ABSTRACT
Objective To evaluate the effect of proximal femoral nail antirotation (PFNA) with autogenous bone grafting for salvage of failed internal fixation of intertrochanteric hip fracture.Methods Between January 2007 and June 2012,21 cases of intertrochanteric fractures who had failed internal fixation initially were treated with revision open reduction and PFNA internal fixation and autogenous bone grafting.There were 9 men and 12 women with the mean age of 54 years (range,27-76 years).In the initially failed internal fixation,dynamic hip screw (DHS) was used in 7 cases,locking proximal femoral plate (LPFP) in 8 cases,Gamma nail in 2 cases,proximal femoral nail (PFN) in 2 cases and home-made reconstruction nail in 2 cases.Results Mean operation time was 150 minutes (range,100-240 minutes) and mean blood loss was 800 ml (range,400-2,000 ml).There were no serious complications during operation.Mean follow-up was 26 months (range,6-66 months).Bone healing was achieved at mean 4 months (range,3-8 months) in all cases.Harris hip score was (42.1 ±3.2) points (range,36-48 points) before operation and (87.2 ± 3.8) points (range,62-94 points) at the final follow-up,with significant improvement in hip function (P < 0.05).At the final follow-up,no avascular necrosis of the femoral head or hip degeneration occurred and mean neck-shaft angle was 130° (range,110°-142°).Conclusions Once the fracture patients with strong ability of action,massive proximal femoral residuals,and non-serious hip injury,revision PFNA internal fixation with autogenous bone grafting is effective.Complete preoperative evaluation and attention to specific technical details may improve success rate and reduce complications.
