Objective     To discuss the therapeutic effect of clinical treatment of femoral intertrochanteric fractures with proximal femoral nail

especially the newly developed proximal femoral nail-A (PFN-A).      Methods     By AO classification

62 cases of femoral intertrochanteric fractures from 2002 to 2006 were divided into three groups (8 cases in group 31-A1

33 cases in group 31-A2

21 cases in group 31-A3) and were treated with multifunctional femur nail (MFN)

proximal femoral nail (PFN) and PFN-A instrumentation by means of closed reduction and fixation. The blood loss

operation time

fracture healing and functional recovery of the hip joint were observed.      Results     The mean blood loss was 90 ml

and the mean operation time was 60 min. Follow-up from 4 to 24 months after operation showed union of fracture in all cases

a disengaging hip screw in one case

and fat liquefaction of operation incisions in 2 cases

with the function recovery rate of 95.2% and no report of ischemia and necrosis of femoral head

and no malformation of hip varus.      Conclusion     The clinical treatment of femoral intertrochanteric fractures with PFN

especially PFN-A

is convenient

stable

miniinvasive and almost free from complications

which is applicable to patients of osteoporosis.
