The Synthes 4.5 mm LCP Proximal Tibia Plate is part of the LCP Periarticular Plating System, which merges locking screw technology with conventional plating techniques. The 4.5 mm LCP Proximal Tibia Plate has many similarities to traditional fixation methods, with a few important improvements. The technical innovation of locking screws provides the ability to create a fixed-angle construct while using familiar AO plating techniques. Locking capability is important for fixed-angle construct in osteopenic bone or mulitfragment fractures where screw purchase is compromised.
