  • Publication number: 20070225721
    Abstract: An improved method and apparatus for reducing a hip fracture utilizing a minimally invasive procedure which does not require incision of the quadriceps. A femoral implant in accordance with the present invention achieves intramedullary fixation as well as fixation into the femoral head to allow for the compression needed for a femoral fracture to heal. To position the femoral implant of the present invention, an incision is made along the greater trochanter. Because the greater trochanter is not circumferentially covered with muscles, the incision can be made and the wound developed through the skin and fascia to expose the greater trochanter, without incising muscle, including, e.g., the quadriceps. After exposing the greater trochanter, novel instruments of the present invention are utilized to prepare a cavity in the femur extending from the greater trochanter into the femoral head and further extending from the greater trochanter into the intramedullary canal of the femur.

  • Publication number: 20070093840
    Abstract: A flexible shaft. In exemplary embodiments, the flexible shaft can be used for the transmission of rotary motion and/or curvilinear guidance. In one embodiment, the flexible shaft includes a plurality of shaft segments linked together via at least one flexible elongate member. The shaft segments are spaced along the at least one flexible elongate member. Some of the shaft segments are displaceable relative to the at least one flexible elongate member. Orbiting of the at least one elongate member about a central axis of the shaft induces rotation of the shaft segments about the central axis, thereby effecting rotation of the flexible shaft.
