Abstract

A femur sliding screw plate is improved by adding flanges or wings on either side of a central portion, the flanges extending at least partially around the femur shaft. Preferrably, the flanges are provided integral to a centrally raised part which fits over a portion of the leg of a basic screw plate. Screw holes in the sliding screw plate align with screw holes in the basic screw plate and the sliding screw plate is attached to the basic screw plate and each screw plate is attached to the femur by common screws. The flanges each have screw holes, offset from the screw holes in the centralloy raised portion, screws being used to secure the flanges to outlying portions of the femur shaft in order to more fully consolidate fragments of the fractured femur. Alternatively a screw plate is provided with integral flanges extending from the leg of the screw plate.
