The invention relates to medicine, namely to traumatology and orthopedics, and can be used for the treatment of diaphyseal fractures and metaepiphyseal distal femur.Based on the analysis of the prior art and identified drawbacks of known devices for osteosynthesis, the distal portion of the tibia, has been tasked to provide stable fixation of bone fragments at fractures, with a constant dynamic compression fractures of bone fragments in the area of the distal femur.This object is solved as follows. Retainer for osteosynthesis of fractures of the distal femur is formed as a plate containing diaphyseal part with holes, and metaepiphyseal portion having a bend, corresponding to the curvature of the distal portion of the femur and along the perimeter shaped pad with holes. Metaepiphyseal part retainer on opposite lateral sides has two parallel directed peripheral openings for administration monokortikalnyh derotation of screws and in its central part provided with openings for introducing bikortikalnyh converging screws, with the holes located on the perimeter of the curved areas have converging inner surfaces for introducing Kirschner wires.
