BONE FIXATION DEVICE

摘要

A bone fixation device for repairing a fracture of the proximal femur is disclosed. It includes a jack tube, a compression screw and a nail. The jack tube is an elongated tubular member having a base plate and a side wall defining central passageway. The base plate is arranged to be secured to the femur by screws. The side wall of jack tube includes plural longitudinally extending slots. The nail is a tubular member having plural linear blades located in respective slots in the jack tube and plural spikes extending out of the distal end of the nail. The compression screw is arranged to be disposed within the nail to form a slidable unit and has internal threads to engage threads in the jack tube so that rotation of the compression screw slides the nail down the jack tube, with the blades and spikes digging into the surrounding bone.
