Objective:To explore the related complications and management in the treatment of intertrochanteric fractures of femur with proximal femoral nail(PFN).Methods:42 cases of intertrochanteric fractures of femur treated with PFN that could be followed up during September 2005 to May 2010 in my hospital were retrospectively analyzed.There were 18 males and 24 females with an average age of 78 years(ranging from 51 to 90 years).According to Tronzo-Evans classification

there were 3 cases for typeⅠ

15 cases for typeⅡ

10 cases for typeⅢ

9 cases for typeⅣ

and 5 cases for typeⅤ.Results:All the patients were followed up for a mean time of 30 months(ranging from 5 to 60 months).No wound infection

DVT

coxa vara or ANFH occurred in these cases.One patient presented with proximal femoral fracture in the operation.Two patients suffered cutting out and screw breakage.One patient complained of pain in the injured buttock and great trochanter.Conclusion:Exact reduction

strict aseptic operation

reasonable application of antibiotics

ideal insertion of internal fixators

active treatments for osteoporosis

individual healing exercise and comprehensive prevention of DVT are the keys to avoiding the complications.
