A bone plate system is provided herein. The system may include a first and a second bone plate, which plates may be affixed to one or more bone portions and each other, so as to align and stabilize the bone and correct a bone fracture. A first bone plate is provided which includes both a bone contacting and a top surface, one of which corresponds to a primary plane. The first bone plate may be configured to engage a bone portion and a secondary plate. A secondary bone plate is provided, which plate is configured to engage the first plate. The secondary plate includes a bone contacting surface, which corresponds to one or more planes or an arc that are provided at an angle or substantially perpendicular to the primary plane. Methods of using such bone plating systems for the reduction, restoration and treatment of bone fractures are provided.
