Objective To conclude the treatment of femoral shaft fractures with ipsilateral femoral neck or intertrochanteric fractures by dynamic condlar screw(DCS) and proximal femoral nail(PFN).Methods From January 1998 to June 2005,35 patients of femoral shaft fractures were studied.10 patients were associated with ipsilateral femoral neck fractures,25 patients with ipsilateral intertrochanteric fractures.9 cases were treated with DCS.26 cases were treated with PFN.Results The follow-up ranged from 6 to 30 months with an average of 18 months.All the fractures healed up well except that 2 cases happened with ischemic femoral necrosis.The rate fractures healing was 94%.Conclusion DCS is an ideal method to treat stable fractures.PFN is excellent in less invasion and shorten operation time.DCS and PFN have obvious advantages of reliable fixation short,clinical healing time and post-operative restored function.
