System and method for fixing a distal femur having a Hoffa fracture. The system may comprise a main plate, an outrigger plate, and a coupling member that mounts the outrigger plate to the main plate. In an exemplary method, an elongated body portion of the main plate may be secured to a shaft region of the distal femur, and a wider head portion of the main plate may be secured to an end region of the distal femur. The outrigger plate may be mounted on the head portion of the main plate, and an arm of the outrigger plate may be fastened to a condylar fragment of the femur with one or more fasteners, such that the outrigger plate spans and stabilizes the Hoffa fracture. 1. A method of fixing a distal femur having a Hoffa fracture creating a condylar fragment , the method comprising , in any order:securing a main plate having an elongated body portion and a head portion to the distal femur, wherein the elongated body portion is secured to a shaft region of the distal femur, and wherein the head portion is wider than the body portion and is secured to an end region of the distal femur;selecting an orientation for an outrigger plate from two or more orientations permitted by an interface between the main plate and the outrigger plate;mounting the outrigger plate firmly on the head portion of the main plate at the selected orientation with a coupling member; andfastening an arm of the outrigger plate to the condylar fragment with one or more fasteners such that the outrigger plate spans and stabilizes the Hoffa fracture.2. The method of claim 1 , wherein the outrigger plate is substantially shorter claim 1 , narrower claim 1 , and thinner than the main plate.3. The method of claim 1 , wherein the step of selecting an orientation for an outrigger plate includes a step of selecting an orientation from a finite series of discrete orientations permitted by the interface between the main plate and the outrigger plate.4. The method of claim 3 , wherein the step of mounting an ...
