【Abstract】 Objective To investigate the clinical therapeatic effectiveness of the femoral peritrochanteric fractures treated by the national-made improved proximal femoral nail (PFN), introduce the general components of the PFN and the operative procedures and discuss its biomechanical advantages and the difficulties in the operation.Methods Thirty-four cases of femoral peritrochanteric fractures were treated by the national-made improved proximal femoral nail (PFN) and their therapeatic effectiveness were followed up.Results All patients were followed up for an average duration of 6 months. The results showed that fracture of all cases healed up and the total excellent and good rate was 91%.Conclusion The PFN advances in solid internal fixation ,little invasive of operation, early exercises and fewer complications. It is one of the ideal choices to treat femoral peritrochanteric fractures and should be developed更多还原
