Compression hip screw nail-plate system for intertrochanteric fractures

Background. The worldwide increased incidence in fractures of the proximal end of the femur is increasing with the parallel increase in the average age of the population. The advanced age and poor physical condition of these patients render surgery necessary. Methods. In 1999, at the Orthopaedic Clinic of the University of Siena, 56 patients were treated with the compression hip nail-plate system, a new synthesis device for the treatment of peritrochanteric fractures. The system consists of a new dynamic cephalic screw that could be combined with a plate or a femoral nail. The dynamic cephalic screw of the BCM system has a limited sliding method, impeding excursions greater than 10 mm and preventing excessive collapse of the fracture fragments that can evolve into a shortening of the limb. The canulated nail has a diameter of only 9 mm, which permits insertion into the shaft canal without reaming. Results. Four patients with a follow-up of less than 3 months, 2 patients lost to control, and 1 patient who died were excluded from the study. All 49 remaining patients healed clinically and radiographically within 3 months. Conclusions. The possibility of the double combination of the screw with a plate or with an intramedullary nail permits the surgeon to have a double solution with a single instrument at hand, and offers the opportunity of changing the choice of synthesis method to implant even during surgery.
