摘要：
A hip screw assembly for fixation of a fractured femur includes a screw and a plate for engaging the femur. It includes a barrel having a cavity therein which is secured to the plate. The screw includes a portion which is fitted in the cavity of the barrel. A stop is positioned in the barrel, to provide a limit on the movement of the screw in the barrel. The screw and the barrel define a first arrangement there between in which the screw is slidably moveable in the cavity of the barrel a first selectable predetermined distance and a second arrangement there between in which the screw is slidably moveable in the cavity of the barrel a second selectable predetermined distance. The second distance is greater than the first distance.
