摘要：
An instrument for locating an axis of a blocking screw is disclosed. The instrument is applicable for a retrograde installation of a femoral intramedullary device or an antegrade installation of a tibial intramedullary device. The instrument includes a drill jig with a radiolucent frame portion and a mounting portion. The mounting portion is adapted to connect to an intramedullary device, and the frame portion has at least one aperture for locating the axis of the blocking screw. The drill jig is adjustable to locate the aperture in a longitudinal or rotational direction relative to the intramedullary device.
