摘要：An improved method and apparatus for reducing a hip fracture utilizing a
minimally invasive procedure which does not require incision of the quadriceps. A femoralimplant in accordance with the present invention achieves intramedullary fixation as wellas fixation into the femoral head to allow for the compression needed for a femoralfracture to heal. To position the femoral implant of the present invention, an incision ismade along the greater trochanter. Because the greater trochanter is notcircumferentially covered with muscles, the incision can be made and the wound
developed through the skin and fascia to expose the greater trochanter, without incisingmuscle, including, e.g., the quadriceps. After exposing the greater trochanter, novelinstruments 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 fromthe greater trochanter into the intramedullary canal of the femur. After preparation ofthe femoral cavity, a femoral implant in accordance with the present invention is insertedinto the aforementioned cavity in the femur. The femoral implant is thereafter secured inthe femur, with portions of the implant extending into and being secured within thefemoral head and portions of the implant extending into and being secured within thefemoral shaft.
