteoporotic or periprosthetic fractures. They are thus a resource that enables us to give patients another option for proper fracture stabilization, making for a recovery with minimal pain in a shorter period.
