The present invention relates to a medial buttress construct and a fracture fixation device for femoral neck, and the medial buttress construct for femoral neck comprises a support part and an attachment fixing part； the support part and the attachment fixing part are fixedly connected to each other. The support part is provided with a structure matching inferior surface of proximal end of the femoral neck, the attachment fixing part is provided with structures simultaneously matching front side surface of distal end of the femoral neck and front side surface of upper end of femoral shaft, and the attachment fixing part is provided with at least one opening for allowing a screw to pass through on the structure matching the front side surface of the distal end of the femoral neck, and at least one opening for allowing a screw to pass through on the structure matching the front side surface of the upper end of the femoral shaft. The medial buttress construct for femoral neck can well supports the femoral neck fracture part, so that the great torsion force and shear force borne by the femoral neck fracture part are greatly reduced, assisting the fracture part with the accurate positioning, and the stability and heal effect after reduction of the femoral neck fracture are effectively ensured.
