ABSTRACT
Objective To investigate the treatment of proximal femoral nail antirotation (PFNA) in pertrochanteric hip fractures with unstable lateral-wall.Methods Thirty-two cases were included from the April 2009 to May 2011.Recorded operation period,blood loss volume,and complications and evaluated the effect of the methods.Arrange referral at 6 weeks,3 months,6 months,12 months respectively after operation,to check limb function and conventional camera hips,lateral X-ray film.Postoperative functional evaluation using the Harris hip score.Measure the last follow-up neck shaft angle and compare with postoperative's.Results The average operation period was (60-190) min,average was (80 ± 5) min ; blood loss volume was (90-250)ml,average was (120 ± 9) ml ; Average hospital periods was (15 ± 7) days; weight loading time was (6.3 ± 1.2)weeks after surgery and average time of union of fracture was 3.6 months.All patients obtained union of fracture without complications such as varus,internal fixation cutting out.Conclusion PFNA was proved to be an effective way for treating unstable lateral-wall of pertrochanteric hip fractures due to its advantages of stable fixation,minor trauma,less complications.
