ABSTRACT:
A prosthesis for the primary replacement of intertrochanteric fracture fragments to prevent the multitude of complications resulting from open reduction and nailing of intertrochanteric fractures. The prosthesis replaces the femoral head, neck and comminuted trochanteric portion including the lesser trochanter. The shaft of the femur is cut to form a square notch for prosthetic insertion and seating with the base of this notch approximately at the level of the inferior border of the lesser trochanter. When a proper fit has been accomplished the prosthesis is cemented into the femoral shaft and is then reduced into the acetabulum. When the greater trochanteric fragment is fractured transversely, it can be repositioned and held with wire secured through the holes in the prosthesis. The treatment is particularly useful with elderly patients since weight bearing can take place almost immediately followed by early ambulation.
