1. Apparatus for treating fractures of the femur comprising:

  • an intramedullary rod having a longitudinal axis and defining a coaxial bore therethrough, said rod having a proximal head and a stem distal thereto, and being adapted in use for insertion into the marrow canal of a femur;

    said stem having at least one pair of stem holes, both holes of said at least one pair of stem holes being coaxially arranged on a common axis extending through said bore in a transverse direction relative to the longitudinal axis of said rod;

    said head having at least a distal pair of head holes and a proximal pair of head holes, both holes of each said distal and proximal pairs of head holes being coaxially arranged on a common axis extending through said bore in an angled direction relative to the longitudinal axis of said rod such that when said rod is in position within the marrow canal of the femur said axes of said distal and proximal head holes are directed toward the head of the femur, said common axes of said distal and proximal pairs of head holes being generally parallel to each other; and

    a screw for insertion through said distal pair of head holes, said screw having a threaded surface formed at the end adapted in use to engage the head of the femur and a smooth surface formed on the remaining major portion of its length, said smooth surface being adapted in use for continuous sliding contact with said head of said rod through said distal pair of head holes to permit sliding compression of selected fractures.
